Airplane landing gear
This is a 1931 NACA technical memorandum on airplane landing gear, issued by the National Advisory Committee for Aeronautics for aeronautical engineers and designers. Its pictures are numbered line drawings of undercarriage parts, including wheels, struts, shock absorbers, brake assemblies and hydraulic fittings, shown in plan, section and elevation with leader lines and dimension marks, offering a designer clear mechanical diagrams of early aircraft gear.
