Abstract
A landing gear provided with at least two first rollers mounted on two first free-wheels respectively connected to a first skid and configured, during a landing phase, to lock in the elastic return direction when the first skid moves in a first direction from the first skid towards a second skid and to be free in the sink direction during movement in a second direction, at least two second rollers being mounted on two respective second free-wheels connected to a second skid and configured, during a landing phase, to lock when the second skid moves in the second direction and to be free during movement in the first direction.
Claims18
A landing gear provided with a first skid and a second skid,
- wherein the landing gear comprises at least two first ground-contact rollers mounted on two respective first free-wheels that are connected to the first skid, each first free-wheel being configured to lock during an elastic return phase when the first skid moves in a first direction and to be free during a sink phase when the first skid moves in a second direction opposite the first direction, the first direction extending from the first skid towards the second skid, the landing gear comprising at least two second ground-contact rollers mounted on two respective second free-wheels that are connected to the second skid, each second free-wheel being configured to lock during the elastic return phase when the second skid moves in the second direction and to be free during the sink phase when the second skid moves in the first direction.
A method for limiting the bounce of the landing gear during a landing phase, the landing gear being provided with a first skid and a second skid, the method comprising:
- during a landing phase, positioning at least two first ground-contact rollers mounted on two respective first free-wheels connected to the first skid in landing positions preventing the first rollers from moving towards the second skid, and positioning at least two second ground-contact rollers mounted on two respective second free-wheels connected to the second skid in landing positions preventing the second rollers from moving towards the first skid;
- and
- during a phase following the landing phase, positioning the at least two first rollers and the at least two second rollers either in respective rolling positions allowing the landing gear to slide on the ground or in respective braking positions preventing the landing gear from sliding on the ground.
