Are liquid fueled rockets still used today?

Answer 1

Solid, hence the name. The propellant in the solid rocket boosters on the US Space Shuttle is composed of ammonium perchlorate, powdered aluminum, iron oxide, and a polymeric binder to hold it all together. There are other possible mixtures as well.

Answer 2

virtually any combination of an oxidizer and fuel can be used as rocket fuel

there are many different type of rocket fuel,

there are three primary types of chemical rockets

Liquid rockets-

Oxidizers:

LOX (liquid oxygen)

N2O2

Hydrogen Peroxide

Fuels:

hydrazine

gaseous Hydrogen

Liquid Hydrogen (cryogenic)

ammonia

RP-1 (similar to Kerosene)

Alcohol

Ethanol

Solid rockets-

Early solid rockets were used in ancient times as fireworks and weapons by the Chinese

they used black powder as fuel

modern solid rockets used a verity of fuels but the most common consist of:

Oxidizers:

Ammonium prechlorate

Ammonium Nitrate

Sodium nitrate

Potassium nitrate

Potassium perchlorate

Nitronium prechlorate

hybrid rockets-

hybrid rockets consists of a liquid oxidizer and a solid fuel most use a combination of the previously listed fuels some hybrids use Nitrous Oxide (laughing gas) and HTPB (a form of rubber) waxes can also be used as a fuel

other rocket motor types include

nuclear rockets (detonation rockets or radioactive hydrogen)

Electrostatic propulsion - Uses electrodes and Electrons to propel a spacecraft

they are low thrust high impulse engines

Ion rockets- use xenon or neon gas ions and electrodes to propel a spacecraft

they are low thrust high impulse engines

some conceptual rockets include

Anti-proton and positron antimatter rockets

Answer 3

Rockets use a self contained system of fuel and oxidants as there is no air for combustion once the rocket is out of the Earth's atmosphere. Typically this is a fuel such as hydrogen or letroleum distillates and an oxidant such as liquid oxygen or hydrazine. Alternately a solid rocket using a mixture of solid chemical oxidants and fuel is employed.

Jet engines are not useful as the weight to thrust ratio is poor, the fuel requirements are prohibitive and they would have to be discarded at some point in the flight.

Answer 4

Solid fuel, liquid fuel, and electrically charged particles of gas.

Another answer: If you want details of chemicals used, you could look at the Wikipedia page called "Rocket propellant".

Answer 5

There are a number of different rocket fuels in use. Some of the considerations for selecting a rocket fuel are;

1. How much energy per pound does the fuel contain?

2. What kind of storage and handling requirements does the fuel have?

3. Is the fuel stable on the launch pad?

For example, the Space Shuttle uses liquid hydrogen and liquid oxygen, both of which are extremely cold. Additionally, hydrogen is very difficult to keep confined; as the smallest atom, it will leak through impossibly small cracks. It has high energy content, but is touchy and requires a LOT of effort and maintenance. The Shuttle cannot be kept fuelled on the pad.

The SpaceX rocket uses kerosene, which has a lower energy per pound, but isn't as touchy and not as leaky.

The SpaceShipOne Anasari X-Prize rocket used a fuel made from recycled tires.

Answer 6

I just took the test the answer is

Ammonia

Answer 7

Gas propellants generally aren't used, but you're probably thinking of liquid hydrogen. Hydrazine and kerosene are also frequently used.

Answer 8

There are a number of options. NASA often tries to employ exotic fuels, with significant problems in transportation and maintenance. Most commonly used are liquid hydrogen and liquid oxygen.

Answer 9

Some are solid fuels, similar to gunpowder. Some are liquid fuels, such as alcohol, kerosene or liquid hydrogen.

Answer 10

They are very rarely used.
