Abstract: The invention relates to an aircraft (5) comprising: a structure (6); a landing gear (1) mounted on the structure (6) of the aircraft; and at least one obstacle detector (2). The aircraft (5) is characterized in that the obstacle detector (2) is secured to an arm (3), said arm (3) being mounted on the structure (6) such that it can move between a rest position in which the arm (3) is retracted and a detection position in which the arm (3) is deployed such that the obstacle detector (2) extends close to a lower portion of the landing gear (1) at a distance from the structure (6) of the aircraft (5).

Abstract: An aircraft undercarriage comprising a telescopic linear rod (0, 0′, 0″) comprising first and second sliding rod portions. The undercarriage further comprises: a first permanent magnet set (1a, 1a′, 1a″) fastened to the first rod portion (1, 1′, 1″); and a second permanent magnet set (2a, 2a′, 2a″) fastened to the second rod portion (2, 2′, 2″); the first and second permanent magnet sets (1a, 1a′, 1a″, 2a, 2a′, 2a″) generating a magnetic repulsion force between the first rod portion (1, 1′, 1″) and the second rod portion (2, 2′, 2″) and maintaining a first annular space (E1) between the first rod portion and the second rod portion.
