Abstract: A turret drive system for mobile and armored vehicles includes a turbo-geator for supplying power to an electric motor. The driveshaft of the motor is connected to the driveshaft of a rotary amplifier, with a flywheel mounted to the interconnecting driveshaft. The flywheel stores kinetic energy which is delivered via the amplifier to a D.C. motor which in turn drives the turret through gearing members. A portion of the large energy reservoir in the flywheel may be instantly transferred to the turret by suitable control signals, resulting in high instantaneous power being developed to drive the turret and consequent improvement of performance of weapons mounted in the turret. The system also provides regulated electric power for ancillary vehicle equipment.
