T-34 Aerodynamic Questions

[fighterpfeif]

Doing a project in my applied aerodynamics class where are supposed to "take apart" or "aerodynamically describe" an aircraft of our choosing.

Chose the T-34C and got a hold of the old NATOPS offline, but running into some problems. I can't find certain numbers. The first being the wing loading or the wing area of the T-34C. Any help?

I could be wrong but I think that maybe the maint. pubs would be a better source for this type of information...hope you find what you are looking for though.

I could be wrong

Go with that. Maint. pubs are very basic and contain little to no engineering data. These guys aren't building airplanes, they're mostly just removing and replacing components. I'd try to get stuff like that from the A/C manufacturer.

Just did I quick search on google and this time found the wing area.

Do the maint. pub have NACA numbers and where can I get one for the T-34C.

(If anyone knows that NACA number for the T-34C that will work)

If you know s, can't you just look in the NATOPS to find w?

Thanks for the correction, like I said figured I might be wrong but that was what came to mind first off. I have seen some who use the maint. pubs to get exact numbers but using extra information there and doing a little math, such as the speed of each gear in the transmission of a TH-57.

A/C manufacturer would clearly be a better source for this type of information.

No joy on the NACA num. in the paper Natops either...sorry.

You really think the T-34C uses a NACA airfoil?

I would guess that they would use one that is a little more specialized. I could be wrong though.

EDIT: Found out that I was wrong!

Found some of it:
Cantilever low-wing monoplane. Wing section NACA 23016.5 (modified) at root, NACA 23012 at tip. Dihedral 7°. Incidence 4° at root, 1° at tip. No sweepback. Fixed-incidence tailplane.

Anything else while I am working on it?

In finding the NACA number did you by chance come across the length of the chord. Also where did you get the information for the NACA # and the wing design from?

Actually, the F-22 even uses a NACA series airfoil. A 6, to be exact. You would think they would make their own for such a crazy-high tech plane....but apparently not.

Much appreciated PU Grad. That helps to fill in the blanks
