The invention relates to an undercarriage folding and unfolding and cabin door opening and closing actuation system, and belongs to the technical field of aircraft undercarriage control equipment. Comprising an undercarriage folding and unfolding actuator, two cabin door folding and unfolding actuating cylinders and two self-sealing joints, the undercarriage folding and unfolding actuator is axially and horizontally arranged; the two cabin door folding and unfolding actuating cylinders are symmetrically arranged on the two sides of the undercarriage folding and unfolding actuator. The two cabin door folding and unfolding actuating cylinders are parallel to the axial direction of the undercarriage folding and unfolding actuator; each cabin door folding and unfolding actuating cylinder is connected with an undercarriage folding and unfolding actuator through a self-sealing joint; the two cabin door retracting and releasing actuating cylinders are divided into a first cabin door retracting and releasing actuating cylinder and a second cabin door retracting and releasing actuating cylinder according to left and right positions; the first cabin door retraction actuating cylinder is positioned on the left side; the second cabin door retraction actuating cylinder is positioned on the right side; correspondingly, the self-sealing joint is divided into a first self-sealing joint and a second self-sealing joint; the problems that an undercarriage folding and unfolding system adopting a local hydraulic source is multiple in hydraulic pipeline and low in integration level or cannot control opening and closing of a cabin door at the same time are solved.
本发明涉及一种起落架收放及舱门启闭作动系统,属于飞行器起落架控制设备技术领域;包括起落架收放作动器、2个舱门收放作动筒和2个自封接头;起落架收放作动器轴向水平放置;2个舱门收放作动筒对称设置在起落架收放作动器的两侧;2个舱门收放作动筒与起落架收放作动器的轴向平行;每个舱门收放作动筒分别通过1个自封接头与起落架收放作动器连接;2个舱门收放作动筒按左右位置分为第一舱门收放作动筒和第二舱门收放作动筒;第一舱门收放作动筒位于左侧;第二舱门收放作动筒位于右侧;对应的,自封接头分为第一自封接头和第二自封接头;本发明解决了采用局部液压源的起落架收放系统液压管路较多、集成度较低,或不能兼具控制舱门的启闭等问题。
