The Testing Simulation Technology Investigation on the Thermal Environment of Engine Combustor Wall Material

AbstractThe focus of this paper is on the thermal environment simulation of engine combustor inner wall in the ground experiment facility. The inner flow and outer flow thermal environment has usually taken place in the inner surface of engine combustor and the outer surface of hypersonic vehicle, respectively. These two kinds of thermal environments have been compared by using the supersonic rectangle Turbulent Flow Duct (TFD) and arc heater.The arc-heated double-models supersonic rectangle TFD experimental technology can commendably simulate the inner flow thermal environment of the engine combustor. The passive, semi-passive and active thermal protection structures of combustor can be tested by this technology for the thousands-scale exposure periods
