摘　　要：某简洁气动布局面对称飞行器具有大升阻比、横侧向通道强耦合的特性。分析了该面对称飞行器横侧向通道耦合控制的机理,构建了飞行器横侧向通道系统的模型,进行了气动与控制一体化设计,推导了LCDP稳定性判据参数的约束条件,结合典型飞行状态进行了仿真分析。仿真分析结果表明,仅用一对水平舵面可以实现面对称飞行器横侧向通道的稳定。A concision plane symmetric aircraft has the characteristics of high lift drag ratio and strong coupling between lateral-directional channels.This paper analyzes the coupling control mechanism of lateral-directional channels of the symmetrical aircraft,constructs the system model of lateral-directional channels,carries out the integrative design of aerodynamic and control,and derives the LCDP stability criterion parameter constraint condition.The simulation analysis is carried out with a specific example.The results show that the lateral-directional stability of the symmetrical aircraft can be achieved only by using a pair of horizontal control surfaces.
