Stability of Castering Wheels for Aircraft Landing Gears, Special Report
This is a 1937 NACA special report on the stability of castering wheels for aircraft landing gears, published by the National Advisory Committee for Aeronautics for engineers and aircraft designers. The pictures are plain photographic plates: a test-rig wheel photographed in sequence, numbered frame strips of the wheel rolling and shimmying, a model landing gear shot from above, and graphs of experimental and theoretical frequency and divergence against velocity, offering a designer reference for mechanical motion and test data rather than decorative imagery.
