The invention provides a fly-by-wire civil aircraft stall test flight method based on a high angle-of-attack protection function. The fly-by-wire civil aircraft stall test flight method comprises the steps that 1, preparation work before test flight is completed; step 2, performing stall characteristic test flight verification under an auxiliary control law, and preliminarily confirming a protection angle of attack and a maximum angle of attack of high angle of attack protection of the fly-by-wire civil aircraft; step 3, performing stall characteristic test flight verification under a normal control law, and determining an attack angle working range of the high attack angle protection by loading the protection attack angle and the maximum attack angle of the high attack angle protection determined in the step 2; step 4, performing stall characteristic test flight verification on the fly-by-wire civil aircraft in each scene; and step 5, performing stall characteristic flight test verification in an attack angle overshoot state. According to the technical scheme provided by the embodiment of the invention, through reasonable task planning, test flight action criterion and data processing, the stall envelope of the aircraft can be safely and effectively tested under the high vibration characteristic.

    本发明提出一种基于高迎角保护功能的电传民用飞机失速试飞方法,包括:步骤1,完成试飞前准备工作;步骤2,在辅助控制律下进行失速特性试飞验证,初步确认出电传民用飞机的高迎角保护的保护迎角和最大迎角;步骤3,在正常控制律下进行失速特性试飞验证,通过加载步骤2中确定的高迎角保护的保护迎角和最大迎角,确定出高迎角保护的迎角工作范围;步骤4,在各个场景下对电传民用飞机进行失速特性试飞验证;步骤5,在迎角超调状态下进行失速特性试飞验证。本发明实施例的技术方案通过合理的任务规划、试飞动作判据、数据处理,从而保证在高振动特性下,能安全且有效地试验出飞机的失速包线。
