Abstract: An aircraft undercarriage having a strut (1) hingedly mounted to the aircraft, and a bottom part (2) carrying the wheels and movable relative to the strut. The bottom part has a rod that slides in the strut and a scissors linkage between the strut and the rod. The undercarriage has a shortener for shortening the undercarriage between a deployed position and a raised position by causing the rod to enter into the strut (1). The shortener has coupled first and second members (11, 12), the first member (11) coupled to the bottom part (2) or to an element (5) that moves with the bottom part during its movement relative to the strut. The second member (12) is hinged to the aircraft so that while the undercarriage is raised, the second member abuts before the undercarriage reaches the raised position. The first member (11) is coupled to the scissors linkage.

Abstract: An aircraft undercarriage comprising a strut (1) designed to be mounted in hinged manner to a structure of the aircraft, and a bottom portion (2) carrying the wheels and movable relative to the strut, the undercarriage also including an undercarriage shortener device for shortening the undercarriage between a deployed position and a raised position, said device comprising first and second members (11, 12) coupled to each other, the first member (11) being coupled to the bottom portion (2) of the undercarriage or to an element (5) that moves together with said bottom portion during movement of said bottom portion relative to the strut, while the second member (12) is hinged to the structure of the aircraft in such a manner that while the undercarriage is being raised, the second member comes into abutment before the undercarriage reaches the raised position.
