Abstract
An aircraft drive system having a fully electric speed-proportional control and drive system for the nose wheel of an aircraft in which variable steering authority is accomplished by monitoring of the signal from a tiller and rudder pedals by a nose wheel controller in conjunction with the speed of the aircraft, in order to command and power an electromechanical steering, actuator to achieve speed-proportional variable steering authority. This provides a system with a quicker response time than current hydraulic-based systems which can help reduce nose wheel shimmy, eliminate certain nose wheel steering failure modes associated with hydraulic systems, and reduce weight when used in small-to-medium sized aircraft.
