摘　　要：为化解单发飞机空中起动试飞的高风险,在停车迫降航线的基础上,融入空中起动试飞过程,提出了空中起动试飞航线总体设计方法、关键参数确定和修正方法、关键点确定方法以及安全裕度设置方法,形成了空中起动试飞航线建立方法。飞行试验验证表明:形成的单发飞机空中起动试飞航线建立方法合理、可行,所建立的空中起动试飞航线可操作性强、安全裕度高,能有效化解空中起动试飞存在的高风险,保障试飞安全。本研究可为单发飞机试飞安全控制和部队训练使用提供重要参考。To decrease the risk of the air-start flight test of the aircraft with single engine,a method to de⁃sign the flight course was introduced,which considered the features of air-start flight test,and the methods to calculate the key parameters plus the safety margin and to design the key flight altitudes were also intro⁃duced.The results of flight tests indicate that the methods above are feasible and reasonable,and the de⁃signed flight course is practical and promises a high safety margin which decreases the risk of the air-start flight test and guarantees the safety of air-start flight test.The research can provide the reference for securi⁃ty control of flight tests,training and employment of aircrafts with single engine.
