Thread: air propelled vehicle

  1. #1

    Lightbulb air propelled vehicle

    i am designing a vehicle which can be propelled because of thrust provided by a rotating fan...

    currently i am constructing a miniature form..but even in that i am facing a problem that i can't find a suitable fan(max. of 5in dia)
    that can provide sufficient thrust to propel our vehicle.

    i am using a 12 volt brushless dc motor of 15k rpm...

    hey guys where can i get a fan for my need??should i design a suitable blade that will suit my need, if yes then plz tell me the procedure for designing.

    Please dont forget about friction, robot weight, fan weight, battery weight. If you are talking about hovercrafts please clarify.

    designing a suitable blade that will suit your need is itself a big stuff and different branch.
    Eventhough you manage to design it, you will be again here for asking who will make it
    Leave that its a costly affair.

    Don't go to it until and unless it is technical requrement
    The effficiency of such system will be very less

    When you use motor there is only one time power conversion from electrical to useful mechanical rotation and you get work done, And if you use fan then further energy conversion will take place into mechanical to mass momentum of air - Looks horrible

    The best suggesstion i will give you is Go for traditional motorised vehicle

    @prabodh,

    Try RCDhamaka - seems to have a wide range. I havent personally purchased from them so I cant vouch for them.

    Rgds,
