# How to actually draw a wing properly

I’ve been trying to draw a wing with data such as

Ctip, Croot, b, lambda (Taper ratio) and S

What I’m struggling with is how to actually start with this if we don’t know the angle created by the fuselage with the as trailing or leading edge shown in my picture

So when we first draw the Croot and a Ctip a distance away from each other, how far to the left or right would I draw Ctip?

• What is lambda in this particular case? Leading edge sweep, 25% chord sweep or what? Mar 29, 2022 at 9:03
• Is that diagram intended to represent a wing? Mar 29, 2022 at 15:11
• @MichaelHall Yes, that is how you graphically determine the mean aerodynamic chord. See this for an explanation. Mar 29, 2022 at 15:54
• @PeterKämpf, thank you. Your diagram is MUCH better, and I see a wing now. All I saw this morning was a messed up looking Roman numeral twelve... Mar 30, 2022 at 0:19

$$C_{tip}$$ is at a distance of ½b away from $$C_{root}$$. Placement left or right in the drawing follows from the quarter chord sweep angle.
