ABSTRACT:
A shoe pad for helicopter landing gear skids is formed of an elongated, flattened, narrow, thin wall steel channel which is inverted so that it opens downwardly. The channel is filled with a matrix of hard metal carbide and a binder of soft, ductile, somewhat resilient, cuperous metal. The base of the channel is welded to a shoe strip which is fastened to the bottom surface of a skid. The exposed matrix contacts the ground in landings and take-offs, and tends to absorb impacts, reduce drag friction with the ground and dissipate friction caused heat, thereby materially reducing skid and skid shoe damage and wear.
