Technologies of creation of rocket engines are one of important elements in space exploration. Lately many types of similar mechanisms were created. As a rule, these designs are used in military industrial complex and also in the space industry. About how modern rocket engines are created and also about their classification we also will talk in this material.
Instruction
1. Now rocket engines happen a different look. As a rule, they are classified by the form by fuels. There are chemical rocket engines. Work of gases from reaction of burning of various chemical fuel is their cornerstone. By the principle of action, these rocket engines are completely similar to jet engines. There are also nuclear and thermonuclear rocket engines. Here energy of the engine turns out thanks to reaction of nuclear disintegration or thermonuclear synthesis. It should be noted that thermonuclear engines are not used in practice because of imperfection of technologies yet. There are also still electric and plasma rocket motors.
2. There is no sense in detail to stop on creation of each of these types of rocket engines. In principle, all of them are created on one template and essentially fuels differ only by the form.
3. All engines consist of combustion chambers where there is a creation of the reactive stream setting a rocket in motion. Also in some rocket engines it is used besides fuel also other substances making this stream. As a rule, it is liquid oxygen. In the plasma engine working substance in the combustion chamber is brought to a full condition of plasma that provides bigger efficiency. The combustion chamber is followed already by a nozzle in which the reactive stream and also a draft vector is completely formed. It should be noted that in plasma engines as the accelerator also magnetic field is used.
