  • External airbag protection system for helicopters
    Patent number: 5992794
    Abstract: An airbag protection system for helicopters. Airbags are inflated either automatically or manually, or a combination of both, prior to the helicopter striking the ground, thus avoiding or ameliorating a crash. Proximity sensors detect a fast descent to trigger inflation of the airbags located beneath the helicopter fuselage so that they can cushion the impact with the ground. Venting of the gas from the airbags is also provided to release the gas from the airbags so as to prevent rebound of the helicopter from the ground.
