Future flying car technology?

    Hello.

    When people started flying it was quite bumpy because of turbulence below 10000 meter.
    So todays air travel is mostly above 10000 meter to avoid a bumping turbulent ride.
    To develop a future flying car this must be dealt with because people dont want to be thrown around in the cockpit when flying to the shop and for a short flight it is not possible to get to 10000 meter to avoid turbulent air.

    So to deal with this the future aeroplane need to adjust for turbulent air and that is to separate the lifting and pulling propeller from the cockpit with wires.

    That solve some problems and create some new.

    When you get in to your flying car then the start noice and wind turbulence is minimal because the engine and propeller start first, because it now has a lower weight

    So it take off first and is hoovering above the cockpit.
    When the cockpit is pulled of the ground it can be very stabile,
    because you now can adjust the wires from the top engine system

    When you fly through the air the engine system can be lets say 100 meter in front, pulling the cockpit.
    The front engine system can detect and with sensors adjust the wires so that the cockpit can move through the air with no turbulence or bumps in the flight.

    This is probably the future technology of flying cars.

    BTW, the technology you are proposing could be used by commercial airliners as well. There is no need to have the whole propulsion package fly ahead of the passenger compartment -- just propose some sensor package that is pushed ahead of the plane on a boom to sense the turbulence. Then you are left with figuring out how far to push it ahead to get good advanced notice of the turbulence to help your plane control surface algorithm.

    What do you think about this system.

    Would anyone like to see my simulation system and radio controlled modells of it?

    Sounds like guaranteed motion sickness; getting a fine-grained enough sensor suite to "know" not only what the sensors are flying through, but where and what that particular air-mass will be and be doing when the passenger pod reaches it, plus anticipating what unsampled air masses are going to be doing seems a bit ambitious.

    I'm not really sure I follow your post,but I think you're talking about gust alleviation.

    Gust alleviation is already in use on most (all?) fly-by-wire aircraft. It's based on a feedback control system that senses normal acceleration and identifies turbulence by comparing the measured acceleration to the commanded acceleration. Control surfaces (elevator, ailerons, flaps) are then deployed to reduce the gust response.

    Separating the propulsion/lift system from the cabin is unnecessary and possibly even counter-productive, as it can introduce structural vibrations that aggravate the turbulence response.
