Abstract
A reversing marine drive utilizing a gas generator prime mover provided with first and second counter-rotating power turbines. The first turbine is connectable by a differential gear set and a pinion and reduction gear assembly to the ship's shaft to drive the shaft and the screw thereon in the forward thrust direction. The second turbine is connectable by the differential gear set and the pinion and reduction gear assembly to the ship's shaft to drive it and the screw thereon in the reverse thrust direction. A brake assembly is provided in association with each of the first and second power turbines so that when one of the power turbines is driving the screw, the other power turbine is stopped. A master computer may be provided to control the reversing marine drive.
