飞翼布局取消了常规的垂尾和方向舵,存在较严重的航向操纵与控制问题,需要重点掌握偏航操纵舵面的配置特点与操纵特性.针对飞翼布局最常采用的两种阻力类偏航操纵装置:开裂式方向舵和嵌入面,介绍了研究现状、受力特点,利用数值仿真方法,详细分析了偏航操纵特性、三轴操纵耦合特性以及对气动特性和稳定特性的影响规律,对比了这两种舵面在操纵特性方面的共同点和差异性,并揭示了内在的影响机理.可为解决飞翼布局偏航操纵问题以及阻力类偏航操纵装置的工程化应用提供基础.
The flying wing layout cancels the conventional tail and rudder, which poses serious problems of heading control and control, and needs to grasp the configuration characteristics and steering characteristics of the yawing control surface. For the most commonly used two types of resistance profiles The navigational devices: rupture rudder and embedded face are introduced. The research status and force characteristics are introduced. By using numerical simulation method, the influence of yaw maneuvering characteristic, triaxial maneuvering coupling characteristic and aerodynamic characteristics and stability characteristics are analyzed in detail. The commonalities and differences between the two control surfaces in steering characteristics and their inherent mechanisms are revealed, which can provide a basis for solving the yaw steering problem of wing layout and the engineering application of drag-yaw control devices.
