飞行力学和飞行控制试飞技术

为了适应高增益，全权限数字电传操纵系统飞行试验的需要，利用已研制成功的多台地面飞行模拟器和ＢＷ－１纵向，ＩＦＳＴＡ三自由度空中飞行模拟试验机，模型自由飞研究以及具有现代先进水平的机载数据采集记录和地面实时监控系统等设备和技术手段，进行了电传飞机的飞行品质和飞控稳定性等问题的研究，包括试飞输入设计，电传飞机飞行品质，电传飞控系统稳定裕度等。最后，提出了对下一代飞机飞行力学和飞行控制方面需要研究的试飞

Flight Test Techniques on Flight Dynamics and Flight Control

In order to adapt flight test of highly augmented digital fly by wire control system,we have developed several ground based flight simulators,BW 1 longitudinal variable stability aircraft and IFSTA three degree of freedom variable stability aircraft.Moreover, the on board data acquisition system and ground real time monitoring and data processing systems were built for assuring flight test safety and effectiveness.At the same time, the model free flight has been investigated widely to carry out research of high AOA of static unstable aircraft with fly by wire control system. By using these devices and means, we have investigated on flying quality and flight control stability of fly by wire aircraft,including flight test control input design, flying qualities and stability margin flight test,etc.Finally,the research work in the future on flight test techniques of flight dynamics and flight control for future new aircraft is proposed.
