摘　　要：简要论述了螺旋桨气流斜吹的理论。重点分析了螺旋桨气流斜吹对飞行的影响。最后结合飞行实例，进一步分析了螺旋桨气流斜吹给飞行带来的偏差。分析结果表明，飞机在大迎角或侧滑角下飞行时，螺旋桨气流斜吹使飞机产生了附加的拉力力矩和侧力力矩，对飞机俯仰和方向平衡有明显影响，给飞行员的操纵带来不利影响。所以，在分析螺旋桨付作用对飞行的影响时，必须考虑螺旋桨气流斜吹的作用。This paper discusses simply the theory of propeller air current tilted blowwing(PACTB) from physics concept,and analyses mainly the effect of PACTB in flight .And it also analyses further the deviation taken by PACTB in flight by combining the flight examples at last.The analysing results show that additive pullforce and sideforce moments are caused by aircraft PACTB in high angle of attack or high sideslip angle ,and these moments will cause the obvious effect for aircraft pitch and direction balance and bring unfavourable influence for pilot,controlling.So the effect of PACTB must be considered when we analysis the deleterious effect of propeller to flight.
