摘要
Airplane gear legs must be strong, stiff, and capable of storing large amounts of energy. Present gear legs are very heavy. These improved gear legs use two composite materials. The first is very strong and flexible, allowing it to store a great deal of energy in a hard landing. These fibers are laid essentially parallel to the axis of the gear leg. The other fiber is very stiff, providing the torsional rigidity necessary to avoid flutter. The stiff fibers are laid at a large angle to the axis of the gear leg so their elastic limit is not exceeded during a hard landing.
