Abstract

The invention belongs to the field of gas turbine engines of aviation, ships, ground gas turbines and the like, and particularly relates to a gas turbine engine component thermal state performance test protection device. The device comprises a first mounting edge, a distance fixing rod, an elastic channel and a second mounting edge. According to the invention, a fixed-distance compensation mode isadopted to replace an existing gas turbine engine component thermal state performance test design structure, so that it is guaranteed that gas turbine engine components are not damaged, and the testcost is reduced. In addition, by the adoption of the technical scheme, the gas turbine engine test component directly uses an engine installation part, so that the number of processed test pieces is reduced, the test cost is reduced, the real working state of the test component is simulated, and the test data accuracy is improved.

Description

technical field [0001] The invention belongs to the field of gas turbine engines such as aviation, ships, and ground gas turbines, and in particular relates to a thermal performance test protection device for gas turbine engine components. Background technique [0002] The main components of gas turbine engines include compressors, combustion chambers, turbines, nozzles and other components. The turbofan gas turbines also include afterburning. It is complex and the working environment is very harsh. The combustion outlet temperature of the new generation of gas turbines is generally not less than 2000K, and the compressor outlet pressure is not less than 3.0MPa. Existing theories, experiences and calculation methods cannot accurately predict the working status and performance of gas turbine engine components At present and for a long period of time in the future, a large number of experimental studies and verifications are still needed to obtain the real performance of engin...

AI Technical Summary

Problems solved by technology

[0003] Taking the combustion chamber as an example, at present, the performance tests of some combustion chamber components at home and abroad use special thickened combustion chamber casings to absorb and transmit equipment loads. There are differences between the combustion chamber casings and the actual installed combustion chamber casings. The accuracy of the results is adversely affected, and the combustion chamber casing cannot be used to assemble the engine, but can only be used for component tests, thereby increasing test costs

Part of the test uses the main combustion chamber components for installation, but only relies on the free sliding design of the test equipment (bench) to transmit and absorb the equipment load. Under the influence of equipment aging, sliding friction and aerodynamic interception, the main combustion chamber components may bear certain Equipment load, the risk of the test is relatively high, and may affect the life of the main combustion chamber components, and have an adverse effect on the reliability assessment of the components. The same problem exists in the thermal performance tests of other gas turbine engine components
