The invention discloses an aircraft nose cone tip variable-diameter framework rope driving mechanism which comprises a plurality of framework branch chains, a top disc and a bottom table, and each framework branch chain comprises a first framework segment, a second framework segment, a third framework segment, a fourth framework segment, a fifth framework segment and a sixth framework segment; the bottom table is in a step shape and is provided with three layers of circular truncated cones, and the framework branch chains are evenly distributed on the bottom table in parallel. A pulley is arranged in the first segment of the framework and used for fixing the tail end of the steel rope; two pulleys are arranged in each of the second skeleton section, the third skeleton section, the fourth skeleton section, the fifth skeleton section and the sixth skeleton section and are used for positioning the skeleton sections by steel ropes; and a pulley is arranged below each positioning part of the bottom table and is used for ensuring that the position of the initial section of the steel rope is not changed when the skeleton is controlled to move section by section. According to the invention, the diameter of the nose cone can be changed according to different requirements of an airplane on the optimal aerodynamic layout of the nose cone at an ascending section and a reentry section.

    本发明公开了一种飞行器头锥尖端变直径骨架绳驱机构,包括多个骨架支链、顶盘、底台,单个骨架支链包括骨架第一分节、骨架第二分节、骨架第三分节、骨架第四分节、骨架第五分节、骨架第六分节;所述底台呈阶梯形状,设有三层圆台,多个骨架支链并联均布在所述底台上;骨架第一分节内设有一个滑轮用于固定钢绳末端;所述骨架第二分节、骨架第三分节、骨架第四分节、骨架第五分节、骨架第六分节内均有两个滑轮用于钢绳对各个骨架分节的定位;所述底台的每个定位部下方均有一个滑轮用于保证钢绳在控制骨架分节运动时初始段位置不变。本发明可以根据飞机在上升段和再入段对其头锥的最优气动布局的不同要求来对头锥直径进行变化。
