Rocket space
A rocket is a machine, using a combustion engine, produces the kinetic energy required for the expansion of gases that are released through a drive tube(called jet propulsion). By extension, the vehicle, usually space propulsion enginethat has this type is called a rocket or missile. Normally, your goal is to sendartifacts (especially artificial satellites and space probes) or space ships and men to space (see atmosphere).
A rocket consists of a structure, a jet propulsion engine and a payload. The structure serves to protect the fuel and oxidizer tanks and payload. Also calledrocket propulsion engine to itself.

operation
The operating principle of the rocket engine is based on Newton's third law, thelaw of action and reaction, saying that "every action there is a reaction, with thesame intensity and opposite direction."
Imagine a closed chamber where there is a burning gas. The burning of gas will produce pressure in all directions. The camera does not move in any directionas the forces on opposite walls of the chamber void.
If we practice an opening in the chamber where the gases can escape, there be an imbalance. The pressure on the opposing side walls continue without producing force, as pressure from one side to the other void. And the pressureat the top of the camera will produce thrust, as there is no pressure on the underside (where the opening).
Thus, the rocket will move up in reaction to pressure from the combustion gases in the combustion chamber of the engine. Therefore, this type of engineis called jet propulsion.
As in outer space there is no oxygen to burn fuel, the rocket must carry not onlystored in the propellant tanks (fuel), but also the oxidant (oxidizing).
The magnitude of thrust produced (expression for the force produced by therocket engine) depends on the mass and velocity of the gases expelled through the opening. Then, the higher the temperature of the gases expelled, the greater the thrust. Thus, the problem of protecting the combustion chamber and the opening of the high temperatures produced by combustion. A clever way todo this is to cover the walls of the engine with a fine jet of propellant used byitself to form a rocket insulation and cool the motor.
