A Flight Investigation of the Spinning of the F4B-2 Biplane with Various Loads and Tail Surfaces
This is a 1936 NACA technical report from the NASA Technical Reports Server, a flight investigation of spin behaviour in the US Navy F4B-2 biplane fighter under varied loads and tail surfaces, written for aeronautical engineers. The photographs show the aircraft with markings and tail configurations, and the chart plots angular velocity, load factor, altitude and control positions against time during a spin, useful for designers wanting technical plate layouts with grid-based data graphics.
