  • Airplane landing gear suspension and shock-absorbing device
    Patent number: 6609682
    Abstract: A shock absorber that uses polyurethane discs for aircraft landing gear. The discs are maintained under compression. When the aircraft lands or taxis, loads further compress the discs. Unlike bungee cords, however, the discs do not release their energy immediately. Rather, they release the energy slowly, which produces a smoother reaction to loads that eliminates any bounce back of the aircraft.
    Type: Grant
