The Catalan word coet derived in rocket , a concept that has several meanings in our language . A rocket can be a device that travels through the air at high speed and uses a cone weapon .
These rockets usually have a reaction engine (known as rocket engine ) that, through the gas expulsion which come from its combustion chamber, produces the movement . They can also be driven by a propellant charge which is burned inside the launch tube.
Rockets are also machines that, thanks to a combustion engine , generate the Kinetic energy which is required to expand certain gases that they expel through a tube. That's why they say they have propulsion to reaction . The spacecraft that appeals to this type of propulsion is also often referred to as a rocket.
With a rocket it is possible to send probes and artificial satellites to outer space, and even to astronauts .
In this sense, we cannot forget the existence of what is known as a space rocket. This is a machine equipped with a combustion engine that produces kinetic energy for the expansion of gases with which to have jet propulsion.
There are several types of space rockets, the most important being the following:
-If we consider the number of phases, we find the one-phase rocket, also called monolithic, and the multi-phase rocket. This has, as the name suggests, several phases that are happening sequentially.
-If we consider the type of fuel, we run into the solid fuel rocket, where the oxidant and the propellant are mixed in a solid state inside the combustion chamber, and the liquid fuel rocket. The latter is characterized in that the oxidant and propellant are stored outside what is said chamber.
Throughout history there have been important rockets because they have managed to take man into space. We are referring to some such as the following:
-Vostok-K 8K72K, which is the first manned rocket. It was performed in Russia and was responsible for making Yuri Gagarin the first man who came to space.
-Atlas LV-3B. An American rocket that made John Glenn the first man to reach what is the Earth's orbit.
-Saturn V, the rocket that took Neil Amstrong, Michael Collins and Buzz Aldrin to the Moon.
Also called rocket to pyrotechnic element It presents a tube with gunpowder, which adheres to a rod. The cylinder has a wick in its lower part: when ignited, combustion expels gases and causes the rocket to ascend with a lot speed , until it explodes in the air generating a very loud noise.
