    Airfoil Size calculation?

    No rules, its my prototype. I can make it as big or small as I want. For proof of concept, a great place to start, would be just getting it to hover. Alright, I see what you guys are getting at. I'm so sorry. I didnt mean to take up forum space, and thread, but thank you. I think I know where...

    Airfoil Size calculation?

    I agree, where would you start? and why? What are the things you need to know? Yes this is a requirement. I need the vertical take off and hover. What do you mean by effective area? I said 20 mins, in my opinion, that is pretty reasonable for an experimental drone. I can learn. I've been...

    Airfoil Size calculation?

    Whats the best way to figure out how big my airfoils need to be with these knowns. Goals: Lift 4.5kgs 1.5meters in the air for 1200secs (20mins) And since im designing a cyclorotor with 4 airfoils within each prop. There is a total of 16 airfoil blades. How should I approach this? thanks...

    3D Printing Gears and Carbon Fiber

    I was gonna get some pieces, made from emachineshop.com. And there are some options on 3D hubs as well.

    3D Printing Gears and Carbon Fiber

    Interesting! Well, to answer your question. Cores. But, since you guys laid it out like that. I'm thinking I can find another way. Seems reasonable to have the teeth and hub machined, and then fixed into the composite webbing. I can still design what I need, the way I go about it might have to...

    Oh, ok. Well ****. Thanks Bob K, I was having some trouble understanding that article fully. I appreciate you schooling me sir. Would using an Electric motor change the outcome of things?

    3D Printing Gears and Carbon Fiber

    I will have to post my results then. http://technology.nasa.gov/patent/LEW-TOPS-41 This is also pretty cool. I sent an email requiring, not too sure how that all works. But, I'd love to find out.

    3D Printing Gears and Carbon Fiber

    Anyone give that a shot? I'm going with a belt driven pulley system, and I've been designing it in CAD, polishing up my skills to get it print worthy. Also read some pretty interesting threads on here, and some of yalls experiences with vacuum bagging motivated me to learn. So just waiting on...
