Micro turbojet engine

Abstract

The invention discloses a micro turbojet engine. The micro turbojet engine comprises a compressor box, a cowling, a compressor impeller, a diffuser, a combustion chamber, a turbine, a housing and a shaft. The cowling is disposed on the end of the housing, and the compressor box is disposed on the central section of the cowling. The shaft is disposed rotationally on the axis position of the housing, the compressor impeller is disposed on the end closed to the compressor box of the shaft, and the turbine is disposed on the other end. The diffuser is disposed between the compressor impeller and the turbine and closed to the compressor impeller, and a motor rotor and a motor stator are disposed between the compressor impeller and the diffuser. The micro turbojet engine changes the pneumatic starting into direct current motor starting, and the permanent magnet direct current motor is disposed between the compressor impeller and the diffuser, so that the motor is used as a starting motor and a generator. The micro turbojet engine is convenient to start, and the started motor changes to be the generator, so that the micro turbojet engine can be used as two ways.

Description

technical field [0001] The invention relates to the technical field of turbojet engines, in particular to a miniature turbojet engine. Background technique [0002] A micro turbojet engine refers to a jet turbine engine with a thrust of less than 100 kg. The jet turbine engine uses air as the medium. After compression, it mixes with fuel in the combustion chamber and burns to generate high-temperature and high-pressure gas. The chemical energy is converted into mechanical energy through the turbine. powerplant. According to the utilization of its energy, it can be divided into turbojet engine, turbofan engine, turboprop engine and turboshaft engine. Micro-turbojet engines are widely used in the army field, as follows: 1. As the power of small and medium-sized aircraft, such as drones, target aircraft, targets, missiles, decoy bombs, paragliders, etc. 2. As auxiliary power on ships, tanks, and large aircraft, such as air-conditioning power, partial power of ships, power of ...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the connection between the electronic control part and the fuel supply system is relatively complicated. Some components such as the oil pump and the control system module (ECU) are heavy and bulky, which increases the production cost and reduces the performance of the micro turbojet engine. and not easy to install
