A flight investigation of the spinning of the NY-1 airplane with varied mass distribution and other modifications, and an analysis based on wind-tunnel tests
This is a 1934 NACA technical report by NASA's Technical Reports Server, a flight investigation of spinning in the NY-1 airplane with varied mass distribution, backed by wind-tunnel analysis, written for aeronautical engineers. Its three charts plot pitching-moment and rolling-moment coefficients against angle of attack for aerodynamic and gyroscopic moments across spin-related conditions, with curves that rise to sharp peaks and then taper, giving a designer little beyond graph-paper line structure, grid patterns, and bold black curves on white.
