ABSTRACT:
The invention relates to a device for increasing the stability, especially the lateral stability, of a helicopter placed on board (1) 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 the axis of which 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.
Application to the equipment of helicopters placed on board, having a tricycle landing gear.
