发明名称 VOILURE SOUPLE POUR UN PARACHUTE OU POUR UN APPAREIL DESTINE AU VOL DE PENTE, AU VOL ASCENSIONNEL OU AU VOL MOTORISE
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.
