针对无尾布局航向控制问题,提出了嵌入式阻力舵与襟副翼组合的航向组合式操纵舵面,结合300座级翼身融合布局大型客机设计方案进行了舵面设计和风洞试验研究。结果表明,单独嵌入式阻力舵在提供航向控制力矩的同时,耦合了更大的滚转力矩和侧力,需解耦消除;采用组合式舵面,不仅可提供更大的航向控制力矩,同时减缓甚至消除了耦合滚转和侧力。在某些舵面组合状态,有实现十分理想的纯航向操纵模式的可能。组合式舵面为解决无尾布局飞机的航向控制问题提供了一条崭新的技术途径,具有广阔的工程应用前景。
Aiming at the heading control problem of tailless layout, a combination course control rudder with embedded resistance rudder and flaperon is proposed. The design of rudder surface and the wind tunnel experiment are studied with the design of 300-seat large-wing passenger aircraft. The results show that the single embedded resistance rudder can not only provide more heading control torque, but also decoupling and elimination, while providing the heading control torque while coupling larger rolling moment and side force. Meanwhile, Slow down or even eliminate coupling roll and side force. In some combinations of rudder surfaces, there is the possibility of achieving a very ideal pure heading control mode. Combined rudder surface to solve the problem of heading control of aircraft without tail layout provides a new technical approach, has a broad engineering application prospects.
