A landing gear cabin door retracting and releasing device can be used for opening and closing a landing gear cabin door of a reusable aircraft. The device is characterized by comprising a cabin door actuator and a plurality of sets of connecting rod mechanisms. An independent cabin door actuator is adopted to drive a plurality of sets of four-connecting-rod mechanisms, and the four-connecting-rod mechanism is suitable for an aircraft which is high in flight speed, small in cabin space and provided with a multi-fan-shaped undercarriage cabin door and has the remarkable advantages of being light in weight, small in size, simple in time sequence, good in synchronism and the like. When the undercarriage cabin door is opened in place, the three sets of four-connecting-rod mechanisms are all located near the dead point position, and damage to the cabin door structure caused by over-travel of the actuator can be avoided. The cabin door folding and unfolding device is arranged near the side wall plate and the upper wall plate of the undercarriage cabin, the space requirement is small, and the residual cabin space after the undercarriage is folded can be fully utilized.
一种起落架舱门收放装置,可用于可重复使用飞行器起落架舱门的打开和关闭。其特征在于,包括:一个舱门作动器和多套连杆机构。采用独立舱门作动器驱动多套四连杆机构,适用于飞行速度高、舱内空间紧张、起落架舱门为多扇形式的飞行器,具有重量轻、体积小、时序简单、同步性好等显著优势。起落架舱门打开到位时,三套四连杆机构均处在死点位置附近,可避免作动器超行程导致的舱门结构损坏。舱门收放装置布置于起落架舱侧壁板和上壁板附近,空间需求小,能够充分利用起落架收起后剩余的舱内空间。
