Personally I like to give my FJ's an airco with the heat on Crete but merciless pilots who want them to sweat just leave the door closed.
And closing the door also changes the seating animation of soldiers in the plane

Are you sure?

Pretty sure. I atleast remember 2 different 3d animations for players seating in the Junkers. 1 facing the roof and 1 facing their knees.

I think that those animations are connected with the speed of descent of the plane.

What I forgot to write early this morning (sorry it was 3 AM) was that we were basically fighting for the same thing. You were fighting to show that lead increases octane to increase engine power and I was fighting to show that Lead was put into gasoline in order to be able to increase compression ratios of engines (or add something that pre-pressurizes the air going into the cylinders) to increase power.

Problem is that neither of us had a real understanding what octane did for gasoline. In my case I had learned about "octane" in chemitry but only how it was represented, Guess the education system failed somewhere along the line :lol:.

So yeah In the end we both were fighting for the same thing but I didn't notice until your last post when you were talking about being able to increase the gearing ratios of the Superchargers when the octane level was increased.

Well I guess the rest of the FH-ers will be happy that we are moving away from the "Getting too technical" conversation.

As for the exam I understand what you mean I've got 4 days till my exam and I'm hoping to be able to pry myself awayfrom this site enought to actually study.

You are right- we both reached the same conclusion with the same reasoning, and although it didn't manifest itself as being the same when it was written, looking back the arguments were basically identical. Octane is simply a rating of a chemicals resistance to pre-detonation. Highschool chemsitry wise it raises the compound's activation energy.

Predetonation is aggravated by high tempuratues and pressures. Very high compression ratios in naturally aspirated engines, and high boost levels in forced induction motors both nessesitate high(er) octane fuel.

Diesel engines dont predetonate because as you said they only intake air. They are however forced to endure miniature explosions with each injection of fuel. They are beefed up internally to withstand the strains imposed on them.

Thank goodness we settled that!

P-39 was not a low level attack plane! The soviets almost NEVER used it as such, they used it primarily as a normal fighter plane. It was superior to the 109 and Fw190, and the top Russian aces all scored majority of kills on the P-39. Tis a sin to assume that it was a "low level attack plane."

And some can get really creepy

Exactly the Diesel engine sprays the fuel into it only after the air is compressed to the point that is required. By doing this you are using auto ignition to help you rather than hinder. Because this is done you can use inferior fuel in the engine thus making it burn a cheaper fuel. Only problem is, is that you need a stronger fuel pump to be able to add the fuel to a pressurized piston, and In cold weather you need glow plugs to warm up the air so that the fuel will auto-ignite.

Slain by Mudra! I knew in the back of my mind that he would get me for something. :lol: In my defense I never called it a ground attack plane, rather I left it more ambiguous --attack plane could also mean an air to air fighter. The crux of the matter was really that the Soviets did not employ it at altitude. It spent most of its time attacking German fighters below ~12,000 feet.
