摘　　要：实用升限是高空长航时无人机设计定型阶段的一项重要考核指标,本文针对高空长航时无人机实用升限试飞特点,从爬升油门控制方式选择、有利爬升速度确定、试飞操纵方法设计、试飞剖面航路规划、试飞风险评估分析5个方面对高空长航时无人机实用升限试飞方法进行设计。为将实际飞行数据向标准条件换算,确定了一套适用于高空长航时无人机实用升限试飞的数据处理方法。研究表明,本文提出的实用升限试飞技术可以满足高空长航时无人机设计定型试飞验证需求,同时还可以指导其他类型无人机的实用升限试飞工作。The service ceiling is an important evaluation indicator in the flight test stage of High Altitude Long Endurance(HALE)UAVs,this paper aimed at the characteristics of the HALE UAV service ceiling flight test,from the selection of the climb throttle control mode,the favorable climb speed determination,the control method design,the mission planning design and the risk assessment analysis,designed the service ceiling flight test method for the HALE UAV.In order to convert the actual flight data to the standard conditions,this paper determined a set of data processing method suitable for HALE UAV service ceiling flight test.The result shows that the service ceiling flight test technology proposed in this paper can satisfy the requirements of HALE UAV design and flight test verification,and can also guide the service ceiling flight test for other types of UAVs.
