摘　　要：尾旋是在超临界迎角上发生的气动旋转现象,是飞机最复杂和最危险的飞行状态之一,直接危及飞行员和飞机的安全。为了更好地研究飞机尾旋运动的机理和动力学特性,本文从原理上分析了空气动力、力矩和惯性交感等因素对尾旋特性的影响,为分析飞机尾旋进入和改出机理提供了理论参考。The spin, one of the most complicated and dangerous flight states of aircraft, is an aerodynamic rotation phenomenon occurred at super-critical angle-of-attack, and directly threatens the safety of pilot and aircraft. In order to study principle and dynamic characteristics of aircraft spin motion better, the paper analyzes the effect of factors such as aerodynamic force, moment and inertia interaction on spin characteristic on the principle, and provides theoretical reference for analyzing principle of aircraft entering into and recovering from spin.
