WWII aircraft perfomances

[regula50]

Hi:

 

A very good site with a lot of data and informations about perfomances of many aircrafts of WWII.

No a new one this site, but always updated with new informations and historic documentation. 

Good reading!

This article for example is a classic of this site:

GREAT site!!

It's a great site with lot's of info but comparisons are often...well...they can be misguiding.

They either compare older German plane types with newer Allied or use testing of crash landed German planes and then compare them with pristine condition sealed and polished allied planes at experimental engine boosts etc.

 

This comparison on the second link is exactly one such example.

It shows in speed graphs only E-1 and 1938 E test, while dominant variants in BoB were E-3 and E-4

Here is an example for a test of the BF-109E3: http://kurfurst.org/Performance_tests/109E_Baubeschreibung/109E3_Baubeschreibung.html

As you will be able to see in this test the E-3 hits 565kmh at altitude, that's 352MPH not 342MPH. Also engine limitations in the link are false which is nothing new as previously that site even had comparisons of german planes at combat power vs. allied on emergency power which ofcourse is not the same, as for this example max engine speeds for DB601A and DB601N were 2600RPM and 2800RPM respectively not 2400RPM as on the site which cites prewar BF-109E data and then compares them with wartime Spits...WTF?

All in all, a very cool and detailed library but comparisons suck and tests of allied planes are mint condition that was never or rarely met on the battlefield...(like I said, polished, lightened, fully sealed(guns too!) etc)...

Yes, the engine limitations era always a polemic or discutable theme.

6 or 12 boost,wich type of octane, how many a.ta, wear or new engine, so many factors.

About the E-1 there where still a good number in service by the Battle of Britan. After losses by Aug 1940, of 100 Bf 109 losses: 40 were E-1, 8 were E-3 and 52 were E-4s.

As late August there still E-1 in combat armed only with four MG 17s and by January 1941, the JG 2 had always a good number in front line service. Certainly about this time most of the E-1s were modified mainly as Jabo.
