The invention belongs to the field of test flight, and particularly relates to a test flight method for a stall speed of a turboprop aircraft, which is suitable for a stall speed flight test of the turboprop aircraft. The test condition is determined according to the sequence of the flap configuration, the aircraft weight and the engine state, the test flight risk of the stall speed of the propeller-driven aircraft is comprehensively recognized according to the principle of gradual approaching in the engine state changing process, the reasonable test sequence and risk degradation measures are formulated, the test flight risk can be effectively reduced, and the test efficiency is improved. And powerful support can be provided for qualified stall speed certification test flight and identification test flight of the propeller-driven aircraft.

    本发明属于试飞领域,具体涉及一种涡桨飞机失速速度的试飞方法,适用于螺旋桨飞机失速速度飞行试验。按照襟翼构型、飞机重量、发动机状态的顺序确定试验工况,改变发动机状态过程中按照循序渐进、逐步逼近的原则,较为全面的识别出了螺旋桨飞机失速速度的试飞风险,制定了合理的试验顺序以及风险降解措施能够有效的降低试飞风险,能够为螺旋桨飞机失速速度合格审定试飞和鉴定试飞提供有力的支撑。
