Problems solved by technology

However, rotary valve detonation engines generally adopt the form of multi-tube installation. The multi-tube structure makes it difficult to coordinate valve control, and there are problems such as coordination and control of air intake and ignition between multiple tubes, and each detonation tube All need to be equipp

Abstract

The invention relates to the technical field of pulse detonation engines, in particular to a rotating-tube-type multi-tube pulse detonation engine. The rotating-tube-type multi-tube pulse detonation engine comprises a driving motor, a detonation engine spindle coaxially and fixedly connected with an output shaft of the driving motor, and at least two detonation tubes, and the axes of the detonation tubes are arranged to be parallel to the axis of the detonation engine spindle; the rotating-tube-type multi-tube pulse detonation engine further comprises a first detonation tube connecting disc used for being connected with the detonation tubes, first round holes matched with the detonation tubes in diameter are perpendicularly formed in the position, directly facing the axes of the detonationtubes, of the first detonation tube connecting disc in a penetrating mode, and the detonation tubes are fixedly mounted in the first round holes; and the detonation engine spindle drives the detonation tubes to rotate around the axis of the detonation engine spindle through a multi-orifice valve, the end, directly facing the driving motor, of the multi-orifice valve is provided with an explosivemixed gas piping assembly, an air piping assembly and an ignition cable, and the side, back to the driving motor, of the multi-orifice valve is fixedly connected with the ends of the detonation tubes.

Description

technical field [0001] The invention relates to the technical field of pulse detonation engines, in particular to a rotary tube type multi-tube pulse detonation engine. Background technique [0002] Pulse detonation engine is a new concept engine that uses detonation combustion wave to generate thrust. Since the propagation speed of the detonation wave is extremely fast, up to several thousand meters per second, the combustion products have no time to expand during the combustion process, and the detonation process is very close to the constant volume combustion process, so theoretically, its cycle thermal efficiency is significantly higher than that of the constant pressure combustion process. Conventional aero-engines based on the combustion process. In addition, because the detonation process also has a strong supercharging capacity, the detonation engine can eliminate rotating components such as compressors and turbines, so it also has the advantages of simple structure...
