Nice data! Any more like it? Where did it come from?

Thanks.

Cheesus! That is one hell of a piece of data! I haven't seen any roll rate information never ever on any book or in net!

From where did you got this?

Ok, lets look at the data...

Fw 190 rules as excepected, so it does in AH.

Spitfire seems to lock up aileron badly on high speeds, something that I havent find true on AH unless it has been changed recently.

Clipped wing Spitfire would be verrrry nice addition!

Someone has some testing to do...

Someone sent me this picture, but look at the footnote, it´s from an NACA report and you can even download it. It has 76 pages, too much for my modem connect  , but you can find it here

Holy toejame, that link is very important and useful!

I thought P-47 would roll better, almost like Fw 190 but seems like that is not the case.

Whole report is only 6.6 megs, all 76 pages. I'm gonna e-mail the link to Pyro or HT and see what they can do with it.

Most curves have a special point where the curve begins to decrease. Note, all curves are for 50 pound stickforce. That means left from this point, at slower speeds, the rollrate is for maximum deflection of the aillerons. The stickforce which is necessary for full deflection is lower than 50pounds. At this special point the stick forces reaches 50pounds. And for higher speeds, 50 pounds don´t allow anymore full deflection, and roll rate dereases.

That´s my interpretation

Hey, people who think that the Spit shouldn't roll at high speeds, heres an update for ya: we don't have a Spit I or II that had FABRIC ailerons. We have Spitfires of higher Marks that had METAL ailerons, which was fitted to Spitfires in late '40, which drastically increased reponse in the roll axis at high speeds.

Niklas your interpretation is correct.

Nath I'm pretty sure the clipped wing planes all had metal ailerons.  Not sure if the "normal wing" data is for metal or cloth ailerons.  I'd guess the latter.

Just had a look at the full text of the report.  It's got transient data woohoo!  

It's also got information on wing twist (Pg 131) and aileron skin deformation (Pg 174).

Cool stuff.
