LANDING GEAR FORCE AND MOMENT DISTRIBUTOR

A landing gear force and moment distributor system for an aircraft having a longitudinal axis aligned in a forward-aft direction, a vertical axis perpendicular to the longitudinal axis, and a landing gear including a pair of bogies arranged symmetrically about the longitudinal axis, each bogie having an actuator arranged to brake and/or drive one or more wheels. The force distribution system includes a distribution module arranged to: receive an input demand including a longitudinal force input demand corresponding to a desired braking or driving force along the longitudinal axis for the landing gear and a moment input demand corresponding to a desired moment about the vertical axis for the landing gear; and to use the received input demand to calculate an output command including, for each bogie, a longitudinal force output command corresponding to a braking or driving force along the longitudinal axis to be applied to the bogie.
