Spitfire F.IX - speed and climb

[Pyro]

RAM, you sure are a conspiracy theorist.  BTW, what's the conspiracy behind the C-47 not having stats up there?

NII-VVS tests (18 november 1944) of Spitfire LFIX (serial number 15667)

Max speed km/h:
0m alt = 515(549 with wep)
1000m = 536(570)
2000m = 544(578)
2400m = 556(577)
3260m = 559(596)
3600m = 563(581)
4000m = 580(618)
5000m = 590(628)
5500m = 601(627)
6000m = 614(624)
7000m = 611(622)
8000m = 611(613)
9000m = 601(-)
9500m = 595(-)

Climb ability at alt, m/sec:

0m alt = 19,6(22,8 with wep)
1000m = 19,6(22,8)
2000m = 19,6(22,4)
3000m = 19,6(20,5)
4000m = 17,7(18,8)
5000m = 17,6(18,6)
6000m = 17,2(-)
7000m = 14,6(-)
8000m = 12,0(-)
9000m = 9,4(-)
10600m = 6,8 (-)
12800m = 0,5(-)

Time of sustained turn at 1000m alt, sec:
17,5
Turn radius m:
235

Nice Aper!

Thanks!

[funked]

BTW That is a 3.2g sustained turn.

Aper may I ask what is your source?  Do you have the actual NII documents or a book which quotes them?  This type of information (especially turn rate and radius) would probably be very useful for HTC!

The Spitfire data I wrote above were taken from the book "Spitfire" which was issued in Russia. There is a special chapter about  the Spitfire-LFIX tests in NII-VVS.

The original NII-VVS sources I have are only about captured LW planes tested in Russia in 1942-44.

Your tests.  Your comparing our WEP to their MIL.

pyro can you post graphs for the AH spitIX F

just so I know what altitudes I have more power to work with than the spit in AH

   Aper, do you have any hard data on any of the Italian aircraft used in the "Eastern Front"?
   It is a bit hard to find numbers rather than "light and balanced controls...".

Citabria, the "worst" performance for the F.IX would be at around 18,000ft, +/- 2000ft or so.

Sorry, there are no hard data on Italian planes from NII-VVS. Actually FIAT CR-32 (that was captured in Spain as well as He-51 and Bf-109b) was tested but I didn't find the FIAT's hard data such as speed/climb charts etc. But the time of sustained turns are:
FIAT CR-32 - 13,5 sec
He-51  - 11,3 sec
Bf-109B - 16 sec (without flaps)

Huh?!?!?! A He-51 outturning a CR32?...

Well I used to think that the italian CR32 biplanes were the most maneouverable birds over Spanish skies!...

*crackle hisss*...CR.32: 84.4kg/m^2, He 51:69.7kg/m^2...*fizz pop*
