According to the aerodynamic heating conditions of large scale model with high enthalpy,low heat flux for a long time, the Φ1 m Arc heated wind tunnel was constructed with the quartz lamp radiation heating technology inducted, and test was done on the large scale fiat model of 400 mm × 400 mm. The results show that this combined heating method can be effectively used for the thermal protection and insulation performance test, together with the ablation-thermal-structure test.
