Rakettmootorid

Rakettmootorid are rocket engines. A rocket engine is a type of engine that produces thrust by expelling a fast-moving jet of fluid. This thrust can be used to propel a rocket. Rocket engines work based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The action is the expulsion of the propellant, and the reaction is the force that pushes the rocket forward.

The propellant can be a solid, liquid, or gas. Solid rocket motors contain a solid fuel and oxidizer mixture that burns to produce hot gas. Liquid rocket engines use liquid fuel and oxidizer that are pumped into a combustion chamber and ignited. They are often more efficient and controllable than solid rockets. Some rockets use hybrid designs, combining elements of both solid and liquid systems.

Rocket engines are essential for spaceflight, enabling satellites to reach orbit, spacecraft to travel to other planets, and enabling the launch of crewed missions. They are also used in other applications such as fireworks and certain types of high-speed aircraft. The design and efficiency of rocket engines are critical factors in the success of any rocket-powered mission, with ongoing research focused on improving thrust, fuel efficiency, and reliability.
