Eli5: why do fighter jets use less refined fuel than cars

584 viewsEngineeringOther

Cars use gasoline but jets use something closer to diesel, maybe kerosene, that’s less combustible. Wouldn’t they need a _more_ volatile or explosive fuel to get the most thrust for performance?

Just because it’s lower in the distillation tower doesn’t mean it’s less refined. The rules to store and deliver jet fuel are much stricter. The product has very precise and controlled properties, like conductivity, particulate content. The tanks holding it are lined internally, and cleaned much more often. I could go on but I’d have to pull out a standard and I’m tired.
