What is a rocket ?

  • 1 Answer(s)

    A rocket is a device which produces thrust with the help of a propulsion system to carry a payload. The propulsion system consists of fuel and oxidizer. Both fuel and oxidizer are contained inside the rocket. Unlike in the aircraft where the surrounding air is used for combustion purposes in the combustion chamber, rockets carry both oxidizer and fuel with it. Aircraft engines are called air-breathing engines. Rocket engines are called non-air-breathing engines. In the rocket, the combustion process happens through the combustion of fuel and oxidizer which are called propellants. Rocket works on the principle of Newton’s third law of motion, which states that for every action there is an equal and opposite reaction. Combustion exhaust of high temperature and pressure passes with a very high velocity from the rocket nozzle, which produces an upward thrust. Rockets are of a single stage or multiple stages. Rockets are used to carry payloads like satellites, however, if the payload is a warhead it is called a missile.
