AI Technical Summary

Benefits of technology

This patented device helps scientists study how an engine works better than previously it was tested without damaging its components or causing damage during testing. Its technical effect lies in that this technology allows for more precise analysis while reducing costs and risks associated with current methods such as laboratory experiments.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency or lifespan (service life) of gas turbines due to increased operating temperatures caused by higher engine speeds during operation. Current methods involve air conditioners that use expensive materials like ceramic powders and metal alloys, but these techniques have limitations because they cannot accurately predict how well their function will perform over time under different environmental factors.

Abstract

Provided in the invention is a steady-state-temperature-field-included simulation test bench of an aero-engine combustor. The simulation test bench comprises a box body, a combustion chamber simulation device, a test device, an air supply system, a ventilation system, a cooling system and a control system. The ventilation system includes an air suction type exhaust hood installed inside the lowerbox body and a wall-mounted industrial ventilation fan installed at the top of the box body. The air supply system and the cooling system are installed inside the lower box body. The control system includes a controller installed inside the lower box body and a human-machine interaction device installed on the outer side of the box body; and the controller is connected with the wall-mounted industrial ventilation fan, the human-machine interaction device, the combustion chamber simulation device, the test device, the air supply system, and the cooling system respectively. The simulation test bench can be used for simulating the actual working condition of the aero-engine combustion chamber; and the enabling performance of the thermal barrier coating material is studied preliminarily beforerun trial examination of the ground track. The steady-state-temperature-field-included simulation test bench has advantages of low cost, short cycle and low risk and the like.
