horizontal building combs

[aliraminghe]

I have assembled a leprechaun kit with lasered horizontal LE and TE on elliptical wing, those are a great help as they can be the final LE and TE too, further that way you don't need a plan to build because the ribs are automaticalyspaced and kept square. What about adding this feature for the next version

Hello Carlo,

Sorry for the ridiculously late reply!

I am not quite sure what exactly you mean by that, but I'll give it a try: if you mean a kind of a bent LE with notches in the ribs to fit, that would be a very hard and error-prone task to automatize. I have received in the past requests for the horizontal comb, but I never found the courage to give it a try.

I'm rather conservative when I sense the danger to produce much "throw-away wood" for the Wing Helper users.

I might get around to do it one day, but for now, it's not high on the priority list.


Cheers, alex.

I think he is referring to using flat stock for the trailing edges on the bottom of the rib, but with a curve for the elliptical layout. I'm not sure your software currently offers this?

Here is a wing we did in Wing Helper, think we had to do the trailing edge in CAD:

Ignore the mismatched plane, it is just for flight testing the wing.

That could be, but he is mentioning a comb in the subject, so if he had the same type of comb in mind as Wing Helper offers it vertically, that would not be easy.

In general, everything bent is just an approximation, and when you have approximations in the code, the errors are accumulating. If in the end, there is a 2mm error in a 1.5m wing, that's an absolute no-go.

Oh, BTW - that's a BEAUTIFUL wing!
