What is in rocket fuel????????????

Question

im doing a school project and i need to no wats in rocket fuel and other stuff about rockets

Answer 1

Answer 2

What type of rocket fuel?  They use hydrogen with the space shuttle.  Solid rocket fuel is composed of ammonium perchlorate and aluminum.  Before that was a mixture of charcoal, sulfur, and potassium nitrate.

Other stuff about rockets?  Use an enclylopedia.  Also watch the movie October Sky, it will give you inspiration.

Answer 3

There are way too many types of fuels to discuss.

Here is a good link to different types of rocket fuels.

http://en.wikipedia.org/wiki/Rocket_fuel

If you are talking about space shuttle fuel, it is liquid hydrogen (the actual fuel) and liquid oxygen (which allows the hydrogen to burn)

For small model rockets, the fuel is usually made up of ammonium perchlorate, potassium nitrate and aluminum powder.

Answer 4

Rocket fuel consists mainly of  (liquid oxygen, nitrous oxide, nitrogen hydroxide, and hydrogen peroxide).  Some use liquid oxygen, or liquid hydrogen-liquid oxygen as a propellant.  Anhydrous hydrogen,  These chemicals and chemical compounds are highly flammable as well as explosive.  

Answer 5

One of the most common liquid rocket propellant formulations today is RP-1 (a type of kerosene not unlike jet fuel) and liquid oxygen.

A rocket works by expelling a fluid mass with as much momentum as can be obtained, driving the rocket in the other direction by means of conservation of momentum.  Hence rockets work by accelerating a fluid mass in some way.  The most common way to do that is to cause a material to expand greatly, and quickly, and allow it to escape only through a carefully designed nozzle.  And the most common way to cause something to expand rapidly and greatly is to heat it up considerably.

Hence rocket fuels are, as has been explained, combinations of substances in which those highly energetic reactions can be made to occur.  Those substances can be in liquid, solid, or gaseous forms to start with, or combinations of them.

One important measure of propellants is "specific impulse," which is best thought of as the attained thrust per unit propellant mass.  One of the highest specific impulses in ordinary chemical rockets is liquid hydrogen and liquid oxygen, which is why it is used in the space shuttle and in many upper stages of commercial rockets.

However, solid fuels are sometimes still preferred because even though they have (on average) about half the specific impulse of LOX/LH2, they have greater thrust per unit VOLUME.  When the size of the rocket casing and its associated engineering tradeoffs are important, then solid fuel is a good choice.

Small rocket motors such as high-reliability upper stage motors and steering jets use what are called hypergolic propellants.  The most common formulation of those are nitrogen tetroxide and one of the hydrazine compounds.  These fluids spotaneously ignite on contact, requiring no ignition mechanism.  (Other rockets require something like a spark plug to get them going.)  This makes for simple, very reliable rocket motors.

Answer 6

Rocket fuel is made of 3 things:

Fuel - something that burns

Oxidizer - something that adds oxygen to the fuel to burn harder

Binder - something that binds, or glues, it all together

In solid rockets powdered Aluminum is a common fuel, Potassium Nitrate is a common oxidizer, and Rubber is a common binder.

Without the oxidizer the fuel burns with flames instead of jets of hot gas.

Without the fuel the oxidizer burns too cold and with too little power to do anything.

Without the rubber pockets of air build up in the fuel and when the hot gas gets there it explodes.
