Device for increasing the stability of helicopters placed on board and set down, having a tricycle landing gear, and helicopter equipped with such a device

摘要

Device for increasing the lateral stability of a helicopter having a tricycle landing gear (2, 6), when it is set down on a moving platform. The device comprises two lateral stabilizers (13), each equipped with a wheel (16) for support on the platform and connected to the structure of the helicopter by an essentially rigid support, comprising a leg (17), about whose axis the wheel (16) can turn, the leg (17) itself being connected to the structure by a rigid and transverse component which may be a pivot axle if the leg can be raised, or a slidingly fitted arm if the stabilizer (13) is additional. The stabilizers may also be integrated into a towing trolley.
