ABSTRACT:
An integrated propulsion and guidance system for a vehicle includes an engine coupled to an impeller via a driveshaft to produce propulsive force. The impeller includes a hub and a plurality of blades, including at least one control blade pivotably mounted to the hub. A control system provides a control signal to a magnetic actuator to adjust the blade pitch of the control blades as the blades rotate about the hub. The change in blade pitch produces a torque on the driveshaft that can be used to control the heading of the vehicle.
