Abstract

A variable marine jet propulsion system incorporates a motor (21), variable pitch propeller pump (50) in a spherical housing (62), a variable housing and a variable inlet duct, and a microcontroller (140). The pump, nozzle, and inlet are controlled by the microcontroller, which is programmed to control the pump as a continuously variable power transmission for maintaining efficient motor operation, the nozzle for maintaining efficient pump operation, and the inlet for maintaining efficient recovery of the total dynamic head of the incoming water. The spherical pump housing maintains close fits to the propeller vane tips for more efficient operation at all pitches, including zero and reverse pitches. Zero pitch results in no effective pumping action, effectively a true neutral in fluid power transmission. Reverse pitch in combination with the large variable nozzle provide reverse flow and consequently reverse thrust, which eliminates the need for a backing bucket.
