For thermal protection panel of quasi-waverider

the loose coupling algorithm was applied to drive the iteration of the aeroheating and heat transfer analysis. Then

the coupling characteristics of aeroheating-temperature field were studied. The results show that

before radiative equilibrium

the errors of cold wall and radiative equilibrium aeroheating are +55.1% and -15.4% over actual aeroheating respectively

so coupling analysis for aeroheating-temperature field was required. As the local adiabatic wall temperature is not changed with time

the surface heat-transfer coefficient is a key parameter for coupling effect. Only two aeroheating calculations are needed during calculation of coupling aeroheating-temperature field with average heat convection coefficient

and the error of predicted wall temperature is less than 2.5%

thus highly improving the analysis efficiency of coupled aeroheating-temperature field.
