Combustion-explosion type air injection rotor engine

Abstract

The detonation type jet rotor engine includes one rotor on one rotor shaft and with one combustion chamber, one stator fitting the rotor, one igniter communicated to the combustion chamber and one fuel gas mixing nozzle. It has certain angle between the fuel gas jet of the combustion chamber and the rotor diameter through the jet, a jet passage communicated to the engine exhaust port in the stator, and a fuel gas jet sealed by the fitting surface between the stator and the rotor and communicated to the jet passage. When the mixed fuel gas is jetted to the combustion chamber and the detonated high temperature and high pressure gas is jetted to the jet passage, the combustion chamber is one sealed cavity without fuel leakage and with high detonated gas temperature. The present invention has high pressure and high speed of the jetted gas, great output powder, compact structure, less noise, smooth rotation, high combustion efficiency and other advantages.

Description

technical field [0001] The invention belongs to an internal combustion engine, in particular to an explosion-type jet rotary engine driven by jet reverse thrust. Background technique [0002] Cylinder-piston engine is the longest and most widely used engine, but compared with jet rotary engine, it has structural shortcomings such as low thermal efficiency, complex structure and many parts, bulky body, large vibration and noise. In the jet rotary engine technology disclosed in Chinese Patent No. 93111980.4 "Jet Rotary Engine" and Chinese Patent No. 03124571.4 "Recoil Rotary Engine", the inner cavity of the rotor or disc is the combustion chamber, and the fuel burns and expands in the combustion chamber, and the high temperature The high-pressure gas is jetted out at high speed from the airflow channel or the outlet called the nozzle, which generates a strong reverse thrust to push the rotor (disc) to rotate at a high speed in the direction opposite to the jet, and the power i...

AI Technical Summary

Problems solved by technology

The rotary engine of disclosed technology overcomes the shortcoming of cylinder piston engine to a great extent, but in the whole working process, their combustion chamber communicates with the outside world through air flow passage (nozzle), this aspect makes a part of the fuel that does not burn It is directly discharged from the airflow channel (nozzle) and is wasted. On the other hand, the temperature of the fuel combustion in the combustion chamber is low, and the gas pressure after ignition is low, so that the efficiency of the engine is low, and the output power of the rotor (disc) shaft is high.
