For the wing with some deflection angle,the windward angle and the deflection an-gle will directly influence the position where heat flux is the highest on the arc surface of the lead-ing edge.In this paper,based on the triangle theory of the ball surface and the calculation formu-la of heat flux about the cylinder with some sweepback angle,the function equation about the windward angle and the deflection angle and the deviation angle (Deviate the center line on the lending)was derived.When the any two angles were determined among the three angles dis-cussed above,another angle was also obtained according to the function,which was the place where the heat flux was the highest.Those results are basically the same with the experimental results and the empirical results,which almost satisfies engineering requirements.In the end, the variation for heat flux on the leading edge were analyzed when the windward angle and the de-flection angle.
