The invention discloses an aircraft nose landing gear which comprises a buffer strut, the top end of the buffer strut is connected to an aircraft body connector, the bottom end of the buffer strut is connected to a front aircraft wheel, the front aircraft wheel is of a double-row wheel structure, and each row of wheels can independently rotate; the landing gear further comprises a turning actuating cylinder which is a push-pull type double actuating cylinder and is connected to the middle section of the buffer supporting column; a retractable actuating cylinder, wherein one end of the retractable actuating cylinder is connected to the top end of the buffer supporting column; an inclined supporting column which is connected between the other end of the retractable actuating cylinder and the middle section of the buffer supporting column; and an uplock which is connected to an aircraft fuselage joint through a bolt and is used for locking the nose landing gear in the folded state. The nose landing gear of the aircraft can effectively reduce the torque required for turning and increase the output turning torque.

    本发明公开一种飞机前起落架,包括:缓冲支柱,缓冲支柱的顶端连接于飞机机身接头,缓冲支柱的底端连接于前机轮,前机轮为双排轮结构,每排轮均能够独立自转;转弯作动筒,为推挽式双作动筒,连接于缓冲支柱的中段;收放作动筒,收放作动筒的一端连接于缓冲支柱的顶端;斜支柱,连接于收放作动筒的另一端和缓冲支柱的中段之间;上位锁,通过螺栓连接于飞机机身接头,用于将收起状态的前起落架锁住。本发明所述飞机前起落架能够有效降低转弯需求力矩,增加输出转弯力矩。
