PRINCIPLE OF THE ROCKET ENGINE

WHAT IS ROCKET PROPULSION?

A rocket engine is a propulsion device. Rocket propulsion is a process by which a rocket is lifted from the ground and propelled through the air.  Rocket propulsion is a process that powers a rocket, lifts it from the ground, and propels it up through space. Continue reading this article to learn more about the principle of the rocket engine.

THE ROCKET ENGINE

The rocket engine consists of a combustion chamber, fuels, an oxidizer, and a nozzle. The fuel and the oxidizer are called the propellants, which after being burnt, produce the exhaust from the nozzle. The propellants produce the propulsive forces for continuing to send the rocket up in the atmosphere. The propellant gases are produced in the combustion chamber, from the burning of the propellants, then they are expanded in a nozzle to a supersonic velocity. Thrust is produced from the high-velocity gases coming out from the nozzle, and thus the thrust propels the rocket to go higher in the atmosphere.

HOW DOES THE ROCKET ENGINE WORK?

Modern rockets work through the ignition of the propellant. When the propellant combustion takes place, the gases produced have a high volume. The gases are under great pressure from the heat of combustion, so they are pushed downwards from the nozzle, and they are released from the open end of the rocket at high velocities. The force produced from the ejection of the gases propels the rocket forward. The greater thrust a rocket has, the faster it goes.

HOW DOES THE ROCKET PROPULSION WORK?

The three of Newton’s laws of motion work combined to make the rocket propulsion work efficiently. As written in this article, when the exhaust gases come out downwards from the nozzle, the rocket goes upwards in space. This working principle of a rocket principle is based on Newton’s third law of motion. Newton’s law states that ‘every action has an equal and opposite reaction’. The action refers to the propellant being sent downwards with great velocity. The reaction is the rocket being sent upwards to reach its target.

CONCLUSION

This blog mentions the working principle of a rocket engine, and how the rocket propulsion works. Rocket propulsion is accomplished through the combustion of the propellants, and the blasting of the exhaust downwards, and thus this propels the rocket forward in space.
