The invention provides a frame type undercarriage, an aircraft and a storage method of the undercarriage. The frame type undercarriage comprises an outer cylinder, a piston rod stretching out and drawing back at one end of the outer cylinder, a buffer used for driving a frame to rotate anticlockwise or clockwise and a rotation driving device used for driving the piston rod to rotate to the angle alpha in the outer cylinder, and the end of the piston rod is connected with the frame through a rotation hinge point C; a fixed hinge point A and a movable hinge point B are arranged at the end, away from the piston rod, of the outer cylinder, and the retractable device is arranged close to the fixed hinge point A. The retractable device stretches out and draws back to drive the undercarriage to rotate anticlockwise or clockwise. According to the folding landing gear, by means of two times of folding, all parts on the landing gear form the minimum storage state, the space occupied by the landing gear during storage is greatly reduced, and the space utilization rate of an aircraft is increased.

    本发明提供一种车架式起落架、飞机及起落架的收纳方法。所述车架式起落架包括外筒、伸缩于所述外筒一端的活塞杆、用于驱动车架逆时针或顺时针转动的缓冲器、用于驱动活塞杆在外筒中转动至角度α的旋转驱动装置,所述活塞杆的端部通过转动铰点C连接有车架,所述外筒远离活塞杆的一端设有固定铰点A和活动铰点B,所述收放装置靠近固定铰点A设置,所述收放装置伸缩以驱动起落架逆时针或顺时针转动。本发明通过两次次折叠的方式,将起落架上的各零部件形成最小的收纳状态,大大减少了起落架收纳时占用的空间,提高飞机空间利用率。
