Abstract
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.
Claims25
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 is operative at landing gear level and comprises 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 measure of all 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.
A method for directly controlling at a landing gear level a force produced by one or more aircraft landing gears equipped with braking and/or driving wheels, the method comprising:
- receiving an input signal representative of a longitudinal force demand to be achieved by one or more landing gears;
- measuring all forces in the aircraft longitudinal direction acting upon one or more landing gears;
- calculating any error between the demanded force and the actual force;
- and
- outputting a corrected longitudinal force command for the one or more landing gears so as to minimize any error between the demanded force and the actual force.
