Design Help: Wing Top / Fuselage.
I’m always having problems designing the joint from the wing top to the body.
This part of the wing bend bends in an arc from front to rear and also bends up from wing to body. When I model it in Rhino it always looks fine but doesn't unfold as it’s bending in two directions. The only way I seem to get round this is to cut the area in small flat parts and unfold them separately but means a lot of small parts, not good when modelling in 1/72 scale. I would be appreciate any advice in modelling this part of a plane. Cheers JTF |

My solution is to extract isocurves from surface, cut along isocurves, and unroll each part separately - and then silhouette/trim/join.
See attached file. It's not perfect, but works. EDIT: when unrolling, use "labels" option to not mismatch the edges.

If you model it in Rhino, use the Fuselage as a cutting tool, using the "Split by Isocurve command", looks like a little rectangle with a blue triangle cutting into it. Do this before you unroll any of the surfaces. Make sure the wing is right where you want it, then cut. It will fit perfectly that way. It will ask you "Select Object to Split" Select the wing, then press "Enter", then it will ask you to select the Cutting tool" Select the Fuselage", then press Enter. You will have to delete the little piece of wing that gets cut off to get it out of the way.

STRK, you make me laugh, man you're fast!! @ JT Fox, you just got some really good advice! There are lots of ways to do things in Rhino and get the same results.

I spent many hours trying to successfully design, unroll and glue that element (it's an exhaust deflector from pr. 903 strike ekranoplan Lun).
I asked some guy(also working in paper and Rhino, he's known in Poland for very detailed and sophisticated paper WWII planes) to help me out but the only answer was: No-one has ever helped me, when I was designing my models. So I'm not going to help You. Isn't it pathetic? That is why I try to help as much as I can.

I have run into that too. Especially when I was a machinist or programming CNC machines. It is pathetic. I think that is one of the things that make this forum great. People freely help each other. Some of this info you would have to dig really deep for.

I made it my mission to share as much airbrushing skills as possible (over the last 20 years) back to the Wing Fairing.... I have one question: which is more difficult, designing the wing root fairings or (as a modeller) installing them?! lol Most modellers would probably claim the latter, because we are mostly builders, not designers. I understand with smaller scale models, you want fewer parts and so the tendency is to design a simplified version of a part like this, (I'm doing that right now with my Hercules fairings) and then rely on the builder to contort it into shape. But really, the best approach would be to copy the real thing and make it in sections. Take a look at the Spit fairing...its in four parts. Wouldn't this also make the design stage a little easier too?

Yup, I think there is a tendency to forget how the real thing is made. People go to great extremes to make body panel lines but forget those lines are there because they are edges of separate parts.

Thanks for the great advice.
I'll give it a try and let you know how it works out. Cheers JTF |
