Turboelectric, serial and parallel hybrid-electric and universally-electric aircraft seem to be a potential key technology to allow for synergistically integration of new technologies within the airframe. This is enabled by the separation of the thrust generation devices and the power and energy supply system. This novel integration capability is potentially required to fulfill the ambitious environmental targets set by the European Commission with the Strategic Research and Innovation Agenda (SRIA) or the National Aeronautics Space Administration (NASA) with the NASA N+3 goals. SRIA is aiming a reduction of CO2 by 75% up to the year 2050 compared to the year 2000 and an emission-free taxiing capability for future aircraft concepts. For the purpose of electric taxiing different ground-based and aircraft onboard options are available. In this paper the focus is set on the aircraft systems. Hybrid-electric propulsion systems are already intrinsically enabling electric taxiing in some cases such as electric driven fans. In the presented studies the impact of the so-called in-wheel electric taxiing system is investigated for hybrid-electric and also for a conventional solely kerosene powered aircraft. For these concepts the electric taxiing capability and the potential block fuel saving impacts are identified. Furthermore, the potential usage of the installed system assisting the take-off ground acceleration phase is discussed.
