摘要： The present invention provides closed-circuit hydraulic thruster used for the generation of thrust, or lift, force from the torque provided by a prime mover, or a motor. In a preferred embodiment the closed-circuit hydraulic thruster comprises an outer casing; at least two inner-members; at least one intermediate body; a drive shaft; at least one rotor assembly including a central disk and a plurality of circumferentially arranged, low angle of attack, hydrofoil-like blades; and an incompressible fluid completely filling the space enclosed within the casing. In operation, the incompressible fluid will circulate within the passages confined between the opposing surfaces of the casing, inner- members, and intermediate body due to its acceleration by the rotor blades, with the blades' generated thrust force being transmitted to the thruster' s casing through thrust bearing arrangement(s) Means for cooling the incompressible viscous fluid are also provided.

摘要： The present invention provides closed-cycle hydro-jet thruster (CCHJT) used for the direct conversion of torque into thrust and/or lift force. In a preferred embodiment, the CCHJT includes an outer casing; two inner-members; an intermediate body; a plurality of convergent nozzles; a set of intersecting members; a drive shaft; a rotor assembly having a plurality of blades; a hydraulic fluid completely filling the space within the casing; and a fluid pressure regulating system. In operation, the rotating blades accelerate and compress the hydraulic fluid leading to generation of thrust/lift force on the blades, which is transmitted to the CCHJT's casing through thrust bearings. This is followed by acceleration of the working fluid within the nozzles, suddenly expanding the accelerated working fluid within sub-passages defined in-between the intersecting members, and then directing the flow of the working fluid towards the upstream suction surfaces of the blades for re-acceleration.
