An analog simulation is given of a turbine alternator system used as a vehicle drive. As in an electrical vehicle drive system, the miles/dollar ratio is a critical consideration. The influence of a load scheduler on the economy of the turbine fuel consumption has been studied. It is shown that by utilizing this load scheduler as a proper sensor of the vehicle's power requirement and controlling the power output of the turbine, a considerable amount of fuel can be saved, especially when the vehicle is at rest and the turbine speed is governed at a lower idling level than its rated operating speed. Also, some general power and torque characteristics resulting from the simulation are given.
