Improved Thrust Expansion Engine.
Abstract
In accordance with the present invention one or more methods are utilized to suppress the break up of water columns flowing through helical channels in the rotor of a thrust producing engine propelled through the water so as to avoid the resultant increase in cooling rate of hot propellant gas. The rotor of such an engine is in slide bearing contact at its forward axial end with a bearing portion of the engine block projecting from an annular face thereon. Radially extended, inflow blocking formation of the engine block terminating at said annular face are in abutment with an axial end of the rotor at which the inlet ends of the channels are located so as to cyclically control intake and filling of the channels with columns of water directed thereto between the aforementioned radial inflow blocking formations of the engine block.
