Abstract

The invention discloses a supersonic rotor engine, which comprises a supersonic jet channel (1), a rotating structure body (2) and a high pressure working medium source (3), wherein the supersonic jet channel (1) is formed on the rotating structure body (2); a working medium inlet (1001) of the supersonic jet channel (1) is communicated with the high pressure working medium source (3); the loading capacity of the high pressure working medium source (3) is higher than 2MPa; the jet of the supersonic jet channel (1) is generally oriented by a tangent line of rotating circumferential of the rotating structure body (2); and the rotating structure body (2) externally outputs power. The supersonic rotor engine has a simple structure, low manufacturing cost and high reliability, and greatly improves the efficiency of conventional engines.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a rotary engine. Background technique [0002] Whether it is a piston or a turbine engine, its structure is relatively complicated and its efficiency is not high. And the supersonic jet channel body (such as rocket nozzle, etc.) as the thrust engine can convert thermal energy into the kinetic energy of supersonic gas with very high efficiency, as long as the motion speed of the supersonic jet channel body is high enough, very high energy can be obtained. High propulsion efficiency, when the moving speed of the supersonic jet channel body is close to the moving speed of the supersonic gas ejected from the supersonic jet channel body, all the kinetic energy of the supersonic gas can be completely transformed into the supersonic jet channel body The sum of the energy of the kinetic energy and the work done by the body of the supersonic jet channel. This thermal power system...

AI Technical Summary

Problems solved by technology

This thermal power system is simple in structure and high in efficiency, but the supersonic jet channel body is difficult to use as an engine that outputs rotational power, because when the supersonic jet channel body rotates at a high linear speed, a huge centrifugal force will be generated, and the current It is difficult for some materials to withstand this huge centrifugal force

If the supersonic jet channel body cannot be made to perform circular motion at a high linear velocity, only a part of the kinetic energy of the gas ejected from the supersonic jet channel body will be changed into the kinetic energy of the supersonic jet channel body and what the supersonic jet channel body does to the outside. work, while the other part or even most of it still exists in the gas as the kinetic energy of the gas. In the end, this part of the gas kinetic energy does not work externally, but is wasted in vain.

Therefore, the efficiency of the power system that obtains the recoil force from the supersonic jet and then uses the recoil force to perform work is relatively low.
