Need help on Aluminum propeller

  1. Feb 17, 2007 #1
    I need to contact who ever would be authority on propeller design and applications.

    In short, the Idea is to build a Aluminum prop, 1.2 meters diameter with weight of about 1000 grams. Targeted application would be primarily for powered para gliders. I need some arguments for and against before it leaves blueprint stage.

    If you can point me in the right direction as to who the best contact for me would be, I would be ever so grateful.

    If any of you have experiance on the issue, comments are more than welcome.

    I'm afraid that I can't help you with that. It does seem to me, however, that you'll have to have an awfully thin blade to keep the weight that low with metal.

    Design calls for 1mm thick Al aloy 6063-T6 "skin" with internal rib support in order to achieve desired weight yet maintain the integrity needed for the application.

    Ahhhh...
    I thought that you were talking about milling or casting one. Still can't help you, but it makes more sense now.

    Yup, casting would be production method. Thanks anyway.

    I am sorry for double post guys... do not reply here any more, live thread is: https://www.physicsforums.com/showthread.php?t=156830
