Summary

  • Available electric motor and power-management systems are adequate, however significant technology challenges remain in the development of batteries, fuel-cells, and light weight H2 tanks

  • Battery powered aircraft will require a 10X energy density increase to match Light Utility GA piston performance, but looks like a viable option for Light Primary Trainer aircraft in the near future

  • Several potentially viable approaches exist for electric propulsion- systems and targets for component performance have been identified, but significant development work remains before the best solution is known

  • The rate Electric Aircraft Propulsion technologies are advancing is encouraging and holds the promise of new more capable aircraft in the near future.
