摘要： A damper for an airplane landing gear leg comprises a main strut (11) and a rod piston (13) co-operating with the strut (11) to define a main chamber (15) and annular chamber (16) for hydraulic fluid, and presenting internally two adjacent chambers (19, 20) that are isolated from each other by a separator piston (21). The damper (10) further comprises a first secondary strut (26) telescopically Slidable on the above-mentioned rod piston (13), and a second secondary strut (37) telescopically slidable on the other end of the first secondary strut (26). The two second annular chambers (31, 40) as defined in this way are respectively connected to associated control circuits thus enabling the total length of the damper to be shortened or lengthened respectively for the purpose of causing the landing gear to contract or to be extended.

摘要： Retractable landing gear for an aircraft, the landing gear being of the type that is raised vertically, and comprising a plurality of independent legs, each leg comprising a structural part rigidly secured to a structure of the aircraft, a pivoting rocker beam supporting a pair of wheels, and a shock absorber. In accordance with the invention, the shock absorber of each leg is extended by a positioning portion enabling the total length of the extended shock absorber to be shortened in order to collapse the leg, and each leg further comprises a positioning actuator connected in hinged manner to the extended shock absorber and arranged to lengthen relative to a normal use position in order to lengthen the corresponding leg. This makes it possible to shorten and/or lengthen one or another of the legs of the landing gear while the aircraft is stationary or taxiing slowly.
摘要翻译：用于飞机的伸缩起落架，起落架是垂直升起的类型，并且包括多个独立的腿，每个腿包括刚性地固定到飞行器的结构的结构部分，支撑一对车轮和减震器。根据本发明，每个腿的减震器通过定位部分延伸，使得能够缩短延伸的减震器的总长度以使腿部折叠，并且每个腿部还包括定位致动器，其以铰接方式连接到延伸的减震器并且被布置成相对于正常使用位置延长，以便延长相应的腿部。这使得可以在飞行器静止或滑行缓慢的情况下缩短和/或延长起落架的一个或多个腿部。
