摘　　要：根据在确定 Ｙ７２００ Ａ 飞机失速速度中所遇到的困难， 提出了确定 Ｙ７２００ Ａ 飞机失速速度的新方法。在对该机双发空中慢车功率状态推力为负进行了验证的基础上， 对所有构形的失速速度试飞均以双发空中慢车状态来完成。最后， 给出了失速速度试飞结果。结果表明， 该方法在试飞中是切实可行的， 可用于同类型飞机的试飞验证。It is difficult to determine the stall speed in type certification flight test when the thrust at flight idle is negative. This paper presents a new method of determining the stall speed in Y7 200A aircraft type certification flight test with negative thrust at flight idle. The stall speed flight test is finished in all configurations with both engines at flight idle condition, after negative thrust with twin engine at flight idle has been validated. The stall speed flight test results have been given at last and show that this method is practicable and applicable to similar aircraft.
