The type of fuel has a major impact on the performance of the spacecraft. Liquid, solid or gas, these vehicles have different effects.

Bride, What fuels are used in rocket engines? and let’s look at the effects they have.

Rocket engines can use solid, liquid or gaseous fuels.

Two characteristics are very important in the selection of fuels used in space vehicles. The first is is the change in the momentum of the spacecraft caused by a given amount of fuelThe second is the magnitude of the thrust created by the fuel.

However, the fuels used in spacecraft today do not have both of these high efficiency characteristics at the same time. Furthermore, when choosing a fuel; Whether the fuel can be stored easily and safely, its accessibility and its costs is also taken into account.

The thrust capacity of solid fuels is generally high.

For this reason, they are generally used in the initial phase of spacecraft launches. Solid fuels can be stored and transported easily and safely. But once ignited, it is no longer possible to stop the combustion process.

In addition, a certain amount of liquid fuels change in momentum of spacecrafthigher than that of the same amount of solid fuel. For this reason, liquid fuels begin to be used after the spacecraft reaches a certain altitude.

Liquid hydrogen is largely used for this purpose.

Hydrogen is light but a very powerful rocket fuel. Energy is released as a result of the reaction with oxygen. But oxygen and hydrogen can be stored as liquids at very low temperatures..

In addition, to prevent the re-evaporation of hydrogen, the friction effect created by the particles in the atmosphere is counteracted by the particles emitted by the rocket engines. It should be kept away from hot gases and sunlight.
