摘要
文章介绍了变稳飞机验收试飞情况,包括试飞内容、方法、结果和结论。并分析了改变短周期频率和阻尼、系统延迟、杆力梯度、人感系统频带、配平速度以及控制模式等对飞行品质的影响。验收试飞表明,BW-1变稳飞机研制是成功的,系统工作是可靠的,它为今后我国的飞行品质研究工作开创了一个新局面。
This paper introduces the accepting flight test of BW-1 VSA (Variable Stability Aircraft) including test contents, methods, results and conclusion. And analyses the effects of longitudinal short-period frequence, damping ratio of airplane and time delege, stick force Perg, banol width of feel system,trim speed, and control mode of control system on flight quality etc.The accepting flight test shows that BW-1 VSA is successfull and variable stability control system is also relibility. It initiates a new aspect in flying qualities research in China.
