Aircraft comprising a landing gear with controlled detachment in the event of an accident

On an aircraft, particularly of the commercial type, a landing gear (16) placed in front of a fuel tank (18) comprises a rod system (32) capable of coming into contact with a sliding rail (52) formed on a reinforced structural part (48) of the aircraft, in the event of accidental tilting of the gear to the rear. The deformation resulting from the rod system (32) then successively induces the complete slackening of the damper (24) of the gear, the rupture of its slack limit stop (25), followed by the rupture of a part of the rod system (32). The lower part of the gear (16) is then ejected and guided by a rear part (52b) of the sliding rail (52), with no risk of perforation of the tank (18).
