Micro turbojet engine test device and using method thereof

Abstract

The invention discloses a micro turbojet engine test device used to test a micro turbojet engine. The device includes a body which is internally provided with a sliding chamber opened upwards. A dynamic balancer on the left side of the sliding chamber is fixedly installed on the upper end face of the body. Positioning arms used for clamping a micro turbojet engine are fixedly installed on the upper end of the dynamic balancer. A sliding block which can slide from side to side is installed in the sliding chamber. A threaded rod is installed in a threaded fit manner in the sliding block. The right end of the threaded rod is rotationally installed in the right end wall of the sliding chamber, and the left end is in power connection with a first motor in the left end wall of the sliding chamber. A rack extending to the left and right is arranged in the bottom end face of the sliding block. An installation rack is fixedly installed on the upper end of the sliding block. The installation rack is internally provided with a rotating chamber opened leftwards. A thermal spraying machine is rotationally installed in the rotating chamber through a bearing.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a test device for a micro turbojet engine and a method for using the same. 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...

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
