Problems solved by technology

The disadvantage of the pulse detonation engine is that it has single purpose and high noise. At present, it can only be used in the flight system in the form of jet propulsion. There is no new type that can convert its propulsion energy into output energy in the form of output torque from the output shaft. shaft engine emerges

Embodiment 1

[0033] Embodiment 1: only have the pulse detonation rotor shaft motor of a pulse detonation motor: (as attached figure 1 , attached Figure 1.2 ) is mainly composed of a pulse detonation engine 1 with an intake valve 9 and a three-stage impeller rotor 4 driving an output shaft 5, etc., and its working process is that the air in the pulse detonation engine 1 is mixed with the fuel injected by the fuel nozzle 10 , the igniter 11 ignites the pulse detonation engine 1 to work, and the propelling gas 2 produced completely enters the casing 6 connected to it through the propelling gas ejection port 12. There is a water nozzle 13 in the propelling gas ejection port 12, and the ejected The atomized water can absorb the heat energy in the high-temperature and high-pressure propellant gas 2 and turn it into water vapor to increase the thrust of the propellant gas 2. The rest of the water can continue to evaporate in the shell 6 to cool down the engine. 6. Push the blade 3 on the impel...

Embodiment 2

[0034] Embodiment 2: a kind of pulse detonation rotor shaft engine that uses hydrogen and oxygen to work completely: (as attached figure 1 ) The original structure in the specific embodiment 1 remains unchanged, but on its basis, the upstream of the intake valve 9 of the pulse detonation engine 1 is airtightly connected with the hydrogen supply pipe, the gas supply regulation system, and the hydrogen cylinder (not shown) , the upstream of nozzle 10 is airtightly connected (not shown) with oxygen supply pipe and gas supply regulation system, oxygen bottle, and makes the hydrogen / oxygen=2 / 1 (mol ratio) that enters pulse detonation engine 1 by gas supply regulation system , and the rest of the working process is identical with that in specific embodiment 1. Make pulse detonation engine 1 become the pulse detonation rocket engine (PDRE) that uses hydrogen, oxygen fuel by air-breathing pulse detonation engine (PDE) like this, make pulse detonation rotorshaft engine of the present ...

Embodiment 3

[0035] Embodiment 3: (as attached figure 2 ) The impeller driven by multiple pulse detonation engines, the turbo composite rotor type pulse detonation rotor shaft engine: its working process is the propelling gas 2 produced by 12 pulse detonation engines with intake valves 1 working, after water spraying After boosting, the propellant gas enters the same engine casing 6 connected to it through each propellant gas ejection port 12, and jointly tangentially pushes the impeller blades 3 to rotate the impeller rotor 4 and drive the output shaft 5 to rotate. At this time, the direction of the propellant gas 2 has been After being changed by the impeller blades 3, the turbine blades 3 of the downstream turbine rotor 4 are pushed again to make the turbine rotor 4 rotate. There are air guide stator blades 19 fixed on the inner wall of the casing 6 in front of the turbine blades 3 of each stage of the turbine rotor 4. In the figure, there are 1-stage impeller rotor and 3-stage turbine...

Abstract

The present invention relates to a pulse detonation rotor shaft engine. In the technical proposal, the pulse detonation rotor shaft engine mainly consists of a pulse detonation engine, a rotor and an output shaft; propulsive gas with the high temperature and high pressure expansion of pulse which is ejected when the pulse detonation engine works is used as a power source to push the rotor to rotate; the rotor drives the output shaft to rotate; a pulse detonation rotor shaft engine uses the output shaft to output most energy produced by the pulse detonation engine by outputting torsion continuously; the output shaft drives various kinds of loads to work. The pulse detonation rotor shaft engine has the beneficial effects as follows: firstly, the pulse detonation rotor shaft engine can be used as a shaft engine to be widely applied in various kinds of dynamic systems, such as ship, submarine, tank, tractor, automobile, train, and the like and has wide purposes; secondly, the pulse detonation rotor shaft engine overcomes the disadvantage of the large noise of the prior pulse detonation engine; thirdly, compared with a piston type engine, the pulse detonation rotor shaft engine has theobvious advantages of simple structure, low cost, high reliability, long service life, light weight, less fraction resistance loss, etc.

Description

1. Technical field: [0001] The invention relates to an engine, in particular to a new-concept pulse detonation rotor shaft engine. 2. Background technology: [0002] At present, the engines that have been widely used to generate high-temperature and high-pressure gas after fuel combustion as the power source, and output most of the power through the output shaft in the form of output torque mainly include reciprocating piston internal combustion engines and gas turbines. Reciprocating piston internal combustion engine: Its normal operation must rely on the precision machining sealing fit between the piston and the cylinder liner. The friction loss between the piston and the cylinder liner is large, and it has extremely high requirements for lubrication and cooling. Once the sealing performance is worn If it is lowered, the pollution will increase, the output power will decrease, and the service life will be short; once the cooling is not good, there will be lockup; the trans...
