Momentum propulsion for ship propulsion is almost noiseless whereby physics for rotary piston pump is enabled through machine concepts

摘要

Momentum propulsion is almost noiseless for the propulsion of submarines. The physics for the rotary piston pump is enabled through machine concepts. The pulsed current is produced not by propeller or impeller as compared to that in conventional ship propulsion by marine propeller and jet propeller, but through a continuous and smooth displacement on a circular path.
