ABSTRACT:
The invention is directed to an improved water jet propulsion system for a marine vehicle. The water jet propulsion system of the present invention incorporates an unconventional and compact design including a short, steep, hydrodynamically designed inlet duct adapted for mounting to the surface of the vehicle hull and extending internally thereof, a water jet pump having an inlet end attached to the outlet end of the inlet duct, a motor for rotating the pump impeller, a drive shaft located completely outside of the flow path connecting the motor with the pump impeller, a flow passage for discharging accelerated flow received from the pump in a generally rearward direction, and a steering and reversing mechanism pivotably mounted about a substantially vertical axis to the aft portion of the vehicle hull for redirect accelerated flow received from the outlet nozzle so as to provide maneuvering capability to the vehicle.
