FLEXIBLE WING FOR A PARACHUTE OR AN APPARATUS FOR SLOPE FLIGHT, ASCENT FLIGHT OR MOTORIZED FLIGHT

摘要

Parachute wing with a particularly performing aerodynamic configuration and capable of keeping such configuration when the flight conditions are disturbed. The wing (1) comprises open cells (6) which are open at the leading edge and closed at the trailing edge (2), and closed cells (13) which are swollen from the open cells. The ribs (16) separating these two types of cells have air inlet orifices (17) which are provided with anti-return valves. Thus, the closed cells (13) remain swollen and keep their configuration if the pressure drops in the front openings (14) of the open cells. Furthermore, their leading edge (15) may have an appropriate shape and their profile may be thinner than that of the open cells. The invention is applicable to parachutes or crafts for hill flight, climbing flight or even motor flight.
