Abstract

The embodiment of the invention discloses a small turbojet engine test bench. The small turbojet engine test bench includes an engine test bench and a data acquisition and control system; the engine test bench is used for installation and testing of various types of small turbojet engines; and the data acquisition and control system includes a hardware part and a software part for processing and analyzing data after engine testing. The small turbojet engine test bench is applicable to a universal test system of a small turbojet engine mobile test bench; that is, the invention draws on the advanced experiences in testing, control, data processing and the like of a computer-aided test system, and builds a small turbine shaft engine universal test system with perfect performance and strong universality, so as to satisfy the general test requirements of a test bench for a small turbojet engine; and the test system can complete the complex work such as program loading, parameter testing, data processing, result analysis and the like during a engine test process; therefore, the work intensity of the operator is reduced, the engine test and test cycle is shortened, and the cost of enginetest is reduced.

Description

technical field [0001] The embodiment of the invention relates to the technical field of aero-engine testing and testing, in particular to a small turbojet engine test bed. Background technique [0002] High-performance small turbojet engine is one of the key technologies for the development of high-altitude and high-speed UAVs and cruise missiles. The stability and reliability of its performance are directly related to whether the equipment can work normally. The small turbojet engine is not proportional to the large engine, it has its own unique performance, such as low pressure ratio, high speed, high temperature gradient, large tip clearance loss, etc. The test bench test accuracy cannot meet the test requirements of small engines. [0003] The small turbojet engine test bench is a non-standard product. There are few relevant domestic standard materials, and there is no design idea for reference. The design scheme can only be explored based on relevant test theory and e...
