The invention belongs to the technical field of aviation, and particularly discloses a closing and locking mechanism for a popping opening of a folding airfoil of a small aircraft. A plurality of airfoils are arranged on one side, facing a limiting flange, of an airfoil mounting seat at intervals in the circumferential direction; the airfoils can rotate around the corresponding pin shafts to penetrate through the corresponding airfoil windows to be unfolded or folded, supporting shafts are arranged on the two sides of each airfoil between the airfoil mounting base and the limiting flange respectively, a torsional spring is arranged at the end, close to the airfoil mounting base, of each supporting shaft in a sleeving mode, a sealing plate is arranged on each supporting shaft in a sleeving mode, and the sealing plates are arranged on the sealing plates in a sleeving mode. Under the action of the airfoil and the torsional spring, when the airfoil is unfolded, the sealing plate can rotate around the supporting shaft to be tightly attached to the inner surface of the shell to close the airfoil window, and when the airfoil is folded, the sealing plate can rotate around the supporting shaft to be tightly attached to the two sides of the airfoil, quick response, respective positioning and reliable locking are achieved, and folding, unfolding and locking after unfolding in place can be repeatedly achieved. The structure is simple, compact, safe and reliable.

    本发明属于航空技术领域,具体公开一种小型航空器折叠翼面弹出口的封闭和锁定机构,在翼面安装座朝向限位法兰的一侧沿周向间隔设置有若干个翼面,在驱动机构的作用下,所述翼面能够绕对应的销轴转动穿过对应翼面窗口展开或收起,在翼面安装座和限位法兰之间每个翼面的两侧分别设置有支撑轴,在每个支撑轴临近翼面安装座的一端分别套设有扭簧,在每个支撑轴上分别套设有密封板,在翼面和扭簧的作用下,翼面展开时,密封板能够绕支撑轴旋转紧贴壳体内表面将翼面窗口封闭,翼面收起时,密封板能够绕支撑轴旋转紧贴在翼面两侧,快速响应,分别定位及可靠锁紧,能够反复实现收起、展开、及展开到位后锁定,结构简单紧凑,安全可靠。
