NIA Researcher Honored by AHS

Dr. Boris Diskin, Associate Research Fellow at the National Institute of Aerospace, and his NASA LaRC collaborator, Dr. Eric Nielsen, were recognized by the American Helicopter Society (AHS) for their contributions to formal optimization using computational fluid dynamics for rotorcraft. Their paper, “Discrete Adjoint=Based Design for Unsteady Turbulent Flows on Dynamic Overset Unstructured Grids”, published in 2013, was the first such publication for this complex rotorcraft challenge. AHS determines the most noteworthy and significant contributions made in both the theory and practice of helicopter and other VTOL aircraft technology at designated vertical flight historical sites around the world. Significant events cited by the AHS for Langley include the creation of NACA, the building of the Langley Memorial Aeronautical Laboratory, the building and operation of selected wind tunnels, and the design and test of specific rotorcraft. Diskin’s paper, however, is only the second publication to receive such recognition since 1915. The AHS International Vertical Flight Heritage Site Recognition Ceremony was held at NASA Langley on May 8, 2015.
