The invention discloses a telescopic wing structure driven by SMA. The telescopic wing structure comprises a fixed wing and a movable wing. The fixed wing comprises a front spar, a rear spar, N fixedwing ribs and a fixed skin; the movable wing comprises a front sliding rod, a rear sliding rod, a linkage mechanism, (2M+1) movable wing ribs, M inner skins and (M+1) outer skins; a rhombic telescopicframe is adopted in the linkage mechanism, and a first SMA wire is arranged between each set of width hinge points moving in the direction perpendicular to the telescopic direction of the linkage mechanism; and a plurality of groups of second SMA wires are arranged between the first movable wing rib and the Nth fixed wing rib. The first SMA wire and the second SMA wire serve as driving sources, adifferential driving mode is adopted, the overall span of the wing is changed by controlling stretching and retracting of the movable wing, the structure is simple, and use is convenient.
本发明公开了一种SMA驱动的伸缩机翼结构,包含固定翼和活动翼;固定翼包含前翼梁、后翼梁、N个固定翼肋和固定蒙皮;活动翼包含前滑杆、后滑杆、联动机构、2M+1个活动翼肋、M张内蒙皮、以及M+1张外蒙皮;联动机构采用菱形伸缩架,在其每组在垂直于其伸缩方向上运动的宽度铰接点之间均设置第一SMA丝;在第1个活动翼肋和第N个固定翼肋之间设置若干组第二SMA丝。本发明以第一、第二SMA丝作为驱动源,采用差动驱动模式,通过控制活动翼的伸缩,实现机翼整体跨度的改变,结构简单,使用方便。
