Dear friends,

In exchange for a copy of these documents I promised to scan them and publish them online. Quite a number of interesting PRO documents on various subjects.

Ruy,
I took a look at the site, and as far as I know you should have no problem with posting this material. But might I suggest that you include the PRO document
reference (Air x/xxx) so that other people can look for similar material in that area at the PRO.

Frank.

Thanks Frank,

The problem with the AR #s is that some are very hard to read or incomplete. Will add those that I have when I have some time.

Dear Ruy,

Thanks for sharing these with us. The documents I have from 1974 say something about copyrights on PRO records. Has this changed?

From a scanning technical viewpoint, I'm curious as to the dpi these were scanned at and whether scanned as photos, which I suspect, or as printed documents. By
the quality, they look like 600 dpi photo scans, which would consume a lot of memory. If there has been found a much lower memory method for scanning historical
documents, I'm all ears.

Warmest regards,
Richard

Scanning docs

depending on the quality of the document and its' tonal range, modern scanning software, such as Vistascan will allow OCR scanning which produces a B&W
document of high contrast (similar to a fax) at 300dpi. I am regularly scanning text documents and producing Adobe Acrobat files in this fashion. For example, a one
page text document can produce an Adobe PDF file size as small as 30 KB.

Note however, if the original document as mid-tones, such a procedure will not work as OCR reproduces as blacks and whites only.

Regards

Rod

This information is simply not available in a concise manner on the web. Maybe you can find some sites claiming to have such data (mostly from graphs taken from
Air Warrior, the multi-player sim), but IMHO this is not authoritive and even questionable.

I've seen some Rechlin reports and Allied reports, but to get a picture as you are asking is nearly impossible without thorough research by yourself, it is that simple.

As for aerodynamic basics.

The 109 must be seen as two a/c.

The early models B up to the E and the later models starting with the F up to the K. For both early as with the late models the basic shape stays the same, thus we
are left with changes in weight, drag, horsepower, wing loading (and sometimes CG). This makes the overall handling something we can deduct.

These questions are most often asked by people who want to do something with combat flight sims, and they need data like roll rate, speed at alt graphs, climb rate
graphs etc, all this for each sub variant so they can either claim it is too good or not good enough.

But even in a book like America's Hundred Thousand, where the author had much more to work from then we have for the Luftwaffe fighters, there isn't always this
exact data for each and every cicumstance and sub-variant.

For the Emil, there are two RAF reports I have online on:

You might take a look at these.

In the end you need alot of time and a lot of reports, books etc to make your own puzzle. I doubt that anyone can give you the answers outright, if they could you'd
have been able to buy the definitive 109 book a long time ago...I'm sorry.
