Bozeman Defends Ph.D. Dissertation
Michael D. Bozeman Jr., a Georgia Tech Aerospace Systems Design Laboratory graduate student, working at NASA LaRC, defended his Ph.D. dissertation, “A Reduced-Order Modeling Methodology for the Multidisciplinary Design and Analysis of Boundary Layer Ingestion Configurations.” His committee included: from the Georgia Tech School of Aerospace Engineering Prof. Dimitri Mavris (advisor), Prof. Marilyn Smith, and Dr. Jimmy Tai; and from NASA Langley Dr. Melissa Carter and Dr. Irian Ordaz. The abstract of his thesis is below.
In response to the increasingly stringent requirements for subsonic transport aircraft, NASA has established aggressive goals for the noise, emissions, and fuel burn of the next generations of aircraft. This has led to the investigation of a variety of unconventional configurations and new technologies. Boundary Layer Ingestion (BLI) propulsion has been identified as a promising technology to reduce fuel burn. Preliminary studies show that BLI propulsion can offer a 3-12% reduction in fuel burn, depending on the configuration. Traditionally, the design and analysis of the airframe and propulsion system has been performed in a decoupled manner. For BLI configurations, the propulsion system is tightly integrated into the airframe resulting in strong interactions between the airframe aerodynamics and propulsion system performance. As a result, the design and analysis of BLI configurations require coupled multidisciplinary analysis (MDA) consisting of an aerodynamic analysis in an iterative loop with a propulsion system analysis. This is a very expensive analysis considering the requirement for high-fidelity models.
Additionally, the design of highly-coupled configurations cannot rely solely on intuition to make design decisions. Advanced methods including Multidisciplinary Analysis and Optimization (MDAO) and design space exploration are needed to allow for the design decisions to be made based directly on a system-level objective (e.g., fuel burn) and to allow for design studies to provide insight into the multidisciplinary trades associated with BLI configurations. However, MDAO and design space exploration using coupled, high-fidelity analysis models, are not practical. In this work, reduced-order modeling (ROM) is proposed as a potential solution to reduce the computational cost associated with the coupled MDA of BLI configurations and to enable these advanced design methods. An interpolation-based POD ROM is developed based on the CFD analysis to allow for predictions of the aerodynamics over a range of propulsor operating conditions for a simplified tail-cone thruster (TCT) configuration.
The resulting ROM is then coupled to a propulsion model to perform ROM-based, coupled MDA. Finally, the ROM-based coupled MDA approach is employed for coupled MDAO to assess the performance benefit offered relative to equivalent CFD- and adjoint-based approaches. The results show that the ROM-based coupled MDA approach offers an improvement in performance relative to the current state of the art. Relative to the equivalent CFD-based approach, the ROM-based, coupled MDA method demonstrated significant computational savings for even a single optimization. However, the ROM-based approach requires multiple optimizations to offer a computational benefit over the adjoint-based approach. This result highlights the benefit of the proposed approach for optimization studies and design space exploration.

Question and Answer Interface Session Conducted for 2020 RASC-AL Challenge
On Thursday, Oct. 31, 2019, NIA and NASA co-hosted a webinar-based Q&A Session for teams interested in participating in the 2020 RASC-AL Competition. Teams who submitted a Notice of Intent by the deadline of Oct. 4 were invited to participate in the Q&A and were encouraged to submit questions in advance. One hundred forty-three questions were pre-submitted and compiled into a visual chart deck for the webinar by the RASC-AL program team. During the Q&A session, RASC-AL sponsors, Patrick Troutman and Christopher Jones, provided verbal and written answers to the questions and were supported by NIA’s RASC-AL team: Shelley Spears, Stacy Dees and Genevieve Ebarle (RASC-AL Program Director, Manager and Coordinator, respectively).
This year’s RASC-AL competition asks undergraduate and graduate student teams to develop new concepts that leverage innovations to improve human ability to operate in space and on distant planetary bodies within five themes: South Pole Multi-Purpose Rover, International Space Station (ISS) as a Mars Mission Analog, Short Surface Stay Mars Mission, Commercial Cislunar Space Development, and Autonomous Utilization and Maintenance for Science Payloads on the Gateway and/or Mars-class Transportation.
A complete transcript and audio recording of the Q&A session will be posted on the RASC-AL website FAQs page, rascal.nianet.org/faqs, by Wednesday, Nov. 6.
NIA Associate Research Fellow Attends CMH017 Meeting
Dr. Ronald Krueger, Associate Fellow at the National Institute of Aerospace (NIA), traveled to Wichita, Kansas, to attend the CMH-17 (Composite Materials Handbook) meeting Oct. 21-24, 2019. The Composite Materials Handbook creates, publishes and maintains proven, reliable engineering information and standards, subjected to thorough technical review, to support the development and use of composite materials and structures. Therefore, experts from the field periodically meet regularly to discuss critical technical issues for composite structural applications. Stakeholders in this activity are the certification authorities (FAA, EASA), industry, academia and government research facilities. It is envisioned that in the future CMH-17 will be the authoritative, worldwide focal point for technical information on composite materials and structures.
It is planned that lessons learned during NASA’s Advanced Composites Program (ACP) will be published in revision H of CMH-17. Dr. Krueger participated in technical meetings of the Testing, and Sandwich Working Groups as well as the Damage Tolerance Task Group. He chaired a meeting of the Disbonding and Delamination Task Group (DDTG), which determines an overall strategy for the handbook to address disbonding and delamination of composites and examines methodologies needed to assure through-thickness integrity of bonds and laminations in polymer matrix composites. The meeting focused on new items, which are envisioned for inclusion in the upcoming revision H of the handbook.
Currently, it is expected that revision H will be published in the 2021-2022 timeframe. Existing items in Volume 1 need to be revised, including the chapters on fracture toughness testing under static and fatigue loading. New items include the addition of fracture toughness data to Volume 2, the addition of a chapter on cohesive zone modeling for disbonding/delamination analysis and a new chapter on disbonding/delamination arrest methods, such as stitching, Z-pinning and rivets.
Dr. Krueger also organized a four-hour focused working meeting of the Sandwich Disbond Growth Teamafter the CMH-17 main meetings. The Sandwich Disbond Growth Teamwas established as a group of experts within the CMH-17 Disbond and Delamination Task Groupin 2011 to identify, describe and address the phenomenon of sandwich face sheet/core disbonding. This failure mode is of particular interest to the FAA from their perspective of Continued Operational Safety (COS) since several in-service occurrences have been observed which can pose a threat to the structural integrity of an aircraft or spacecraft component.
Leif Carlsson (Florida Atlantic University) and George Kardomateas (Georgia Tech) presented their work which had been performed under a cooperative agreement between the NIA and the FAA. The remainder of the meeting focused on the predominantly mode I Single Cantilever Beam (SCB) test and efforts toward ASTM standardization. Next steps toward an additional SCB-based test procedure for fatigue testing were discussed. The development of new test methods for mixed-mode I/II and predominantly mode II was also discussed.
NIA Research Engineer Presents at NASA Langley CFD Working Group Meeting

NIA Research Scientist Presents at World Congress on Formal Methods
Dr. Mariano Moscato, Research Scientist at the National Institute of Aerospace (NIA), presented “Provably Correct Floating-Point Implementation of a Point-in-Polygon Algorithm,” co-authored by Laura Titolo (NIA), Marco Feliu (NIA), and Cesar Munoz (NASA Langley) at the 23rdWorld Congress on Formal Methods (FM 2019). FM 2019 was held in Porto, Portugal Oct. 7-11, 2019.
“The problem of determining whether or not a point lies inside a given polygon occurs in many applications. In air traffic management concepts, a correct solution to the point-in-polygon problem is critical to geofencing systems for Unmanned Aerial Vehicles and in weather avoidance applications. Many mathematical methods can be used to solve the point-in-polygon problem. Unfortunately, a straightforward floating-point implementation of these methods can lead to incorrect results due to round-off errors. In particular, these errors may cause the control flow of the program to diverge with respect to the ideal real-number algorithm. This divergence potentially results in an incorrect point-in-polygon determination even when the point is far from the edges of the polygon.
This paper presents a provably correct implementation of a point-in-polygon method that is based on the computation of the winding number. This implementation is mechanically generated from a source-to-source transformation of the ideal real-number specification of the algorithm. The correctness of this implementation is formally verified within the Frama-C analyzer, where the proof obligations are discharged using the Prototype Verification System (PVS).”

NIA Associate Principal Engineer Presents at 70thIAC
Menachem Rafaelof, Associate Principal Engineer at the National Institute of Aerospace (NIA), presented “Implementation of Machine Learning to Gauge Human Response to Noise to Eliminate its Adverse Effects Onboard Spacecraft,” co-authored by Andrew Schroder (NASA Langley) at the70th International Astronautical Congress (IAC). This paper was selected for presentation within the Space Life Science Symposium under the “Human Physiology in Space” technical session. About 75 researchers from around the world attended this presentation. The 70thIAC took place in Washington, D.C., on Oct. 22-25, 2019.
Crew compartments onboard spacecraft are very confined spaces designed to support the presence and functions of its inhabitants around-the-clock. As such, these compartments include extensive machinery for life support, climate control, and vehicle operations. This makes crew compartments very noisy spaces posing adverse physiological and psychological effects to its inhabitants. The relationship between noise and human response to it is extremely complex, as noise may include numerous features, each evoking a different degree or type of response from different observers. Still, precisely relating human response to noise and its causes is extremely valuable for the design of systems that limit the adverse effects of noise.
Recent research by the authors has demonstrated the feasibility of using machine learning algorithms to predict human response to complex sound originated from various machines. Learning algorithms are ideal for modeling the complex behavior of subjective parameters and identifying new hidden trends in perception and response. To that end, four learning algorithms – linear regression (LR), support vector machines (SVM), decision trees (DTs), and bagged DTs/random forests (BDTRF) – were used to construct models capable of predicting annoyance due to complex sound. Construction of these models relied on annoyance responses of 38 subjects to 103 sounds described by five predictors (loudness, roughness, sharpness, total tone prominence, and fluctuation strength).
Comparison of these models in terms of prediction accuracy, model interpretability, simplicity, and versatility indicates that BDTRF is the best algorithm for this task. The BDTRF learning algorithm is ideal for analysis and prediction of the annoyance of noise in close spaces such as habitable volume within a crewed spacecraft, module, or habitat, or other types of crewed enclosures used in a space environment. Here sample noise from such environments may be presented to a group of subjects and their response may be used to identify and rank predictors dominating annoyance or other responses of interest. This ranking is directly related to the physical design of sources (e.g., motors, fans, pumps, blowers) and habitable volumes, and may be used during design to precisely eliminate critical sound features responsible for the targeted response.

NIA and ODU Co-Sponsor Argument-Driven Inquiry Workshop
The National Institute of Aerospace (NIA) co-sponsored the Argument-Driven Inquiry workshop presented by Old Dominion University’s (ODU) Center for Educational Partnerships on Friday, October 4, 2019, at NIA. Representatives from ODU’s Center for Educational Partnerships included Dr. Joanna Garner, Executive Director, and Melanie Loney, Program Manager. Collaborating with NIA STEM Education Specialists, they introduced 14 teachers, STEM leaders, and NASA STEM education content creators from the Hampton Roads region to the evidence-based instructional model called Argument-Driven Inquiry (ADI). ADI is being used to teach science and engineering concepts and critical STEM literacy skills in K-12 classrooms. Workshop participants learned how in-school and out-of-school STEM experiences can be used to facilitate the formation of a robust STEM identity of students. This is achieved by implementing the nine stages of ADI for engineering to solve the challenge of designing a free-standing device that will convert potential energy to kinetic energy through the process of launching a mini marshmallow the farthest distance.

NIA Research Engineer Publishes Physical Review Fluids Journal Paper
Dr. Prahladh Iyer, Research Engineer at the National Institute of Aerospace (NIA), recently published a paper on wall-modeled large eddy simulation with NASA collaborator Mujeeb R. Malik in the Physical Review Fluids journal. The paper, “Analysis of the equilibrium wall model for high-speed turbulent flows,” was published July 25, 2019.
We perform a priori and a posteriori analyses of the equilibrium wall model for high-speed wall-bounded turbulent flows. The time-averaged flow from various direct numerical simulation (DNS) databases is used as input to the wall model and the accuracy of the predictions in terms of wall shear stress and wall temperature (or heat flux for isothermal wall boundary conditions) are assessed. Two different mixing-length-based eddy-viscosity models and various damping functions are tested in this study. Both mixing-length models involve two adjustable parameters: (i) the von Kármán constant κ, which varies in the literature from 0.37 to 0.44, and (ii) a viscous damping constant A+ (for the van Driest damping function). Also, for compressible flows, multiple scalings can be used for the viscous wall-normal spacing in the damping function.
The sensitivity of the results to these model parameters is reported, and it is found that the predictions of skin friction and wall temperature (or heat flux) are sensitive to the constants used, damping function scaling, and the wall-model exchange location. Wall-modeled large-eddy simulation (WMLES) is performed for (i) supersonic channel flow with a cold wall and (ii) an axisymmetric supersonic boundary layer for the adiabatic wall condition, to verify the a priori trends observed with respect to the damping functions.
A posteriori WMLES results are consistent with the trends observed in the a priori analysis of DNS data, thus indicating the usefulness of the a priori analysis. We introduce a damping function scaling, which works well over a range of Mach numbers and thermal wall conditions.

NIA BATAL Campaign Conducts Extensive Aerosol Measurements in India
With the last balloon flight scheduled for Aug. 1, the 2019 BATAL (Balloon measurement campaigns of the Asian Tropopause Aerosol Layer) campaign is nearing completion of data collection in India. BATAL 2019 has been a successful deployment with extensive measurements to study the composition and interplay between aerosols, clouds and trace gases in the upper troposphere and lower stratosphere during the Summer Asian Monsoon. With nine balloon flights–including payloads measuring aerosol, ice and trace gases from a few kilograms to 50 kilograms–the 2019 BATAL project is the most extensive balloon fieldwork in Asia. Data collected during the campaign will be used to validate satellite observations from CALIPSO and SAGE III/ISS.
NIA Senior Scientist Jean-Paul Vernier is supporting the research in India with Johnny Mau and Amit Pandit (NASA Langley Research Center). NIA Research Fellow Hongyu Liu will support the BATAL campaign by providing aerosol forecast using the GEOS-5 model.

NIA Research Fellow Co-organizes and Attends CMH-17/FAA/EASA Sandwich Disbond Workshop in Copenhagen, Denmark
Dr. Ronald Krueger, Associate Research Fellow at the National Institute of Aerospace (NIA), co-organized and attended a joint CMH-17-EASA-FAAWorkshop on Sandwich Disbonding held at the Technical University of Denmark (DTU) in Copenhagen, July 9-12, 2019. He gave a presentation CMH-17 Disbond Growth Team: Coordinated efforts to Address Sandwich Face Sheet/Core Disbondingand led the following discussion. He also presented High Fidelity Modeling of Face Sheet/Core Disbondingon behalf of Nelson Carvalho who could not attend the workshop. Profs. Leif Carlsson (Florida Atlantic University) and George Kardomateas (Georgia Tech) also presented results from the FAA funded project Study of Damage Modes in Lightweight Sandwich Structures Using Analysis and Testing.
During the workshop, an international group of 35 experts discussed face sheet/core disbonding in honeycomb sandwich constructions, which poses a threat to the structural integrity of a sandwich component but can be controlled through design, including damage tolerance principles, and maintenance procedures. This damage mode is of particular interest to the certification authorities such as the FAA and EASA since it was evident in several in-service occurrences, such as a rudder structural failure. Additionally, other control surface challenges, including lost strength and fluid ingression, have had relationships with disbonding. Past studies funded by the FAA and EASA have focused on face sheet/core disbonding which can lead to damage propagation caused by internal pressure changes in the core due to ground-air-ground cycles.
Sandwich structures are also common in rotorcraft and general aviation that do not fly at high altitudes. Further, sandwich monocoque structures have failed in a way that demonstrated the need to pay particular attention to disbond damage modes in single load path primary structure applications.
Future composite structure applications–for example, composite sandwich construction of the fuselage of business jets that experience higher altitudes than transport aircraft and new urban mobility vertical takeoff & landing aircraft products–are also driving a need to understand the phenomenon of disbond growth under generalized load conditions including advanced maneuvers and gust conditions.
To identify, describe and address the phenomenon, the Sandwich Disbond Growth Team was established as a group of experts within the CMH-17 Disbond and Delamination Task Group in 2011 following a similar workshop held at the National Institute of Aerospace. The Composite Materials Handbook (CMH-17)creates, publishes and maintains proven, reliable engineering information and standards, subjected to thorough technical review, to support the development and use of composite materials and structures. Currently, the group is working to identify sandwich structural design details where sandwich disbonds initiate and other real structure scenarios, which may promote growth. The goals of such studies are to evaluate potential sandwich disbonding and establish design guidelines that eliminate the growth potential or, at least, minimize the effect on structural integrity. The ultimate goal is to develop and provide tools to minimize sandwich disbonding and help mitigate any safety-related concerns.
Stakeholders in this activity are the certification authorities, original equipment manufacturers, suppliers, universities as well as government research facilities and associated contractors.

NIA Samuel P. Langley Professor Co-Edits Book
Prof. Dimitri Mavris, National Institute of Aerospace (NIA) Samuel P. Langley Professor at Georgia Tech, has co-edited the book Complex Systems Engineering: Theory and Practice, which was recently published by AIAA. This book represents state-of-the-art thought leadership on system complexity for aerospace and aviation. The costs and consequences of current knowledge and practice gaps are substantial. These problems are caused by several factors: the lack of human capacity to comprehend complexity without machine/autonomation interfaces, the rapid pace of changes in the sector, and the increasing complexity and complicatedness of systems of all types and sizes (occurring by design and by default).
As large organizations like NASA LaRC work to advance their missions in the face of increasing complexity and challenges, this book provides critical strategies and paradigms. The breadth of topics covered by this book was selected to provide an enriched view of all types of systems—technical, machine, and human systems.

The conference was attended by about 625 participants from 386 companies and 36 different countries. Dr. Krueger currently chairs the NAFEMS Composites Working Group and chaired one of three special sessions on composites during the conference. He also presented a paper A Benchmark Example for Delamination Growth Predictions Based on the Single Leg Bending Specimen under Fatigue Loading co-authored with Lyle Deobald and Haozhong Gu of The Boeing Company. This work had been accomplished as part of NASA’s Advanced Composites Project (ACP).
Analysis benchmarking is used to evaluate new algorithms for automated VCCT-based delamination growth analysis. First, existing benchmark cases based on the Single Leg Bending (SLB) specimen for crack propagation prediction under quasi-static loading are summarized. Second, the development of new SLB-based benchmark cases to assess the static and fatigue growth prediction capabilities under mixed-mode I/II conditions is discussed in detail. Additionally, a scheme is proposed to interpolate between known fatigue delamination growth rates to obtain values for mixed-mode ratios for which data has not been defined in the input. Further, a comparison is presented, in which the benchmark cases are used to assess new analysis tools in ABAQUS/Standard FD03. These recently implemented tools yield results that are in good agreement with the benchmark examples. The ability to assess the implementation of new methods in one finite element code illustrates the value of establishing benchmark solutions.

NIA Senior Research Scientist Presents New UAM and UA Vehicle Concept
There are many plans to use flying vehicles for various tasks in urban environments. One major concern about these plans is the anticipated impact of noise by these vehicles on the public. These concerns motivate the need for better assessment of noise and its impact on the public, preferably under controlled reproduction conditions.
Menachem Rafaelof, a Senior Research Engineer at the National Institute of Aerospace (NIA), recently presented a new concept for high fidelity synthesis and reproduction of noise by UAM and UA vehicles to members of the Structural and Aeroacoustics branches at NASA Langley. High fidelity synthesis of sound is essential to accurately gauge its impact on observers, a critical task in the process to improve the design and operation of these vehicles. Acoustic Transfer Function (ATF) relates sound pressure at a point in space to a set of overall input control efforts, under time-invariant conditions, representing excursions from vehicle’s trim state.

NIA Associate Fellow Attends CMH-17 and ASTM Committee Meeting
Dr. Ronald Krueger, Associate Fellow at the National Institute of Aerospace (NIA), travelled to Salt Lake City, UT to attend the joint CMH-17 (Composite Materials Handbook) ASTM Committee D30 meetings (March 11-15, 2019). The Composite Materials Handbook creates, publishes and maintains proven, reliable engineering information and standards, subjected to thorough technical review, to support the development and use of composite materials and structures. Therefore, experts from the field periodically meet to discuss critical technical issues for composite structural applications. Stakeholders in this activity are the certification authorities (FAA, EASA), industry, academia and government research facilities.
It is envisioned that in the future CMH-17 will be the authoritative worldwide focal point for technical information on composite materials and structures. It is planned that lessons learned during NASA’s Advanced Composites Program (ACP) will be published in revision H of CMH-17.
Dr. Krueger participated in technical meetings of the Safety Management, Testing, and Sandwich Working Groups as well as the Damage Tolerance Task Group. He chaired a meeting of the Disbonding and Delamination Task Group (DDTG), which determines an overall strategy for the handbook to address disbonding and delamination of composites and examines methodologies needed to assure through-thickness integrity of bonds and laminations in polymer matrix composites.
The meeting focused on new items, which are envisioned for inclusion in the upcoming revision H of the handbook. Currently, it is expected that revision H will be published in the 2021/2022 timeframe. New items include the addition of fracture toughness data to Volume 2, the addition of a chapter on cohesive zone modeling for disbonding/delamination analysis and a new chapter on disbonding/delamination arrest methods such as stitching, Z-pinning and rivets.
Dr. Krueger also organized a four-hour focused working meeting of the Sandwich Disbond Growth Teamin parallel to the CMH-17 main meetings. The Sandwich Disbond Growth Teamwas established as a group of experts within the CMH-17 Disbond and Delamination Task Groupin 2011 to identify, describe and address the phenomenon of sandwich face sheet/core disbonding. This failure mode is of particular interest to the FAA from their perspective of Continued Operational Safety (COS) since several in-service occurrences have been observed which can pose a threat to the structural integrity of an aircraft or spacecraft component.
The focus of the meeting was to review the status of the current research performed in the US and Europe. Further, standardizing the Single Cantilever Beam (SCB) test as an ASTM standard was discussed and a path towards an additional ASTM test procedure for fatigue testing was developed. Additionally, new draft sections, which have been submitted for inclusion in the upcoming revision A of CMH-17 Vol. 6 were discussed.
Dr. Krueger also attended the bi-annual meeting of ASTM committee D30 on Composite Materials. This ASTM committee develops standard test methods, practices, terminology, and guides pertaining to composite materials. Stakeholders for the work include certification authorities, industry, academia, and government research facilities. Dr. Kruegercurrently serves as the chair of the committee and led the meetings of the executive and main committees.

Samuel P. Langley Professor, NIA Researchers and NASA Langley Researchers Collaborate on RVLT Project Milestone
In Jan. 2019, NIA Senior Research Engineer, Li Wang, NIA Research Fellow, Boris Diskin and a University of Maryland group led by NIA Samuel P. Langley Professor, Olivier A. Bauchau, in collaboration with NASA LaRC researchers from FUN3D and ANOPP2 development groups completed a milestone (RVLT.23.01.L313– Aero, Acoustic, Structural Adjoint Developed) of the NASA Revolutionary Vertical Lift Technology (RVLT) Project (Program Manager Susan A. Gorton).
The milestone required implementation and verification of the discretely-consistent adjoint-based sensitivity analysis for high-fidelity multidisciplinary rotorcraft simulations coupling three disciplines, computational fluid dynamics (CFD), rotorcraft comprehensive analysis (CA), and acoustic prediction models. Adjoint-based sensitivity analysis is an enabling technology that allows efficient computations of sensitivity of a few objective functions to many design parameters. In this demonstration, an adjoint-capable CFD code, (FUN3D) has been coupled with a nonlinear, flexible, multibody-dynamics CA solver (DYMORE), and an acoustic prediction and noise propagation code (ANOPP2) that also provide sensitivity analysis capabilities.
Systematic verification of the adjoint-based high-fidelity multidisciplinary FUN3D/DYMORE/ANOPP2 sensitivity analysis has been conducted using an isolated 4-blade HART-II rotor. The accuracy of the sensitivity analysis has been verified by comparing with the sensitivities computed by the complex-step method. The complex-step method can provide exact sensitivities for an individual design parameter. The ANOPP2 objective function used for the verification studies is the summation of acoustic pressures at a single observer location, which is set about 35 radii away from the rotation center. Design parameters include shape parametrization and kinematics trim parameters consisting of collective and cyclic pitch control angles.
The agreement between the adjoint-based sensitivities and the complex-step sensitivities is good: 12-13 digits agree for shape design variables, and 10-11 digits agree for kinematics trim design variables. Successful verification of the multidisciplinary adjoint-based sensitivity analysis for a rotorcraft system that couples high-fidelity aerodynamics, rotorcraft comprehensive analysis, and acoustics models meets the requirements for the Level 3 Milestone RVLT.23.01.L313 and represents an important step toward a low-noise rotorcraft design based on high-fidelity multidisciplinary simulations

NIA Research Scientist Presents Paper at AIAA SciTech 2019
Ivan Perez, Research Scientist at the National Institute of Aerospace (NIA), presented the paper entitled “Formal Verification of System States for Spacecraft Automatic Maneuvering,” co-authored by K. L. Hobbs (Air Force Research Laboratory), A. Fifarek (LinQuest Corporation), E.M. Feron (Georgia Institute of Technology). AIAA SciTech Forum 2019 was held Jan. 7-11, 2019 in San Diego, CA.
As the complexity and number of space operations in Earth orbit continue to grow, there are increased opportunities to incorporate automatic or autonomous maneuvering as part of a space traffic management framework. Understanding the context of the automatic maneuver, including the conditions under which an automatic maneuver is acceptable, is important to the design of the overall automatic maneuver system.
This work proposes and conducts formal verification of high-level system requirements to govern automatic maneuvering of satellites in the presence of safety interlocks or failures. Three examples of automatic maneuver contexts are considered: conjunction avoidance, especially in the presence of orbital debris; rendezvous and proximity operations, especially for service satellites and active debris removal; and station keeping, especially in large satellite constellations providing space-based services like the Internet.
The primary contribution of this paper is the development and analysis of formal requirements for high-level system states governing when an automatic maneuver is acceptable. The requirements serve as a baseline framework for future automatic spacecraft maneuver research.

NIA Senior Research Engineer Completes Implementation of Inviscid Scheme into NASA’s FUN3D Code
Yi Liu, Senior Research Engineer at the National Institute of Aerospace (NIA), has completed the implementation of a low-dissipation Roe flux and a third-order inviscid scheme into NASA’s FUN3D code. This work has been funded by the NASA Aeronautics Research Mission Directorate Transformative Aeronautics Concepts Program Transformative Tools and Technologies project under Contract No. NNL09AA00A with Hiro Nishikawa as co-PI. These new capabilities will be available for use by general users with the next software release. The third-order low-dissipation inviscid scheme enables time-dependent vortical flow simulations with much higher resolution than the default method. These improvements have been achieved at a surprisingly small additional cost. The low-dissipation flux is a very simple modification to the existing flux and requires almost no additional computing time. The third-order scheme is a very economical edge-based scheme and requires only 15% additional computing time to achieve higher-order for inviscid dominated flows.

NIA Research Fellow Presents Sandwich Research at Denmark Technical University (DTU) in Copenhagen, Denmark
Dr. Ronald Krueger, Associate Research Fellow at the National Institute of Aerospace (NIA), traveled to Copenhagen, Denmark, June 20 to visit Denmark Technical University (DTU) and present a technical overview on Face Sheet/Core Disbonding in Sandwich Composite Components: A Road Map to Standardization co-authored with James Ratcliffe (NASA LaRC) and Zhi M. Chen (FAA, Tech Center, Atlantic City). Sandwich face sheet/core disbonding is a failure mode which is of particular interest to the FAA from their perspective of Continued Operational Safety (COS) since several in-service occurrences have been observed which can pose a threat to the structural integrity of an aircraft or spacecraft component.
To address this problem, test and analysis methods need to be developed. Recently, DTU was one of seven research laboratories in the US and Europe that participated in an international round robin activity to evaluate an ASTM Draft Standard for Interfacial Fracture Toughness of Peel Loaded Sandwich Constructions. NASA Langley also supported this standard development initiative through direct authorship of the draft standard and test protocol and participation in the round robin testing. NIA continues to support this activity through an FAA grant Study of Damage
Modes in Lightweight Sandwich Structures Using Analysis and Testing in collaboration with Florida Atlantic University (FAU) and Georgia Tech (GT). FAU has been a close partner with DTU on this topic for an extended period of time.

NIA Associate Research Fellow Publishes Manuscript in Journal of the Air & Waste Management Association
The manuscript titled “Development of the crop residue and rangeland burning in the 2014 National Emissions Inventory using information from multiple sources” was published by George Pouliot, Venkatesh Rao, Jessica L. McCarty & Amber Soja in the Journal of the Air & Waste Management Association, DOI:10.1080/10962247.2016.1268982. This manuscript uses NASA’s Earth Observations to enhance fire emissions at the Environmental Protection Agency.
Abstract: Biomass burning has been identified as an important contributor to the degradation of air quality because of its impact on ozone and particulate matter. One component of the biomass burning inventory, crop residue burning, has been poorly characterized in the National Emissions Inventory (NEI). In the 2011 NEI, wildland fires, prescribed fires, and crop residue burning collectively were the largest source of PM2.5.
This paper summarizes our 2014 NEI method to estimate crop residue burning emissions and grass/pasture burning emissions using remote sensing data and field information and literature-based, crop-specific emission factors. We focus on both the postharvest and pre-harvest burning that takes place with bluegrass, corn, cotton, rice, soybeans, sugarcane and wheat.
Estimates for 2014 indicate that over the continental United States (CONUS), crop residue burning excluding all areas identified as Pasture/Grass, Grassland Herbaceous, and Pasture/Hay occurred over approximately 1.5 million acres of land and produced 19,600 short tons of PM2.5. For areas identified as Pasture/Grass, Grassland Herbaceous, and Pasture/Hay, biomass burning emissions occurred over approximately 1.6 million acres of land and produced 30,000 short tons of PM2.5.
This estimate compares with the 2011 NEI and 2008 NEI as follows: 2008: 49,650 short tons and 2011: 141,180 short tons. Note that in the previous two NEIs rangeland burning was not well defined and so the comparison is not exact. The remote sensing data also provided verification of our existing diurnal profile for crop residue burning emissions used in chemical transport modeling. In addition, the entire database used to estimate this sector of emissions is available on EPA’s Clearinghouse for Inventories and Emission Factors (CHIEF, http://www3.epa.gov/ttn/chief/index.html).
Implications: Estimates of crop residue burning and rangeland burning emissions can be improved by using satellite detections. Local information is helpful in distinguishing crop residue and rangeland burning from all other types of fires.
NIA Associate Research Fellow Revises and Submits Paper to Earth Environment Research Letters
The paper, “Long-term radiation budget variability in Northern Eurasia: Potential for assessing current and future fire season variability” revised by Dr. Paul Stackhouse and Dr. Amber Soja was submitted to the Earth Environmental Research Letters on January 20, 2017. This paper composes a long-term (30-year) surface radiation fluxes by scaling and normalization of two different satellite-based data sets. The normalization is then assessed using extended measurements from surface solar flux measurements distributed throughout the Russian area of the NEESPI region. Decadal averaged long-term shifts of the radiative fluxes using these data compared favorably to changes in fire-related meteorological indexes using a reanalysis and actual fire occurrences. Stackhouse and Soja added a case study to this paper to better show the correspondence on the short-time scale as well. This paper is intended to be included in the NEESPI special issues that are being built out through ERL. Additional co-authors included J. Colleen Mikovitz, Dr. Taiping Zhang, and David Westberg of SSAI/NASA LaRC and Dr. Anatoly Tsvetkov of Voeikov Main Geophysical Observatory (MGO) in St. Petersburg, Russia.
