摘要
运输类飞机完成空中受油类高增益闭环任务的风险性与难度均远远大于轻小类飞机,为此,对运输机软式空中受油的飞行品质试飞技术开展研究.首先,通过设计基础子集任务评估受油机基于空中受油的飞行特性,探索空中受油对接操纵策略;其次,通过研制目标跟踪系统,设计随机指令任务以评估飞行员执行高增益闭环任务时的PIO敏感性;最后,基于目标跟踪系统设计虚拟空中受油试飞任务,探索运输机空中受油试飞方法并研究相关飞行品质试飞技术.通过初步试飞验证,所提方法保障了高风险试飞任务的安全,可为大型运输机软式空中受油飞行品质试飞提供理论指导.
Abstract
The risk and difficulty of completing high-gain closed-loop tasks like aerial refueling for transport aircraft are far greater than light and small aircraft.Therefore,a research method is pro-posed for flight quality test technology based on probe and drogue aerial refueling of transport air-craft.Firstly,the flight characteristics of transport receivers arc evaluated and strategies for probe and drogue aerial refueling docking and control are explored by designing basic subset refueling tasks.Then,the PIO sensitivity is evaluated when pilots performing high-gain closed-loop tasks by designing random command tasks in specially developed target tracking system.Finally,the virtual aerial refueling test missions is designed based on the target tracking system to explore aerial refue-ling methods for transport receivers and study related flight quality test technologies.By preliminarily validation through flight tests,the method proposed can ensure the safety of high-risk flight tests and provide theoretical guidance for flight quality test in probe and drogue aerial refueling of large trans-port aircraft.
