三翼面飞机低速运动下的推力矢量控制

Thrust Vector of Three Wing Aircraft at Low Speed Motion Control

针对推力矢量产生直接升力时,出现的俯仰不平衡的问题,提出了推力矢量/前鸭翼的三翼面飞机布局方案。并给出了推力矢量与气动舵面的融合方式。针对前鸭翼布局在大迎角时的旋涡破裂,导致稳定性和操纵性的突然变化以及气动力非线性产生的问题,采用非线性动态逆控制率设计方法设计快变量和慢变量的控制率。并通过‘落叶飘’非常规机动的仿真实验验证了该方案。实验结果显示,采用推力矢量三翼面布局的飞机可以获得很好的低速超机动能力。

For the direct lift of thrust vector occurs the unbalanced problem, thrust vector/front canard of three wing layout schemes has been proposed. Moreover, we also gave a thrust vector control and pneumatic control integration mode. The front canard configurations of vortex breakdown at high angles are usually leading to stability and control sudden changes and aerodynamic nonlinear problems. As to this problem, we used the nonlinear dynamic inversion of fast and slow variables control rate design methodology. Through the Leaves Floating unconventional maneuver simulation validated the program. The experimental results showed that the aircraft can get a good low-speed performance by using thrust vectoring three wing layout.
