摘　　要：对于偏转翼,其迎风角和偏转角直接影响到前缘弧面上热流最高点的分布位置。运用球面三角学原理并基于后掠圆柱热流计算公式推导偏转翼的迎风角、偏转角和离心角(前缘弧面上偏离前缘中心线的角)之间的关系。在确定迎风角和偏转角的条件下,应用该式可以直接确定前缘弧面上最大热流的分布位置,该结果与实验及工程计算结果基本一致,可以基本满足工程使用要求。最后分析前缘上最大热流位置随迎风角及偏转角的变化规律。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.
