Abstract
A system for providing an aircraft with protection against hard landings, the system comprising friction energy absorber systems arranged at the points the aircraft will impact against the ground in the event of a crash. The friction energy absorber system has two energy absorber devices arranged between a base and a cover along two non-parallel deformation axes, a support secured to the base and suitable for moving in translation relative to the cover, and a friction device. The friction device is arranged between the cover and the support and it generates a friction force along a translation axis parallel to a deformation axis such that the energy absorber device, after being plastically deformed during a crash, remains in contact with the support and the cover.
