Miniature turbojet engine device

Abstract

The invention discloses a miniature turbojet engine device which is used for testing the miniature turbojet engine. The miniature turbojet engine device comprises a body which is internally provided with a sliding cavity with an upward opening. A dynamic balancing instrument located on the left side of the sliding chamber is fixedly installed on the upper end surface of the body. A locating arm for clamping the miniature turbojet engine is fixedly installed on the upper end of the dynamic balancing instrument. The sliding cavity is internally provided with a sliding block capable of sliding left and right. A threaded rod is cooperatively installed in the sliding block in a threaded way. The right end of the threaded rod is rotatably installed in the right end wall of the sliding cavity, and the left end is dynamically connected with a first motor fixedly installed in the left end wall of the sliding cavity. The bottom end face of the sliding block is provided with a left-and-right extending rack. An installing frame is fixedly installed on the upper end of the sliding block. The installing frame is provided with a rotating cavity with an opening facing to the left. A thermal spraying machine is rotatably installed in the rotating cavity through a bearing.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a micro turbojet engine device. Background technique [0002] With the development of aviation technology, aircrafts put forward higher and higher requirements for the performance of the propulsion system. As a main aviation propulsion engine, the turbojet engine has high mechanical efficiency. Among the various rotating machines known at present, the general In general, turbojet engines are the most efficient. With the diversification of life style, personalization, miniaturization and light weight have become an inevitable trend in various fields, and micro turbojet engines have also become a hot topic. [0003] The working principle of the micro-turbine engine is the same as that of the traditional gas turbine engine, and it is mainly composed of a micro-compressor, a micro-turbine, and a micro-combustion chamber. First of all, when the engine starts to work, the compressor ...

Problems solved by technology

[0004] The turbine blade is an important component of the engine. After its installation is completed, it generally needs to be tested to prevent it from making a lot of noise when it rotates at high speed. The traditional test method is to use a dynamic balancer. After testing, Often, the material is sprayed on the turbine blades manually by using a thermal sprayer to achieve a balanced state, but this method has great safety hazards and is likely to cause injury to the operator
