Summary

Here's my take on a wing. I modified the previous wing design to be a solid model of the wing. My theory was that skeinforge handles generating both the outline and the 'struts' (infill) very well. I printed a few wings off, and they look really good. Not sure if they will work or not though.

Instructions

Print and attach to fuselage.

hi any chance you could share the cad files as i want to make some canards for a little delta but would like to do a few mods to them the ones i printed are good but want to change the part were the wing would mount to the body to add a bit more sweep and make the trailing edge go flat to the print bed plus put a hole for a carbon rod
thanks dan

If I can quibble on the aerodynamics of that wingplan, I think the taper is a tad excessive... I realize it helps the wings to not fall over during printing, but isn't the base fused to the printing surface?

This one's really my fault-- I designed this wing to look like a scaled down plane wing, but that's not at all what you want for actual fliers!

The model aircraft I see in the shops all have virtually no taper, because at the speeds they operate there's no need for it, so all it accomplishes is reducing the size of the available air foil!

The best flier wing would probably be made by extruding the wing profile more or less straight up and then gluing multiple profiles together to make a full sized wing... Actually brb with that model...

You know... at low speeds (low weight) the airfoil shape hardly matters and a thin plank might be enough. Wonder if we could design a model that prints in one pass, fits in a 10x10x10cm cube and glides decently well right from the start.

Based on past experience, it might be easier to print a canard on its tail, easier to place the CoG and easier to balance during printing.

I think it might be doable if the weight can be kept low enough.

We'd be talking about something smaller than a paper airplane at that point...

Unless...

Suppose we printed half the aircraft on its side, at a diagonal, then the other half. You'd get a maximum wingspan of 20cm and a maximum fuselage length of 14cm...

You'd take a weight penalty managing the join, tho.

There are radio controlled gliders in this size range. Their structure is much lighter than what we're considering here, but they have an electronics payload along for the ride.

Ah, right-- letting Skeinforge print the wing as a single-strand wall is probably the lightest it could possibly be.

I think this could probably be printed with no internal supports at all...

I didn't know it could do that! That's awesome. :-)

Any chance we could see what the infill looks like?

How much do these weight?
