英文摘要： The water and air amphibious aircraft can fly in the sky, voyage on the sea and dive into the water. Therefore, it can better satisfy our desire to fly and in the meantime has tremendous potential applications to both the army and the civilians. However, the propulsion system has to be able to work in both the air and water environment, which poses a technical challenge in need of innovative solutions since it is beyond the reach of currently available propulsion systems. This project adopts the combination of theory analysis, analog simulation and experiments in order to explore the impact of air and water fluid behavior on the operating and component design of the propulsion system. The project aims at discovering the designing law for propulsion systems with the capability to work in both the air and water, or searching for the modulating control methods which are simple and efficient. On this basis, by using two different technical routes of seeking common ground while reserving differences, and applying the mechanical innovative methods of association and combination, this project makes innovative design for the propulsion systems of the water and air amphibious aircraft, and proposes creative resolutions and conducts deep analysis and optimization. The research focus on the various working medium cycle ana
