Title: WW2 aircraft engines, and modern gas.
Post by: GtoRA2 on July 05, 2005, 04:17:57 PM

So modern av gas is not as high of an octane as you could get durring the war right?


So if not how much does the effect the Horse power of the engines?


The thread on the A-26 landing on one engine got me thinking, at first it seemed like only a slightly big deal, durring the war this happend all the time the engine still running would bring the plane home.

But is that the case now or are they so down on power this was a truely life threatening event?


What would a 2000 HP R28000 be producing now on modern gas?



Do they do anything to the motors to make the run better on this lower octane fuel?

Am I way out in left field here and showing my ass?

Last time I was at the airport fooling with planes, you could still get very high octane aircraft fuel, with a reasonable amount of lead.

The biggest difference, not the only difference, but the biggest difference, between very high octane gas for race cars and very high octane gas for aircraft is the point at which "vapor lock"
will occur.

Aircraft operate at high altitudes and low temperatures. At least the fuel has to be formulated for operation there.

Just add a dose of toluene to the gas -> high octane.
