|3D modeler needed for open-source RC combat glider [message #114648] Tue, 28 April 2015 01:26 UTC
I participate in this crazy fun sport of radio-controlled glider combat. These are 4-foot flying wings built around EPP foam cores, stiffened with carbon spars and tough-flexible skins. We dogfight these planes in ridge lift with everyone trying to put everyone else down. Collisions are often brutal and normally there is no damage. Here are the plans for the foam version. Be sure to watch the video near the end to see it in action.|
These planes are annoying to build and maintain, and clearly 3D printing is the future of this sport. This should make them even faster and tougher and almost trivial to assemble. Someone needs to get this going so I'm willing to pay a modeler to create the first version which I will share with the world with the hope of attracting more people to the sport and finding others who will help to improve the design. I realize they will also cost a small fortune to print today but certainly prices will quickly fall, so I am prepared to incur these development costs as well.
This being a labor of love, I can't pay like a for-profit business can but I do want to pay enough to keep the designer happy. Of course it will help if you have an interest in flying and knowledge of the terms and trade offs involved in aircraft design. I strongly prefer someone in San Francisco or the SF Bay Area, or possibly a remote designer with the ability to screen-share and work closely together.
The specifications are nearly complete so it should be fairly straightforward. The one exception is the modelling of the skin which is also the main structural component. The complexity comes from the fact that the skin thickness must be heavy towards the front and thin towards the back in order to keep it from being tail-heavy. I've designed the inner and outer curves for both the root and tips of the wing. You will need to be able to extrude these inner and outer curves to produce the inner and outer surfaces of the skin which should produce the appropriate thicknesses at each point. If you can do this, you can probably handle modeling the component bays and other needed details.
There will also be opportunity for you to show off your ability to model beautiful compound curves. That is not a requirement for the first version but I am willing to pay you for those beautifying touches if that interests you. This is not a one-off project, so I am keen to find designers who know how to model in ways that others can most easily pick up and modify.
I have attached the skin curves in Adobe Illustrator format along with a rough overview diagram. Please let me know if you are interested. You can email me directly to firstname.lastname@example.org. Thank you.
