Beschreibung
Zusammenfassung:	A marine propulsion unit, including a duct and a center body which is located within the duct. A combustion chamber is positioned in the center body and receives fuel and compressed air from a source located in the hull of the ship. A turbine also positioned in the center body drives an impeller at the inlet of the duct. Wing shaped arms extend laterally of the duct with each arm having a span-wise nozzle so that water can flow through the lateral arms. The exhaust of the turbine flows through the arms and is mixed with the water flowing through the nozzle. The direction of the efflux from the nozzle can be varied to provide thrust vectoring.
