The Conceptual Design and Research on New Air-Water Engine

In order to realize the air-water engine, a new multi-bypass amphibious engine conceptual design is proposed. The situation of air mode is analyzed briefly based on the establishment of a three dimensional finite element model. The situation of water mode is analyzed and calculated, and determines the metal sodium as the fuel of the reaction of metal and water. The relationships of fuel flow, combustion chamber pressure, thrust, fuel flow rate and specific impulse are obtained. The suitable range of fuel flow rate is preliminarily determined and the effect of propulsion of water mode is affirmed. The simulation of the design parameters of the metal-water reaction engine is conducted with CFD software. The parameter which is the most advantageous to metalwater reaction and the propulsion effect of the metal-water reaction engine is determined. Preliminarily evaluating the design goal of the new air-water engine is achieved.
