System layout considerations for turbo-generator based hybrid vehicles

This contribution describes the turbo-generator concept which aims to replace the conventional internal combustion engine. The turbo-generator comprises a small gas turbine engine directly driving a high speed generator. The installation aspects of the turbo-generator in motor vehicles are also described. Assessment of gyroscopic moments for this application is presented using theoretical and numerical calculations. A preliminary predictive assessment is also presented to characterise the effect of rate of change of pitch, roll, and yaw on a small turbogenerator based powertrain for a prospective hybrid vehicle.
