Aircraft Electric Taxi Demonstration

by John White |  | 2 comments

In the following video it shows an Airbus moving around the ramp supposedly utilizing an electric motor. I must admit that I am a bit of a skeptic about this video, but would like to see some comments below as to what YOU think: I am not willing to say it is impossible, but it seems to me it would take one heck of a large electric motor to move such a large aircraft, particularly as easily as this one appears to move. The following photograph shows the wheel axle and motor: Electric Motor On Wheel Axle Of Airbus Electric Taxi Demonstration When you consider the size and mass of tugs used to move these aircraft into and out of parking one must wonder how some small motor can so easily move an aircraft of this size with such seemingly little effort. Most likely this is a spoof, but I leave it up to you to decide. Please leave a comment below and let me know what YOU think! In the meantime keep your wings straight and level Hersch!

    Seems to me that conventional tow trucks or tugs only need their mass to have sufficient grip in order to get a 50 to 400 tonnes aircraft rolling and to get it stopped.
    The great benefit of this system is that the mayority of the aircraft mass is already pushing down on the driven wheels and also an electric motor has better torque development at low rpm’s (easier and smoother to control the taxi speed).
    Of course there is a weight penalty to be paid when in the air, but the reduce of polution, taxi-fuel costs and FOD risk could give an outcome favoring the new system.
    Considering costs and polution, the benifits seem to be higher on short-/medium haul routes (more relative taxi time to airborne time).

    Now all we need is an electric groundloop system so groundcontrol can guide us after vacating the RNW to the terminal without incidents :-)

    Very curious how this system might evolve………..

    This is not a spoof. I spoke with an engineer about other test and they were able to push the aircraft backward while the main engines were in forward idle thrust. This demonstrates the capability of axial flux electric motors to provide the high torque density to conduct ground maneuvering of aircraft; in fact L-3 is gearing up the manufacturing of these electric motors in Michigan for use in an electric taxiing system and the retrofit of aircraft will be conducted by Lufthansa Technik.
