Apart from low pollution and high economy, the driving system must also ensure a satisfactory driving performance and a long driving range. A power density of 100 W/kg and an energy density of 200 Wh/kg are stated as minimum requirements and road vehicle drives. Flywheels help to avoid energy losses, owing to the fact that the driving energy in rotors is available as kinetic energy so that energy conversion becomes unnecessary. Requirements on vehicle flywheel drives are listed. Constructional and operating parameters were compiled and expressed in formulas for the purpose of computer simulation. The mathematical representations are validated by test bench experiments. A parameter study was carried out in order to assess the efficiency of different measures to meet these requirements. Uses of flywheels as vehicle drive elements are listed. (ERA citation 10:000718)
