摘　　要：The lateral stability of Velocity-173, canard-pusher type airplane, has been investigated with and without an extended vertical panel. It is well known that Velocity-173 has an excellent longitudinal stability but a relatively poor lateral stability. To improve the lateral stability, two types of composite sandwich panel have been designed and attached to the vertical tail of Velocity-173. A series of flight test has been performed to measure the effects of the extended vertical tail. Analytical methods, such as maximum likelihood estimation method and real-time parameter estimation method, have been used to extract lateral controllability/stability derivatives from flight test data. This work validates the effects of an extended panel to the lateral stability.研究了带有和不带有伸出的垂直嵌板的鸭式飞机( Velocity-1 73 )的横向稳定性。众所周知 ,鸭式飞机( Velocity-1 73 )具有良好的纵向稳定性 ,但其横向稳定性比较差。为了改善其横向稳定性 ,设计了两种复合材料夹层板 ,将其安装在垂直尾翼下面 ,并进行了一系列的飞行试验来研究安装伸出的垂直嵌板的效果。采用解析法和实时参数估计法从飞行试验数据中提取了横向可控能力/稳定性。
