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。本文的工作验证了安装垂直嵌板对横向稳定性的效果
The lateral stability of a Ducklane with and without an extended vertical panel (Velocity-1 73) was investigated. It is well known that the Velocity-1 73 has good longitudinal stability, but its transverse stability is poor. In order to improve their lateral stability, two composite sandwich panels were designed, installed under the vertical tail, and a series of flight tests were conducted to investigate the effect of installing the extended vertical panel. Lateral controllability / stability was extracted from flight test data using analytical methods and real-time parameter estimation. The work in this paper verifies the effect of installing vertical panels on the lateral stability
