The invention relates to the field of aerospace equipment, and discloses a variable-elongation wing and an aircraft. The aircraft comprises a variable-elongation wing, the variable-elongation wing comprises at least two wing ribs, and all the wing ribs are sequentially arranged in parallel at intervals; the folding mechanisms are arranged between any two adjacent wing ribs, each folding mechanism comprises a locking piece, an elastic piece and two connecting rods, one ends of the two connecting rods are hinged, the other ends of the two connecting rods are arranged opposite to the two wing ribs respectively, one connecting rod at least corresponds to one elastic piece, and the other ends of the two connecting rods are hinged to the locking pieces. The other end of each connecting rod is connected with the wing rib opposite to the connecting rod through the corresponding elastic piece, each connecting rod is hinged to the wing rib opposite to the connecting rod, the elastic pieces are used for enabling the connecting rods to be perpendicular to the wing ribs opposite to the connecting rods, and the locking pieces are used for locking or unlocking the connecting rods and the wing ribs when the connecting rods are perpendicular to the wing ribs. The distance between every two adjacent wing ribs is adjusted through folding of the folding mechanism, so that the variable unfolding wing can reach a higher folding rate.

    本发明涉及航空航天设备领域,公开一种变展长机翼及飞行器。飞行器包括变展长机翼,变展长机翼包括:至少两片翼肋,全部翼肋依次平行间隔布置;折叠机构,任意相邻两片翼肋之间均设置有折叠机构,折叠机构包括锁紧件、弹性件以及两个连杆,两个连杆的一端铰接连接,两个连杆的另一端分别与两片翼肋相对设置,一个连杆至少对应一个弹性件,各个连杆的另一端均通过其所对应的弹性件与其所对的翼肋相连,且各个连杆均与其所对的翼肋铰接连接,弹性件用于使连杆与所对的翼肋保持垂直,锁紧件用于在连杆与翼肋相垂直时锁紧或者解锁连杆和翼肋。通过折叠机构折叠来调整相邻两片翼肋之间的距离能够使变展开机翼达到更高的折叠率。
