Embodiment Construction

[0024] like figure 1 As shown, the rotary combination valve includes a valve body 1 and a valve core 2 arranged in the valve body 1. The valve core 2 is a disc-shaped valve core, and the surface of the disc-shaped valve core is provided with more than one ventilation hole. The air hole group is composed of air through holes 3 and gas through holes 4, and the upper surface and lower surface of the valve body 1 are respectively provided with upper air ducts 5 corresponding to the air through holes 3 and the lower air conduit 6, the upper surface and the lower surface of the valve body 1 are respectively provided with an upper gas conduit 7 and a lower gas conduit 8 corresponding to the gas through hole 4, the rotating valve core 2, the air through hole 3. The upper air conduit 5 and the lower air conduit 6 can be turned on and off repeatedly, and the gas through hole 4 can be turned on and off repeatedly on the upper gas conduit 7 and the lower gas conduit 8. The upper air duct...

Abstract

The invention discloses a rotary combination valve and pulse detonation-type engine. The rotary combination valve comprises a valve body and a valve core in the valve body; the valve core is in a disc shape, the surface of the disc-shaped valve core is provided with more than one ventilation hole group; the ventilation hole group is composed of an air hole and a gas hole; when the valve core rotates, the air hole can repeatedly turn on and off on an upper air duct and a lower air duct, and the gas hole can repeatedly turn on and off an upper gas conduit and a lower gas conduit. The valN2}>valve with the above structure greatly improves the working frequency of the detonation engine; the upper air duct, the lower air duct, the upper gas conduit and the lower gas conduit of the valve form a group, and two groups are arranged on the valve body and can work for two engines at the same time. The invention can replace an electromagnetic valve in the detonation engine, thus to simplify the control of air and gas.

Description

technical field [0001] The invention relates to a valve and a pulse detonation engine. Background technique [0002] Pulse detonation engine (PDE for short) is a power device with a new concept that uses high-temperature and high-pressure gas generated by intermittent or pulse detonation waves to generate thrust. PDE has the advantages of high cycle thermal efficiency, low fuel consumption rate, simple structure, light weight, high thrust-to-weight ratio, large specific impulse, and adjustable thrust, and has become a major research hotspot in the field of engines today. Pulse detonation combustion is a kind of unsteady combustion. The parameters such as pressure, temperature, combustion products and component concentrations in the combustion chamber change at high frequency. It is very important to quickly and accurately obtain the changing rules of parameters in the combustion chamber. important. [0003] In the existing pulse detonation engine, the output control of air...
