Claims7
An aircraft comprising at least one undercarriage having a leg provided at its bottom end with a rocker arm carrying at least two axles, including one in front of a hinge between the rocker arm and the undercarriage and the other behind said hinge,
- the undercarriage being characterized in that one of the axles is fitted with one or more braked wheels and the other axle is fitted with one or more motor-driven wheels, and
- the undercarriage including a rocking shock absorber coupled between the leg and the rocker arm, a length of the rocking shock absorber varying so as to cause the application of a force to the hinge in order to press the motor-driven wheels against the ground and to increase the load on the motor-driven wheels so as to increase an effectiveness of the motor-driven wheels in moving the aircraft on the ground without help from engines of the aircraft.
A method of taxiing of an aircraft comprising at least one undercarriage having a leg provided at its bottom end with a rocker arm carrying at least two axles, including one in front of a hinge between the rocker arm and the undercarriage and the other behind said hinge,
- one of the axles being fitted with one or more braked wheels and the other axle being fitted with one or more motor-driven wheels,
- the undercarriage including a rocking shock absorber that is coupled between the leg and the rocker arm, the rocking shock absorber having length which varies,
- the method including the step of adjusting the length of the rocking shock absorber so as to cause the application of a force to the hinge in order to press the motor-driven wheels against the ground and to increase the load on the motor-driven wheels so as to increase an effectiveness in moving the aircraft on the ground without help from engines of the aircraft.
