IL-2 Compare with Great Battles airplanes data for top speeds

Recommended Posts

Posted (edited)

Here is data from my top speed test on Il-2 Great Battle airplanes for original Il-2 1946 compare program. 

 

Original IL2 Compare was created by ROSS Youss ( as far as i know ), and you need to have that program first, you can get it from this link:
http://www.mission4today.com/index.php?name=Downloads&file=details&id=329

 

Here is link for my test data files ( DataCraft, DataSpeed and DataTurn, size 35.63KB ) :
http://www.mediafire.com/file/sn9a20qiugoumau/Il-2BoXtestrdat_v3.zip/file


First download original IL-2 Compare program from Mission 4 Today link (if you already dont have it with your old Il-2 1946 game ), instal it, delete or rename original DataCraft, DataSpeed and DataTurn foders containing Il-2 1946 airplane data. 
Then download my test data files for IL-2 GB "Il-2BoXtestrdatav3.zip". Extract it and place its DataCraft, DataSpeed and DataTurn folders inside original "Il-2 Compare" folder.
And then when you double click on that "il2c.exe" inside "IL2 Compare" folder, you should only have listed airplanes from Il-2 GB game when program starts, and their data.

If all was done correctly it should look like this:

Data for Il-2 GB is manualy edited (its not generated by FM extractor mod like it was for original il-2 1946 version from my understanding, i dont know if that mode for Il-2 1946 still exist, and if it would even work with Il-2 Great Battle game).


I use this for refreance for how airplanes in this game relate to each other in top speed, if you see something strange or wrong its probably because of my mistakes in tests or IAS to TAS conversion, test it your self and you can easy edit files with your test data to what you get as correct numbers. 
Chart data for MAX TAS by Altitude is taken on Kuban Autumn map (no wind, no clouds), same for all tested airplanes. Mostly at 1000m intervals ( for some airplanes also 500m or less intervls ) 
IAS is taken from game HUD when auto level is turned on, and airplane is spawned in air in QM at desired alt, flying strait on set power for 5-10min depending on alowed power setting. 
TAS neccesary for speed chart is then calculated with this: https://aerotoolbox.net/airspeed-conversions/  ,( IAS from game is placed in "Equivalent Airspeed:" field )

 

Airplanes engine power, and condition:
Bf-109s = first line is combat, 2nd line is emergency. (on 109G2 2nd line is manual rpm up to 2800 for 1-2min) , (Default loudout, with 50% fuel).
Fw-190s = first line is combat, 2nd line is emergency (A8boost = boost on, A5U17 = boost on, no bombs ). (default, 50%) 
Bf-110s = first line is combat, 2nd line is emergency. (default, 50%) 
Me-262A = first line is continuous, 2nd line is emergency. (default, 50%) 
Ju88 = first line is combat (Climb power), 2nd line is emergancy (Take off power). (default without bombs, 50%), (no overheat conditions)
He-111s = first line is combat (Climb power), 2nd line is emergancy (Take off power). (default without bombs, 50%), (no overheat conditions)
Ju87 = first line is combat (Climb power), 2nd line is emergancy (Take off power). (default without bombs, 50%), (no overheat conditions)
Il-2s = first line is continuous, 2nd line is boosted. (default, 50%), (no overheat conditions)
Yaks = first line is continuous (no overheat), 2nd line is continuous with 0% rads and overheat (only short time posible to fly like that). (default, 50%),(On Yak7 top speed is 0% oil, 45% watter).
Lagg3 = first line is continuous (no overheat), 2nd line is continuous with 0% rads and overheat (only short time posible to fly like that). (default, 50%)
La5 = first line is continuous, 2nd line is boosted. (default, 50%), (no overheat) 
La5supmax = first line is continuous (sup1 up to 4.5km), 2nd line is boosted (sup2 from 2.5km). (default, 50%), (no overheat) 
La5FN = first line is continuous, 2nd line is boosted. (default, 50%), (no overheat)
I-16 = first line is continuous, 2nd line is boosted. (default, 50%), (no overheat)
Mig3 = first line is continuous, 2nd line is boosted. (default, 50%), (no overheat)
P-40 = first line is continuous (no overheat), 2nd line is emergancy (Take off on overheat low ). (default, 50%)
P-39 = first line is combat (no overheat), 2nd line is emergency (Max Posible on overheat low ). (default, 50%), (40%/60% O/W rads for best speed )
P-47 = first line is combat, 2nd line is boosted. (default, 50%), (no overheat) , (P-47D-28rpmmax = 2550RPM below 7km, 2850rpm abow 7000m)
Spitfires = first line is combat, 2nd line is emergency (boost). (default, 50%), (no overheat)
Pe2s  = continuous power (default without bombs, 50%), (no overheat) 
A-20 = first line is continuous (up to ~95°C oil), 2nd line is emergancy (up to ~105°C oil). (default without bombs, 50%)

 

-MC.202, Bf-109G6, Hs-129, Ju52, U2VS top speed numbers are taken from extracted game data files in ai folder ( luascripts>ai folder , 0 is for no data for that altitude ) , as i dont have that airplanes yet.
-Max ROC chart data is taken from extracted data files in ai folder (luascripts>ai folder) for each airplane, and not from in game test ( so thats mostly climb rate for airplanes at combat power or nominal if they dont have combat ).
-Charts for turn time by speed and ROC at constant TAS have no data taken, so they are empty. 
-In general airplane info (+) is value for turn rate for each airplane taken from :

, or extracted data files from ai folder (luascripts>ai folder) at 0m altitude for airplanes not on JtD test. 
-Data in general info (+) for each airplanes is taken from ai extracted data files ( take off weight value is standard weight taken from airplane in game specs ). Dive max speed values for each airplane are taken from in game dive test from high alt. ( its max speed at point when you first start to lose control parts of airplane , its not max dive speed numbers from in game spec ). Weapons data is not icluded so its not active.

Great job! Many thanks. This kind of data is so usefull for the players. 

Impatient for the new planes like tempest p51 and p38 to compare them with the rest.
