Wing Design

[GregP]

Some folks in here have asked several times about wing design.

Attached is a chapter on wing design so you can read it and get your feet wet. It isn't exactly the last word on the subject, but is a pretty good starting place for budding wing designers.

No paricular reason, just interesting, at least to me.

Enjoy.

I have Hoerner's lift and drag files, but they are 66 and 35 Mb respectively, so I can't load them. If anyone really wants a copy, PM me and we can work it out. I can't email it but can send a CD/DVD if you will work it out with me.

That is excellent, thanks!

Interesting, I can now see the obvious flaws in the F-35 lol


seriously Greg it was a good read, thanks.

Interesting read. The rest of the chapters sound intriguing too. Are they available anywhere?

 

[GregP]

I think so. I found this one by Googling "Wing Design pdf" and I daresay you could google the book title with the pdf add-on and find it.

Actually, I have a lot of great pdf's but never really thought of starting a thread dedicated to aviation-related pdf files until now. When I get done with this next class I'm teaching, I'll start that thread. Maybe a few samples now.

Thanks, I found it. It's one of a several extracts from "Aircraft Design: A Systems Engineering Approach" by Mohammed Sadraey at Daniel Webster College. The book itself is a couple of hundred dollars, but there are enough extracts at Daniel Webster College - Mohammad Sadraey to be useful. The available chapters cover:

- Conceptual design
- Preliminary design
- Wing
- Tail
- Landing gear
- Control surfaces (separately ailerons, elevators, rudder, spoilers)

There's also an interesting chapter on drag and drag coefficients from another book "Aircraft Performance Analysis".

Thanks for that. I was onlt thinking of giving some folks who had asked about wings in some threads a place to start, but looking at the rest of the text that is available will be fun.

These might also be of interest:

NACA 4 digit airfoil generator (NACA 2412 AIRFOIL)

NACA 5 digit airfoil generator (NACA24012 AIRFOIL)

Thanks! Again ...

Is there a place on this forum to upload such files?

 

[GregP]

I haven't located it if there is.

Also found these:

REPUBLIC S-3 AIRFOIL (s3-il)

P-51D ROOT (BL17.5) AIRFOIL (p51droot-il)

P-51D TIP (BL215) AIRFOIL (p51dtip-il)

Haven't seen figures for the S-3 airfoil before, or thickness figures for the P-47 (granted, no details on whether that's root or tip). The leading edge of the wing looks very similar to a 230 X X series NACA airfoil, but the trailing edge goes concave making more of a teardrop shape.

Again, thank you!

Interesting. What's covered in that paper is essentially what aircraft maintenance engineers are taught as part of their exam syllabi. Take a look here at the FAA website for pdfs on Airframe and Powerplant Mechanics Airframe book.

AC 65-15A - [Large AC] Airframe and Powerplant Mechanics Airframe Handbook â€" Document Information

Here's the Powerplant book.

Here's the Jeppesen airframe book.

These aren't pdfs though, sorry.
