Abstract
Skid landing gear provided with components having a device for absorbing energy by plastic deformation and/or for limiting stress, and components of this type. According to the invention, each of two undercarriage parts comprises a skid 170 connected to the structure to two crosspieces 175 and 176 that are hinged on the structure about an axis parallel to the hinge axis on the structure of the other crosspiece of the same undercarriage part, and at least one component 181 that has a main mechanical and/or hydraulic function, such as a strut, a cross-bracing or control jack, a shock absorber or a shock absorber jack, the component being provided with a device for absorbing energy by plastic deformation and/or for limiting stress, and is connected on the one hand to a crosspiece 176 of the respective undercarriage part and on the other hand either to the corresponding skid 170 or to the structure of the aerodyne. The invention is especially suited to use on helicopters.
