摘要
分析了飞机在尾旋中产生侧滑和坡度的根本原因，论述了侧滑和坡度在尾旋中变化的规律、影响侧滑和坡度的因素，以及侧滑和坡度变化对尾旋动态的影响。同时就尾旋中偏滚对尾旋侧滑的影响、绕铅垂轴旋转对坡度的影响等进行了讨论分析。最后通过分析ＪＪ６飞机和ＪＪ５飞机尾旋的测试曲线，进一步说明了ωｘ和ωｙ对坡度的影响，可为飞行员掌握尾旋特性、提高飞行技术和保证飞行安全提供参考。
This paper analyses the main reasons both in physics and mathematics of the appearance of sideslip and angle of bank of aircrafts in spin,and describles the rules of the changes of sideslip and angle of bank in spin, the elements affecting sideslip and angle of bank,and the effects on dynamic state of spin caused by changes of sideslip and angle of bank. Meanwhile, it also discusses the influence of roll yaw on sideslip in spin, and of moving round plumb line on angle of bank. In the last, it illustrates the effects of ω x,ω y on angle of bank by analysing the test curve of JJ5 aircraft and JJ6 aircraft. This paper is important for pilot to master the specific properties of spin and enhance their skill of flight, and it is also important to ensure the safety of flight.
