Friday 2010-12-10 Dev. video update and Discussion

S!

Thank you for the update Nice to see things shaping up. In that DB605 video you can see the root of the flame has reddish/yellow but the tip of it is blueish. Could the British and German difference be that Brits and other allies had carburettors and Germans had direct fuel injection in their DB/Jumo/BMW engines. The mixture in a fuel injected engine, like DB-series, is better than in a carburettor engine and high pressure spray of fuel gives more even fill of the cylinder at the right time compared to the suction in a carburettor system.

Also many nightfighter books I have read state blueish flames on British bombers. And there was a talk witha guy who tuned/maintained DB engines and he said the engine tunes were done in a dark room to see the exhaust flame color to adjust the injection etc. correctly.

Ok, have a good weekend all!

Please read with atention: The color of exhaust from the direct pipe and from the extended are different. The temperatue of the flame decreasing with the longer leght of pipe. More lower temperature - more red flame. The most hight is right from the hole without pipe.

As I told above a lot of factors is present in forming of color.

It was already in IL2, so should be the same in SOW.

Try taking a late war 109 for a spin and see how fast it runs out of the good stuff (30mm hub cannon). The only planes that seem to have "Hollywood" levels of ammo are the larger American fighters like the Corsair, and P-47. If you opt for the P-47 with extra ammo you can hold down the trigger the entire length of your mission and still land with enough lead in the guns to down a bomber.

I imagine that Oleg and Co. have figured out the exact historical loadout for all the fighters involved and you won't be given an extra round.

I just clocked it(UP2.01 MkI).

1st: You're right
2nd: I am an Idiot, should have done that before.
3rd: deleted my post - to save space and the original is quoted anyway.

Sorry.

S!

If comparing Spitfire Mk.I/Hurricane early marks and Bf109E-4 it can be easily seen that the Spitfire/Hurricane have longer exhaust pipes than Messerschmitt. I recall reading the exhausts on a DB engine were very short, in range of 10-15cm only.

Don't forget that in the Daimler video, (as far as it seems to me) they were starting the engine for the first time, so they went straight into a "break in run" at a much higher than Idle RPM. (it's been a long time since I've built an engine, but I think I'd typically "run in" a chevy big block at about 2000 RPM for about 15 minutes) That kind of RPM will of course produce a hotter flame than a typical start to idle of an already broken in engine. This will also (as Oleg pointed out ) explain the difference between the flame seen at start up and in flight.

Big LOLs. Oleg sure has his work cut out for him. I'd not be surprised if this thread doesn't cure him from appeals to us for help!

Mr. Maddox, a quick question on last weeks update; Was the map in the FMB a temporary version, or does the SoW map have structures from after the war? (Like the Basin de L'Atlantique at Gravelines, WSW of Dunkerque?)
