Abstract:
The temperature variation of gas-generator exhausting shell and turbine's inlet-outlet housing are analyzed during No. 001~003 hot test of liquid rocket engine (LRE). With unsteady heat transfer methods, the temperature variation of turbine housing caused by the gas-generator working at different flow rate and efficient in the 003 time hot test were simulated. The simulation result shows that the overheating of turbine housing is because of too much high efficiency of gas-generator.
