ABSTRACT:
A mixed propulsion system comprising a turbine unit having two output shafts which drive two counter rotating flywheels and, via a reduction gearbox, two generators which generate electricity to drive two electric drive motors the output shafts of which are connected to the wheels of the vehicle. A control system is provided, linked to the accelerator and brake pedal of the vehicle, for controlling the excitation of the field windings of the generators and the motors such that a predetermined excitation pattern is followed. The turbine unit is automatically controlled to run when the speed of the flywheels falls below a lower threshold value and is turned off when the flywheels reach a predetermined maximum threshold speed.
