Description

Memorandum presenting an investigation of the dynamic stability of the Bell X-5 research airplane at 58.7 degrees sweepback and at altitudes of 40,000 feet and 25,000 feet over a Mach number range of 0.5 to 0.97. The results show that the longitudinal oscillatory motions are well damped over the entire Mach number range except for residual oscillations resulting primarily from engine gyroscopic coupling with the lateral oscillatory mode. The longitudinal and lateral frequency-response characteristics were obtained and some coupling effects were noted.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
