Abstract

Abstract

In this paper, an effective wind tunnel test method is presented for evaluating the thermal protective performance of the non-catalysis material. The method is proved to be reasonable by iterating the results between CFD simulation and the wind tunnel operating parameter, taking a typical CMC(ceramic matrix composite) wedge-edge specimen for example. The operating parameters of the arc tunnel was determined by comparing the simulation results of the non-catalysis and the full-catalysis assumption. The wind tunnel test results indicate that the test on the specimen was performed as expected, which may be helpful to solve the 'under-evaluating' problem for the non-catalysis material in the non-equilibrium flow.
