Operating Flight Strength

A bit of Aerodynamics here from AviationChief.com

This shows how we construct V-n and V-g diagrams. It does NOT show how to construct a g-available chart, but will give an idea of aircraft manual charts of the type covered are constructed.

P.S.
I wanted to attach a .docx file, but it is apparently not allowed. To the administrators, please think about allowing a .docx since anything that can affect a .docx file can affect a .docx file, too.

Here's another Word file on aerodynamics from the web. Not for the casual WWII aircraft fan, but semi-decent if you are interested in the subject.

Are you kidding me Greg? I can barely make it through one of Bill's treatises excellent though they may be! LOL

If you use Microsoft Excel, the equations are easy.

The thing is, this is just the operating strength. What is missing and may NEVER be revealed is the g-available curve for WWII fighter, which tells us how many g's at what altitude and speed can a WWII fighter sustain. The thing is, g-available curves weren't necessarily know during WWII, so it unlikely they will be uncovered, and I'm not too sure anyone except an aeronautical engineer could generate one with an accuracy.

Bill Marshall might be able to generate one, but I am not well versed enough to do it. The last time I looked at theoretical aerodynamics in any detail was at college in the early 1970's. Sure, I can do things like stall speed at different weights and bank angles in level flight, Changes in speed from some theoretical change in power, turn rates, turn radii, etc, but I don't believe I ever saw any calculations for g-available even when I was in aerodynamics in 1971.

I'd be happy to contribute the Microsoft Excel if Bill or another aeronautical engineer wants to share the calculations, though. I pretty sure we'd have to know the airfoil (and so CL and CL Max, including with slats and/or maneuvering flaps), MAC, and a few other things that I don't have for most WWII fighters, though.

Hey soulezoo, send me your email address in PM and I'll send you a couple of possibly interesting files.

Cheers!
