A typical liquid engine uses hydrogen as fuel and oxygen as oxidant; a typical solid propellant is nitroglycerine. In the liquid engine, the fuel and oxidant are stored separately at extremely low temperatures; in the solid engine, the fuel and oxidant are intimately mixed and loaded directly into the combustion chamber. A solid engine requires an ignition system, as does a liquid engine if the propellants do not ignite spontaneously on contact.

Lets first clarify the question as it would be more logical to ask it as two different questions:
1) What fuel is used in Jet engines (typically turbine driven compressor rotary jet engines such as the ones used in aircraft) - This would be a middle distillate refinary cut of similar or slightly higher volatility to kerosene
2) What fuel is used in Rocket engines (used in Rockets to launch satelites, nuclear bombs, etc) - These come in two types - Solid fuel and liquid fuel propelled. Solid fuel rockets use some combination of oxidising agent and fuel in a resin base (also a fuel) - typically alluminum and ammonium perchlorate in a resin matrix. Liquid fuel rockets typically use liquid oxygen (as an oxidising agent) and liquid hydrogen (though they can use other fuels such as ethanol ormethanol - eg German V2 rockets or liquid fuels based on petroleum).

Hope that helps....

Jet fuel in jets and rocket fuel in rockets.

that depends on the rocket of course :p
The space shuttle uses liquid hydrogen and oxygen in its main engine. If you ever watch a launch you'll see that the flame out of teh main engines is barely visible..hydroigen flames are not very bright.
The early rockets used kerosene and oxygen. if you watch teh early titan and atlas launches in the 60s, the flame is huge and brigth orange.
The Saturn V moon rocket used kerosene/oxygen in its first stage and hydrogen/oxygen in its 2nd and third stages
The small RCS rockets that maintain spacecraft orientation and allow for maneuvring in space use hydrazine as fuel.
That's why after a shuttle landing, the astronauts wait inside the shuttle for quite a while, while ground personel empties teh remaining hydrazine from its RCS system, since it is highly toxic

jet/rocket fuel is what it's called

jet fuel

like a 747 if so all jet fuel is diesel fuel or kerosen

ROCKET FUEL CONSTITUTES OF FUEL+OXIDISER
FUEL : SOLID ; LIQUID
OXIDISER : OXYGEN

NOTE:
THE USE OF OXIDISER IS DUE TO THE LACK OF
OXYGEN IN SPACE
