mounted in a water channel of the boat hull and composed of an engine, a transmission shaft driven by the engine, an impeller driven by the transmission shaft and provided with blades, a stator mounted behind the impeller and provided with stator vanes, and a nozzle located behind the stator...
[Class 51 (i)] [Also in Groups XXVI; XXVII, XXVIII and XXXIII] In a jet-reaction propelling unit of the kind wherein intermittent explosions occur in a ball shaped combustion chamber the inertia of the issuing gas in the ejector tube is used to scavenge the combustion chamber and to ...
The nozzles, which are in fluid connection with the impeller 34 via channels through the housing 8 that are located in a different plane than the one shown in the figure, point in such directions that the jet may be used to lower the forward speed of the watercraft or propel it in the...
engine and the said storage tank, steering pipe members arranged longitudinally of the bow of the vessel below the water line and having angular ends passing through the said bow and stern of the vessel, valves upon the said angular ends, oppositely disposed nozzles in the said pipes, valve ...
Hereby it is achieved that the jet maintains its cross section when leaving the nozzle so that the thrust works solely in the axis direction. Furthermore, the ratio of the energy level (pressure and velocity) on the intake side to the energy level (pressure and velocity) on the exit side...
A jet pipe 14 has a main variable-area propelling nozzle 16 formed at its downstream end. The engine and jet pipe are enclosed with a nacelle 38 which defines a by-pass passage 18 supplied with air from the engine compressor. A second variable-area nozzle 20 is provided at the downstream...
[Also in Division B7] A jet engine for use in aircraft capable of vertical take-off and landing comprises a rearwardly-directed propulsion nozzle and a downwardly-directed lifting nozzle, the two nozzles branching from a common duct from which by means of a suitable distributing device, gas...
A nozzle for a hypersonic engine includes an axially displaceable mushroom-shaped central body. Two mutually opposing expansion flaps are provided which, when the flying Mach number is low, can be swivelled with respect to one another and, when the flying Mach number is high, can be swivel...
