The device comprises an inflatable bag (1) attached to the underside (2.1) of the body of the helicopter (2), its upper portion being shaped to fit the whole of the underside (2.1) of said helicopter. When inflated and ready for use, said bag has the shape of a very large trapezoid and extends well beyond the space occupied by the helicopter itself, increasing the lift polygon. The sides of said bag are provided with anti-buckling reinforcing elements (4), and devices (3) for limiting controlling internal pressure.
