Abstract
An improved thermodynamic drive which accelerates exhaust gases through a convergent-divergent exhaust nozzle (14) from a high pressure combustion chamber 12 to an ultra high velocity and by entraining atmospheric air therein; transfers a portion of the inertia from those exhaust gases to the atmospheric air flowing through an atmospheric air nozzle 16. Cool water is injected by water injectors (25) into the flow of air which is isothermally compressed by rapidly decelerating into a high pressure water separator (28). The water separator separates water condensed from the air by the compression and water cooling, and also the water injected into the air. Some of this water is cooled in a heat exchanger (30) and re-injected into the air flowing through the atmospheric air nozzle for cooling the compression. The remainder of the water is mixed with the fuel by mixer (35). The fuel/water mixture is pumped by fuel pump (42) at a high pressure into a fuel vaporizer chamber as a mist and vaporizes before passing into a fuel/water superheater (48). The fuel/water vapor is injected by fuel injector ( 52) through combustion chamber inlet (13) into the combustion chamber (12) to complete the cycle. The water in the fuel and the vaporizer chamber prevent carbon deposits in the system. The fuel vapor injection further compresses the intake air into the combustion chamber. A standing wave may be used to further compress the air.
