摘　　要：“锯齿法”是爬升性能试飞中常用的方法,但对试验空域内风场稳定性要求高,使用双向爬升消除风梯度影响方法效率低。文章从爬升性能数据扩展理论基础出发,分析风梯度对“锯齿法”试飞的影响,提出一种在单航向爬升中消除风梯度影响的数据处理方法,使用实际试飞数据结果进行验证,表明该方法有效。The "sawtooth method" is commonly used in climbing performance flight test, but it requires high stability of wind field in the test airspace, and the efficiency of using two-way climbing to eliminate the influence of wind gradient is low. Based on the expansion theory of climbing performance data, this paper analyzes the influence of wind gradient on "sawtooth method" flight test, and puts forward a data processing method to eliminate the influence of wind gradient in single course climbing, which is verified by the actual flight test data. The results show that the method is effective.
