摘要
鸭式布局指空气舵位于飞行器前部,与正常式布局相比,鸭式布局空气舵的控制效率高、响应快、升阻比大,可以实现飞行器较小外包络尺寸约束下的强机动、高过载需求。同时,鸭舵尾迹作用在弹身/尾翼上产生较强的三通道气动耦合问题。通过对鸭舵控制三通道耦合机理的研究,针对鸭舵控制耦合的问题给出工程解决方案。
The canard configuration means that the air rudder is located in the front of the aircraft,compared with normal layout,the canard air rudder has high control efficiency,fast response and large lift drag ratio,it can meet the requirements of strong maneuverability and high overload under the constraint of small outer envelope size of aircraft.At the same time,the canard wake produces a strong three channel aerodynamic coupling problem on the missile body/tail.Base on the three channel coupling mechanism of canard control,the engineering solution to the problem of canard control coupling is given.
