Performance of the Fw 190A on the Deck?

[Crumpp]

This flying at constant AoA would, I think, be relevant to cruise, where a heavier aircraft does indeed require a higher speed.

Graham I think it certainly has been quite a while since you worked with aerodynamics. From what I understand, it is like riding a bike and it comes back.

You missed the point on the parametric study. The only way to judge the affects of weight is to hold a constant, adjust weight, and measure the results. Otherwise we miss the forest for the trees.

That is the basic scientific method and is generally accepted for aerodynamics and applied physics.

Not doing it leads to false conclusions on the relationships. We wind up with statements like the affect of weight is insignificant because we only see a small reduction in speed.

Here is another reference on this subject:




Now I understand you only wanted to make the point that "in regards to top level speed" in a very narrow definition, the affect of weight is insignificant.

I guess you could make that statement. I certainly would not make it. Once again it sounds to me like a Doctor claiming the small size of a cancer tumor means it is insignificant to the body.

On the other hand you might like try being polite, even when you disagree with what others have said.

Hi Nick,

Point taken. And you are correct. Thanks.

All the best,

Crumpp
