摘要
在小扰动假设的前提下,用正则模态法对计及弹性自由度的JJ-7飞机的纵向稳定性及操纵性进行了计算和分析,并与不计及弹性自由度飞机的动态特性进行了比较,由此讨论了弹性变形对这种类型飞机动态特性的影响。
On the premise of assumption of small disturbance, the longitudinal stability and cortrol characteristics of JJ-7 aircraft, the elastic degrees of freedom of which are took into account, are computed and analysised, and compared which the JJ-7 aircraft, the elastic degrees of freedom of which are not took into account. Based on this, authors discuss the influence of elastic deformation on dynamic characteristics for this type of aircraft.
