NASA Ames Research Center, Moffett Field, CA is the NASA lead Center for
rotorcraft research. Rotorcraft research at Ames includes system analysis and
configuration optimization, aeromechanics, and flight control and cockpit
integration. Research in other areas such as composite structure and material,
and rotor acoustics are conducted mainly at Langley Research Center, and
rotorcraft propulsion and drivetrain are conducted at Lewis Research Center.
This seminar will discuss Ames' rotorcraft research goals and some sample
research projects and results. The talk will also briefly describe the newly
formed Army/NASA Rotorcraft Division, which combines the resources of rotorcraft
branches in NASA Ames Aeronautics Directorate with Army's Aeroflightdynamics
Directorate to better achieve the missions of the two previous rotorcraft
research organizations at Ames.
Rotorcraft research activities at NASA Ames are funded by two main program categories: Research and Technology (R&T) Base program and the Short Haul (Civil Tiltrotor) program. Work in the R&T program is carried out by the research staff in the Army/NASA Rotorcraft Division, and the work on SH(CT) program is carried out jointly by the SH(CT) program office and the Army/NASA Rotorcraft Division. Sample research projects and results in R&T base program, such as conceptual assessment of several high-speed rotorcraft, rotorcraft CFD, individual blade control for reduction of external noise and vibration, noise-abatement flight procedures, engine inoperative procedures, handling qualities, and advanced flight control laws are broadly reviewed. High-speed rotorcraft research related to SH(CT) technology development conducted at Ames in the areas of low-noise proprotor, and low-noise terminal-area operations is also discussed.
