摘要: 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.

Abstract: Flying wing configuration eliminates conventional vertical tail and rudder, thus existing severe problem on yawing control. To make the configuration into practical use, it is necessary to gain an extensive understanding on the collocation features and control characteristics of yawing control devices. The current research and mechanical features of the two different kinds of yawing control devices, split drag rudder and upper surface spoiler, which are most commonly used on flying wing configuration, were introduced. Using numerical calculation, the yawing control characteristics, three-axis control coupling effect, and influencing regularities on aerodynamic and stability were analyzed. Meanwhile, the common points and differentials on aspect of control characteristics were compared. The conclusions can help to solve the yawing control problem for the flying wing configuration, and help to provide basis on engineering application for the drag yawing control devices.
