STUDY OF LIGHT WEIGHT TURBINE TRANSMISSION SYSTEMS

Several transmission systems that are applicable to advanced marine vessels were investigated to determine if drives other than right-angle gearboxes would be practical in transmitting 50,000 (37.3 MW) hp from dual gas turbines downward through a vertical distance of 20 (6.10M) ft to a propeller drive shaft. These systems included; hydraulic power, chain drive, steel tape drive, and a slider crank drive. Results of this survey indicated the right-angle bevel gear drive was the optimum system considering our present state-of-the-art. Further investigation was performed to optimize turbine and gearbox arrangement using weight, reliability, efficiency, serviceability, technical risks, and relative cost as the determining factors.
