在系统地进行TИΓ—21型飞机失速/尾旋理论培训和试验飞行的基础上,结合实际飞行中的机载测试记录和体会,详细介绍了失速/尾族试飞的准备、试飞驾驶技术和失速尾旋特性。给出了MИΓ-21型飞机典型的正常尾旋和倒飞尾旋的试飞结果曲线。最后针对MИΓ-21型飞机的特点,给出了失速/尾旋试飞中特别的限制说明。供同类型飞机失速/尾旋试飞时参考。
Based on systematically carrying out the training and experimental flight of T / T-21 stutter / tail rotation theory and combining with the on-board test record and experience in actual flight, this paper introduces the preparation of stall / tail test flight, test drive technology and stall Tail spin characteristics. The results of the typical normal spin-tail and inverted spin-tail test results of the MIR-21 aircraft are given. Finally, according to the characteristics of the M-21 aircraft, special restrictions on stall / tail-flight test are given. For the same type of aircraft stall / tail rotation test reference.
