Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Please refer to the accompanying drawings, in the figure, the front nut 1 is mounted on the front end of the shaft 3, and is used to compress the centrifugal compressor rotor 2, the front bearing 5, the sleeve 19, and the oil throwing pan 8 on the shaft 3. Adopt simple and simple centrifugal pump to pump air on the front nut 1, to cool DC motor 18 (as attached Figure 6 As shown), two symmetrical oblique holes are centrifugal pumps, which naturally saves a more complicated cooling system. The centrifugal compressor rotor 2 is installed on the shaft 3 and rotates with the shaft 3 at a high speed to pressurize the air. The front casing 4 is installed on the compressor support ring 7, which is not only the engine air inlet, but also the compressor pan cover. One front bearing 5 and one rear bearing 21, the front bearing 5 is installed between the shaft 3 and the ...

Abstract

A miniature turboject engine with 10-30 kg of propulsive force is composed of air inlet channel, compressor, combustion chamber and exhaust system. The front and back nuts, rotor of centrifugal compressor, oil thrower and turbo rotor are installed on the shaft of engine. It has also the flame barrel, tail jet nozzle, shaft couple and DC motor. Its advantages are simple structure, small size and light weight.

Description

technical field [0001] The present invention relates to an engine, more particularly to a micro turbojet engine. Background technique [0002] At the end of the 1950s, Williams International Company of the United States saw the application prospects of small turbine engines in future wars and aerospace, and designed and produced 50 kg thrust class WR2 and WR24 series small turbojet engines. Since the late 1990s, with the maturity and exquisiteness of large turbine engine technology, the United States, Germany, Japan, and the United Kingdom have produced micro-turbine engine products with a thrust of tens of kilograms or less. Among them, at least 5 companies in the United States are engaged in different levels of production. [0003] Chinese scholars saw this development trend in the late 1990s. In particular, microturbine products will be widely used in different fields of military and civilian use, and will play an important role in future wars. F...
