Thanks for providing that. So the 350R has a longer Chord, but there outer 7" isnt contributing much because it curves down to attach to the trunk, while the 1LE wing is not only wider, but all of the width contributes to downforce, making for a far larger effective area and span.
I don’t think you’ve actually seen this wing before in real life, or versed in how aero works. It curves downwards at the leading edge, but the trailing edge still curves upwards dramatically. This means there still a very low pressure region below its surface. This is how downforce happens. The extra 7” you deem ineffective produces most of the wing’s downforce due to its exposure to a cleaner laminar flow and a more aggressive AoA.
Re-read what I said. The outer 7" (of the span) that curves down and attaches to the trunk (like a Nissan GTR) rather than a proper straight wing like a ACR, GT3, or 1LE.
I'm fully aware of all that. Doesn't change my assessment.
You seem to be making up your own numbers, even though you have no access to the data. Here is a cross section of the "outter 7'" you invented and somehow deem to be ineffective, it is still an airfoil and still has an AoA. The wing's section that is aero neutral is only 5.02", not 7, so your math is wrong. 50.8x9.44 = 479.3 sq-in.
The one your friend has is probably an aftermarket knockoff, not the real thing or scaled 1:1 to a 350R’s spec. I have not only seen the real ones, I’ve built them. I also build the 1LE’s wings, it’s not like I have cad data just lying around for no good reason. The only part of the R’s wing that is aero neutral(Isn’t an airfoil) is only 5 inches, not 7. I made that clear previously with pictures.
Have YOU seen an R wing in person? My friend has one and I can assure you that the 5" you have outlined is not the shape of an airfoil (perpendicular to it's chord) and thus does not contribute to downforce. -unless you can provide a crossection in the middle of that 5" that's cut perpendicular to it's chord (~45*)??
If you actually read what I type instead of selectively reading what you disagree with (the problem with society today and why we can't have useful debates that move forward in any beneficial way) you would realize that I would possibly give back half of that 5" back if you could provide a cross section of the middle of that 5" perpendicular to its chord, to see if it we're truly an airfoil :frusty:
The area right next to the highlighted region is also an airfoil, I posted this picture previously. There is a reason I told you that only the highlighted region in red is aero neutral. The highlighted region is 5”, not 7.
Correct me if I'm wrong but it looks like the cut is made at a 90* angle, which is why I asked you to cut it perpendicular to the chord (~45*) in the MIDDLE of that 5" upright.
The cut isn’t made at any angle. The position you see the wing is the position it sits on the trunk of the car. It is angled by design. You asked me to correct you if you are wrong, and I have.
I really hope you're not an engineer that makes parts :frusty::frusty::frusty:
No one is debating wether the 5” area creates downforce or not, I already told you like 5 times already that it does not. You seem to lack reading comprehension yourself.
