摘　　要：最小离地速度是民用运输类飞机制定起飞特征速度的关键。最小离地速度试飞是民用运输类飞机最大性能起飞的试验机动,是在地面效应影响下的飞机低速大迎角试飞科目,试验难度大、风险高,对试飞技术、试飞组织和试飞驾驶技术要求很高。目前国内仅有新支线飞机按照民用航空规章进行了相关试验。研究了民用运输类飞机最小离地速度试飞的类型和理论,对运输类飞机最小离地速度试飞中的关键技术和风险控制方法进行了深入研究,可供所有类型运输类飞机最小离地速度试飞借鉴使用。The minimum unstick speed is the key to determine the take-off characteristic speeds of civil transport airplanes.The minimum unstick speed flight test is the test maneuver of the maximum performance take-off for civil transport airplanes.It is a flight test subject of low speed and large angle of attack under the influence of ground effect.The test is difficult and high risk.It has high requirements for flight test technology,flight test organization and flight test driving technology.At present,only the new regional airplane in China is tested in accordance with the rules of civil aviation.The type and theory of the minimum unstick speed flight test for civil transport airplanes were studied. The key technology and risk control methods of the minimum unstick speed flight test of the transport airplanes were studied,which can be used for reference for the minimum unstick speed test of all types of transport airplanes.
