I wish I had it sorted I'll make the rear wing first since it's smaller and I can use fewer materials until I get it right. Right now the front wing is 650, and the stab is 180. Right now the longitudinal stability report says it's stable, see below. I read somewhere that the area of the stab was 1/3 of the front wing. I wish I could understand this software a bit better.plummet wrote:Cool looks like you have it sorted. my research suggests you may want around a 600cm2 surface area. Rear stab 60% the dimensions of front wing.
Are only 2 layers enough? I was planning for 3 at least. Any opinions on using Kevlar (or even S-glass?)Vac bag a couple of layers of carbon over top of your 3d printed wing shapes and it will be sweet.
Indeed that's the plan. Problem is that unfortunately, the printer is too small to print the entire front wing at once. In fact, I have to print it in 5 sections. Each section takes about 6h to print. But you're right, it's cheap to print.If you have 3d printing capability why not print and try several designs?
Thanks. I'll do some research on PE resins.tkettlepoint wrote:unless you use polyester resin. there might be a bonding problem also on PLA. I know I have fixed a lot of surfboards and tried epoxy over the polyester board is it just a pain in the butt
I can definitely do that, not hard to implement into the design.Bigdog wrote:If you printed little holes in the wing to act as keys for the epoxy it would hold I think.
Thanks. Do you have any images for me to see how this looks? Might be one option also.Blackrat wrote:if your carbon layup is sufficient then it doesnt matter if it delams , all my wings are hollow with an 'I' beam shearweb to join the skins
