摘要
重装空投飞行试验过程中,货物运动会导致飞机姿态变化过大,影响飞行安全;为了保证重装空投飞行试验安全,建立了空投过程数学模型,预测空投过程飞机响应、使用“预测→验证→比较→预测”的方法指导飞行试验循序渐进实施;在空投试飞前,分析空投货物时飞机响应特点,确定载机平台飞行品质试飞内容,评价空投构型飞行品质,作为空投飞行试验的前提;对于空投任务飞行试验设计从试飞状态选择、试飞员操纵方法设计两方面开展研究,以飞机姿态控制为目标,确定重力空投、牵引空投过程飞机飞行状态、给出飞行员操纵建议,设计了空投过程评价要素表,形成面向空投任务的飞行试验设计及飞行品质评价技术;提出的基于模型的试验设计方法及飞行品质评价方法可以有效保障空投任务执行,并全面充分地评价空投任务下的飞行品质。
In the process of heavy load airdrop flight test,the movement of cargo will lead to excessive changes of aircraft attitude,which affects flight safety.In order to ensure the safety of heavy load airdrop flight test,a mathematical model of the airdrop system is built to predict aircraft response during airdrop process,the“prediction validation comparison prediction”method is used to gradually guide flight tests,analyze the aircraft’s response characteristics with cargo airdropping before airdrop test flights,determine the flight quality and test flight of the carrier platform,and evaluate the quality of airdrop flight as a prerequisite for airdrop flight testing.The research on airdrop flight design is conducted from two aspects:the section of test flight states and the control methods of test pilots,The aircraft attitude control is taken as the target to determine the test flight status of the gravity airdrop and extraction airdrop,give the pilot manipulation suggestions,design the table of airdrop process evaluation elements,and achieve the flight quality flight test design and evaluation technology for the airdrop mission.The proposed design and flight quality evaluation method based the model provides a technical support for the execution of airdrop missions,and fully evaluate the flight quality of airdrop missions.
