What is the composite of jet fuel, is it similar to say formula one fuel that is highly concentrated with alcohol (extremely volatile correct me if I'm mistaken) I'm thinking its a low combustion fuel due to the intense heat generated by the engine. Example, I've read that if you dropped a match on the fuel desiginated for an SR-71 it would extinguish the match.

As always keep up the great work,

Hi Chris,

I'm not sure of the fuel composition but I think it is similar to the fuel used in F1 cars. With regards to the fuel used in the SR-71, it's true that a match will not ignite it if it's dropped on it. The fuel used was called JP-7 which had a high flash point but it was mainly developed to cope with the SR-71's heat problems when flying well above supersonic so the plane would not explode, or something like that.

Hi Chris

It's actually more like diesel fuel. The octane rating in jet fuel is pretty high and a lot of additives has been added to give it a high flamepoint. Most fighters actually use the fuel to cool different stuff down so it can get pretty hot.
