Airfoil Modelling Tutorial

This is an Extension of EternalDarkness' Fuselage Slicing Wing Technique Guide.

Unlike in EternalDarkness' guide where the wing tip of the wing is on a fixed size as the wing root. This one features a difference in size on the root and tip of the wings, much like what aircraft wings are done.

This intruction is already in the Craft Constructions, but ill leave it here aswell.

I recommend examining the Blue one first as its alot easier to understand the method.

Color Code:

Blue: 100 : 50(+0%) by 50(-0%)
Orange: 100 : 62.5(+25%) by 37.5(-25%)
Red: 100 : 67.5(+35%) by 32.5(-35%)
Black:. 100 : 72.5(+45%) by 27.5(-45%)

Do note the result should always be upper+lower is equal to Front
Example: 67.5 + 32.5 = 100

Calculation:

A = Front Fuselage height thickness
B = Back Fuselage height thickness
C = X%
Solutions:

1). Upper Fuselage:

B = ( A x 2) + C

Example:

B = (0.3 x 2) +25%
B = 0.6 +25%
B = 0.75
height thickness

2). Lower Fuselage:

B = (A x 2) - C

Example:

B = (0.3 x 2) -25%
B = 0.6 - 25%
B = 0.45
height thickness

    Did i just discovered basic NACA Airfoils in SP?

    is there a way to account for rise and run or is it all the same

    @SAT0rii ive been using the wing modelling for over q year now, and it wasnt until recently that i figured out the way to calculate it.

    Was looking for a tutorial about this for the longest time. Great work man.

    @Grob0s0VBRa ah, the wing thickness. Yeah indeed it is. It can be the same on thr opposite where it thickens up too.

    @KingOfTypos nope.
    You can still use the same technique as you did, but front fuselage can have different fill (not only 0.5).
    So, it goes for all the fuselage pieces you make wings from, not just wingtips

    @Grob0s0VBRa by mean "fuselage with circular corners", did you meant the wingtips?

    Magic numbers for fuselage with circular corners are:
    0.017
    0.067
    0.1464
    0.25
    0.3705
    0.5
    and they just mirrors further (make 1 - number calculation)


    Use them in top, left, right, bottom fill.


    Experiment.

    @Vincent could you make this a successor to this post?
