In order to simulate the complex aerodynamic heating environment in local interference zone of an aircraft, this paper establishes a sophisticated experimental simulation technology for based on arc flat plate free jet test technology. A water-cooled device is installed locally model, leaving certain gap between and therefore strip-shaped flow thermal established. Experimental research has found that diagonal shock wave formed near block, heat flux inside relatively large, similar results obtained from numerical simulations. The larger angle block within range, greater ratio, which can situation aircraft with large gradient distribution more realistic way.
