109 Flaps

"As noted several times in this thread; the RAE used several different metering devices and instrumentation for those high speed test dives (as an example rakes to measure pressure distribution). IIRC Morgan&Shackladys book contains some illustration on these devices. They tried to continously improve the methods and also corrected results afterwards once the better corrections became available."

TY, that is what I was wondering.  Is it documented what kind of metering system was used in Spitfire's high speed tests?

If you mean those tests where mach 0,89 was claimed with a Spitfire XI, there is IIRC pictures in the report (I have only seen the report couple years ago in the PRO). Basicly a pitot tube but specially made for these tests, in addition there were devices to measure temperature etc.

Here's an odd question.
CL is based on the airfoil right? The amount of lift created with the airfoil?
If it's right, I have an odd point to add.....

Yes and no.

The airfoil shape of course affects on lift characters of the wing and the limits of the Cl. But the Cl itself is just a number to handle lift of the wing in analyses without physical dimensions of the wing.

Are there any error correction tables available for Spit as are available for FW?

It would be interesting to compare them to see how much pitot system location affected the results.

Charge,
There is at least one in the NACA test report, note that it's not same system as used for the dive testing.

I haven't followed this thread for quite a while (since page 3 or so) so just in for a quick question as I am too lazy to search through 6 pages.

Was there ever any conclusion to why the 109 flaps were "overlooked" last version? Any replies from HTC? Any (frustration mode moved up a notch) why da hell has there not been a quick fix in a patch to this as it was "overlooked".

Will it be "overlooked" more times before CT?

the AvA is a good example as to why HTC must turn a blind eye to the whole LW modelling thing the allies are being trounced even with the nerfed LW planes.  imagine what it would be like with anything closely matching what the planes flew like as reported by FW and Messerschmitt the game would be void of players.

or you are, in fact, proving that they are correct in their modelling by proving they can be competitive when flown historically.

What other planes have their flaps overlooked? They all should be fixed at the same time. Too bad that fixing only a few planes looks like an artificial crutch to boost those machines.

"or you are, in fact, proving that they are correct in their modelling by proving they can be competitive when flown historically."

The 109s and 190s can be flown competitively in AvA but that hardly is sufficient to tell about their correct modelling.

It surely was an eyeopener to try SpitIX on AvA last week... :lol
Not so much better than 109 in turning as I thought, but with that aileron speed and cannons it is very dangerous in reversals except that I doubt single Hisso round can take off a wing of a 109 from 600y distance or that Spit was that good in rolling plane especially with speed, not to mention the lack of accelerated stalls in rapid pull-outs...bla bla...:p

109 has its high speed elevator forces nicely modelled so why are the heavy ailerons not modelled in Spits?

oh come now, surely you are aware that slightly modified hisso knock offs were utilized by the soviet union to shoot down gary powers in his U2.  that whole cockamamie SA missle story was a cover up to hide the true weapons system. and it was a single ping too.  honestly you luftwhiners are really overbearing.
