Abstract (en)
[origin: EP0317431A1] Ship equipped with at least one jet propeller, consisting of a casing containing, between an inlet (3) tangential to the hull (2) and a rear water outlet (4), an upstream duct (5), a pump wheel (6), fixed straightening blades (7) and a hub (8) carried by the blades which forms, with the casing (9), an outlet nozzle (10). <??>The cross-section of the outlet nozzle (10) varies within small limits between the blades (7) and the outlet (4) by virtue of pipes (25, 26, 29) for injecting gas into the nozzle (10), which pipes are arranged in the vicinity of the downstream edge of the blades (7) and are connected by a circuit to means for supplying compressed air (16). The supply circuit comprises an outer annular housing (14) formed around the blades (7) in the casing and connected to the injection pipes (25, 26, 29). <??>Application to ships requiring a very high thrust. <IMAGE>
