AIRCRAFT LANDING GEAR LONGITUDINAL FORCE CONTROL

摘要

An aircraft landing gear longitudinal force control system for an aircraft having landing gears with braking and/or driving wheel(s). The system includes an error-based force controller having feedback for minimising any error between the demanded force and the actual force achieved by the force control system. The feedback may be derived from force sensors on the landing gear for direct measurement of the landing gear longitudinal force. The force control system may include an aircraft level landing gear total force controller and/or a landing gear level force controller for each actuated landing gear.

1. A landing gear force control system for an aircraft having a longitudinal axis and a plurality of landing gears having one or more braking and/or driving wheels, the force control system comprising an error-based force control module adapted to:
receive an input signal representative of a longitudinal force demand to be achieved by the force control system; receive an input signal representative of an actual measured longitudinal force acting upon one or more landing gears; calculate any error between the force demand signal and the actual force signal; and output a longitudinal force command for the one or more landing gears so as to minimize any error between the demanded force and the actual force.
