从平尾失速理论研究出发,探讨了可能产生平尾失速的飞行状态,总结了可用于运输类飞机平尾失速敏感性研究的飞行试验技术,研究了平尾失速和机翼失速的相互区别,帮助飞行员在遇到机翼失速或平尾失速时进行必要的清晰判断,并采取适当的改出方法,从而保证飞机飞行安全。研究结果可为未来大型运输类飞机平尾失速敏感性试飞提供很好的技术支持。 Based on the theory of horizontal tail stall, this paper discusses the possible flight states of horizontal tail stalls, summarizes the flight test techniques that can be used to study the sensitivity of horizontal tail stalls of transport aircraft, and studies the mutual differences between horizontal tail stalls and wing stalls, To the wing when the stall or flat-tail stall to make the necessary clear judgments, and take appropriate ways to change, so as to ensure the safety of the aircraft flight. The results of this study can provide good technical support for the flight-tail stall sensitivity test of large transport aircraft in the future.
