The invention discloses a high-environment-adaptability rudder wing folding and unfolding locking structure and a design method.The unfolding locking structure comprises a movable rudder surface and a fixed rudder surface of a rudder wing, an unfolding mechanism and a locking mechanism, the fixed rudder surface is connected with an aircraft through a rudder shaft, and the fixed rudder surface is provided with an arc profile surface; the root of the movable control surface is an arc inner surface and coaxially wraps the arc outer surface, and the fixed control surface can rotate relative to the movable control surface; a torsion bar is arranged in the unfolding mechanism, and the two ends of the torsion bar are connected to the movable control surface and the fixed control surface respectively; the locking mechanism comprises a locking pin and a limiting pin which are elastically arranged in the movable control surface, a locking pin hole and a limiting pin hole which are matched with the locking pin and the limiting pin are formed in the fixed control surface, and the width of the limiting pin hole is larger than that of the locking pin hole. The use performance of the folding rudder in severe environments such as deserts, gobi and sand dunes is improved, and the folding rudder can be popularized and applied in a large-load high-heat-flow environment.
本发明公开了一种强环境适应性舵翼折叠与展开锁紧结构及设计方法,其中所述展开锁紧结构包括:舵翼的动舵面及定舵面、展开机构和锁紧机构,其中:定舵面通过舵轴与飞行器连接,定舵面具有圆弧外形面;动舵面的根部为圆弧内形面且同轴包覆在所述圆弧外形面的外部,定舵面可以相对于动舵面旋转;展开机构中设置有扭杆,扭杆的两端分别连接至所述动舵面和定舵面;锁紧机构包括弹性设置于动舵面中的锁紧销和限位销,在定舵面上设置有与所述锁紧销和限位销配合的锁紧销孔和限位销孔,限位销孔的宽度大于锁紧销孔。本发明提升了折叠舵在荒漠、戈壁、沙丘等恶劣环境下的使用性能,可在大载荷高热流环境中推广应用。
