Nhan Nguyen Gives Invited Talk on Perfromance-Adaptive Aerolastic Wing Research at NASA

Nhan Nguyen gave an invited talk at Bombardier Aircraft Flight Test Center in Wichita, Kansas, on July 24, 2017. The title was entitled, “Performance-Adaptive Aeroelastic Wing Research at NASA”. The talk highlighted several elements of research being conducted under the NASA Advanced Air Transport Technology (AATT) project, including Ames-developed Variable Camber Continuous Trailing Edge Flap (VCCTEF) technology, and the aeroelastic wing-shaping control technologies for drag optimization, flutter suppression, and gust-load alleviation. The talk was attended by more than 20 people and several more online. Bombardier discussed some potential areas of interest including the VCCTEF. During the visit, Bombardier also gave a tour to show their flight test certification program for their avionic systems, and their latest C series production commercial aircraft currently under preparation for flight certification testing.

BACKGROUND: The Advanced Air Transport Technology (AATT) project conducts research and development of advanced transport aircraft technologies for improved fuel efficiency and reduced noise and emissions. Under this project, NASA Ames is conducting research and development of performance of adaptive aeroelastic wing-shaping control technology for future flexible high aspect-ratio wing-transport aircraft. This technology addresses drag optimization and aeroservoelastic multi-objective flight control, including flutter suppression and load-alleviation control. The project develops multidisciplinary modeling and simulation capabilities in order to support this technology development. Current aircraft, such as the Boeing 787 and Airbus A350, have already employed some limited capabilities of their own adaptive aeroelastic wing-shaping control technologies. This Ames-developed technology can further contribute to the goals of improved fuel efficiency and safe operation of current and future passenger aircraft with flexible high aspect-ratio wing design.
