Abstract: Turbine powered, self-propelled vehicles utilizing multiple electric motors in sets to comprise part of a novel modular electric powertrain drive system. This novel powertrain system is particularly applicable to larger weight class tracked military vehicles, such as an M-1 tank. However, other large or smaller weight class turbine powered vehicles, are candidates including both track and wheel driven types, as well as certain airborne type vehicles such as helicopters and ground-effect vehicles. The modular powertrain drive system hereof basically comprises a plurality of electric high speed drive motors and also of electrical power generator devices, such as alternators, arranged to be commonly driven by the turbine's effective output shaft.
