The invention belongs to the field of aircraft flight mechanics design, and relates to a method for correcting the influence of a yaw angle rate on an air minimum control speed, which comprises the following steps of: firstly, reversely deducing a slope angle of an aircraft in an actual state according to a slope angle required for balancing the yaw angle rate and a current test flight slope angle, and then calculating the influence of the yaw angle rate on the air minimum control speed through lift coefficient lateral components corresponding to different flight states of the aircraft; performing data point linear fitting on the new slope angle so as to correct a test curve, finally reversely solving the air minimum control speed in a given flight state through the corrected test curve, and finally comparing the corrected air minimum control speed with the test air minimum control speed to obtain the difference between the two to obtain the control speed. The method is clear and simple in analysis and simple to use; meanwhile, an accurate, effective and simple analysis means is provided for determining the minimum safe take-off speed of the aircraft, and theoretical support and technical guarantee are provided for safe flight in the engine failure state.

    本申请属于飞机飞行力学设计领域,为一种偏航角速率对空中最小操纵速度影响修正方法,先根据平衡偏航角速度所需要的坡度角和试飞当前坡度角反推出飞机实际状态的坡度角,而后通过飞机不同飞行状态对应的升力系数侧向分量,对新的坡度角进行数据点线性拟合,从而修正试验曲线,最后通过修正试验曲线反求出给定飞行状态下的空中最小操纵速度,最后比较修正得到的空中最小操纵速度和试验空中最小操纵速度,得到两者的差量,该方法分析明晰简单、使用简单;同时为飞机最小安全起飞速度的确定提供了准确、有效、简单的分析手段,为保障发动机失效状态安全飞行提供理论支持和技术保障。
