An efficient passive no-fuel consuming underwater propelling vehicle engine operating only on electricity has been developed and studied in this research. The engine is housing a propeller fan, a compressive body housing a 75KWh rechargeable battery pack, 4 pole 3 phase Induction motor, inverter and a single speed transmission 9.73:1 gearbox connected to the driving shaft which in turn drives the turbine at the outlet. The turbine being coaxially connected to the motor acts like a generator generating around 69KW during braking of vehicle through regenerative braking which is in turn used to charge the battery pack. The power thus generated by the motor is transmitted to the shaft producing around 5990 RPM, accounting all losses. The theory and concept are derived from the working principle of a scramjet engine, air breathing engine and an Electric Vehicle. The velocity achieved by the vehicle catering all losses and drag at its peak working condition is calculated around 66.87 m/sec, almost double to that of the speed of conventional underwater running vehicles. Demonstrates Design of Engine; Demonstrates Design Calculations; Demonstrates output parameters of Engine.
