Abstract
Methods of reducing aircraft noise from landing gear during take off and landing maneuvers. An actuated multi-axle landing gear truck is oriented such that a plane through the axles is substantially parallel to the aircraft water line during approach and takeoff. The embodiment retains the capability to re-orient the truck “toes up” or “toes down,” as may be required, just before touchdown to facilitate rapid application of braking and speed brake/spoiler deployment. It also maintains the capability to re-orient the truck during gear retraction after take off to fit into the aircraft wheel wells. The invention may be retrofitted to existing aircraft or deployed on new aircraft.
