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
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.

A device for increasing the stability of a helicopter having a tricycle landing gear (2, 6) constituted by two main and lateral undercarriages (6) and one auxiliary undercarriage (2) when said helicopter is set down on a moving platform, said device comprising an auxiliary stabilizing gear operative
A device for increasing the stability of a helicopter having a tricycle landing gear (2, 6) constituted by two main and lateral undercarriages (6) and one auxiliary undercarriage (2) when said helicopter is set down on a moving platform, said device comprising an auxiliary stabilizing gear operative only when said helicopter is landing with a rotor thereof rotating or stopped, said stabilizing gear comprising at least two lateral stabilizers (13), each of said lateral stabilizers comprising a rigid support (17, 27) having an end part which supports at least one stabilizing wheel (16) for contact with said platform, said rigid support (17, 27), at least in position of use, being integral with a stable structure of said helicopter at a lower part of a fuselage (1) of said helicopter, said rigid supports being offset laterally one on each side of a vertical and median longitudinal plane (PP) of said helicopter, in the direction turned towards an auxiliary undercarriage (2) in relation to said main and lateral undercarriages (6) of said tricycle landing gear, in such a manner that said at least one stabilizing wheel (16) is supported on said moving platform, on both sides of said longitudinal and median plane of said helicopter (PP) when said helicopter rests on said platform with said tricycle landing gear (2, 6).
