6,300 degrees fahrenheit which is the same temperature as the oxy-acetylene cutting torch flame and in fact the oxy-acetylene cutting torch flame looks exactly the same as the rocket engine flame. Vincent Majerowicz
The rocket carries its own supply of oxygen with which to burn the fuel.
A device that ignites the fuel & oxidizer mixture in the rocket engine when a "burn" is to begin.it lights the rocket.
air
You only have a few choices: -- reduce the total weight (mass) of the rocket and its payload -- burn fuel faster -- burn fuel at the same rate but use fuel with a greater specific impulse
oxygen is added from a separate tank
A rocket motor (rocket engine) does not need air from the atmosphere. It carries the oxidant (source of oxygen) as well as the fuel.
The correct term is "solid propellant rocket". These are rockets that burn fuel that is not a liquid(or they are NOT liquid fuel rockets). These rockets have a fuel that is poured into the rocket case and turns to a solid. Once ignited, there is no stopping the burn or controlling it.A simple example of this is rocket you shoot on the 4th of July. It burns black powder that has been formed into a cardboard case.Whereas, a liquid fuel rocket can be controlled by varying the amount of fuel that is injected into the rocket motor.
gasoline along with liquid oxygen, so the fuel can burn
Since there is no air in space, the spacecraft must bring an 'oxidizer' with it into space. That oxidizer mixes with the fuel, providing the oxygen needed for it to burn, and it burns..
A small rocket might go higher because a smaller rocket has less weight
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.
