摘要
最小离地速度(Vmu)试飞是民用飞机最大性能起飞的试验机动,是在地面效应影响条件下飞机的低速大迎角试飞科目,试验难度大、风险高。针对受几何结构限制的民用运输类飞机Vmu的试飞设计和风险控制技术,研究不同飞机Vmu试飞状态矩阵选择方法,总结Vmu试飞的风险控制技术,对深化国内Vmu试飞技术研究并应用于未来客机型号具有非常重要的作用。
Minimum unstick speed （Vmu） testing to demonstrate the lowest Vmu speed is a maximum performance flight test maneuver, and liftoff may occur whenit is very close to the angle-of-attack for maximum lift coefficient. Also, transiting through ground effect at Vmo may result in high hazards and difficulty. In this paper, minimum unstick speed test design and hazards control measures was studied, and Vmu flight testing matrix selection was also given. This paper would play a very important role in Vmuflight testing study.
