Different types of jet engine
s use different types of aviation fuel
. The typical turbine
fuel is JP-5
, which is akin to a thin kerosene
. You can put out a cigarette
in it, it won't blow up. The problem is if you get it to warm
up and begin to evaporate
, wherein the fast combustion takes over.
Another type of fuel is called Avgas, which is a very high octane gasoline (I've seen it run 131 r+m octane). Some idiots put it in their cars and lament the hulks of their ex-engine blocks after the explosion blows off the cylinder heads. A cheap way to do this is to add mothballs to gasoline, the dead vehicle result is the same.
Jet engines have fskloads of acceleration. The problem is trying to lift a hulking airframe off of the ground, like a 747. Creating enough inertia to get it going takes tons of thrust. V/STOL aircraft use jet engines, and they can take off vertically, as in the Harriers. Without the monster thrust, they'd just bob up and down on their tires.
