How rocket engine works

A space rocket is a vehicle with a very powerful jet engine designed to transport people or equipment to the world and space. If we define space as the outer region of the Earth's atmosphere, it means that there is not enough oxygen to fill the kind of conventional engine you see in a jet plane.

Therefore one way to look at a rocket is to have a special type of vehicle that is powered by a jet that provides oxygen. What else can we understand about rockets? They require great speed and too much energy to avoid gravitational motion and prevent them from hitting the earth back like rocks. Huge speed and power mean producing great power in rocket engines.

US President John F. Kennedy, in his famous speech of 1962, made his famous attempt to go to the moon, comparing the power of a rocket to "10,000 cars with its speed on the floor". 

According to NASA calculations, the Saturn V Moon rocket "produces 34.5 million newtons (7.6 million pounds) at launch, creating more than 85 Hoover dams."

How rocket engine works

A rocket engine uses stored rocket propellants as a reaction to create a high-speed propellant jet of liquid, typically high-temperature gas. Rocket engines are reaction engines, which emphasize Newton's third law. 

While most rocket engines use the combustion of reactive chemicals to provide the necessary energy, non-combustible variants such as cooled gas thrusters and nuclear thermal rockets also exist. 

Vehicles powered by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizers unlike most combustion engines, so rocket engines can be used to circulate spacecraft and ballistic missiles in a vacuum.

Compared to other types of jet engines, rocket engines are the lightest and most stressful, but the least propellant-efficient (they have a specific tendency). Standard extraction hydrogen, the lightest of all components, but chemical rockets form a mixture of heavier species, reducing exhaust velocity.

Artwork: The force acting on an airplane (left) and a rocket (on the right). When an aircraft flies at a constant speed, the forward thrust generated by the engine is equivalent to pulling back the air resistance (pulling). The upper strength of the lift created by the wings is equal to the force under the weight of the aircraft. 

In other words, the two pairs of forces are in perfect balance. With the rocket, the weight of the engine is pushed upward during the run and pulls down and tries to pull it down. When the rocket moves upward, the joints are higher than the joint lift and bridge. 

Various surfaces of rockets can also be lifted like the wings of an airplane, but they work shoulder to shoulder instead. While this seems confusing, it's easy to see that if you imagine a blue plane rotating by 90 degrees, it's going straight up.
Rocket: The elevator must also be pointing sideways.

Jet engine Physics

The rocket engine, design varies depending on height, height, thrust, and other factors.

The carbon bodies of kerosene fuels are often orange in color due to black-body radiation of unbalanced particles, with blue goose bands. Peroxide oxidizer-based rockets and hydrogen rocket jets contain too much vapor and almost disappear to the naked eye but shine on ultraviolet and infrared. 

The jets from a hard rocket can be extremely visible as propellants often contain aluminum-like metals that add energy to the process of burning and combustion in orange-white flames.

Some fatigue, particularly alcohol-fueled rockets, may show visible diamonds. This is due to the cyclic change in jet pressure associated with the shock waves that surround the formation of the 'match disc'.

The size of the jet varies by design height: at altitude, all rockets are permanently stretched and the percentage of exhaust gas is quite low.

Principle of operation

Rocket engines force the exhaust fluid to accelerate at high speeds through an exhaust nozzle. The liquid is a gas that is usually produced from the combustion chamber, which contains high-pressure (150 to 4,350-lb-per square inch (10 to 300 bar)) combustion, fuel, and combustion material of solid or liquid propellants. 

As the gases expand through the nozzle, they accelerate at very high (supersonic) speeds, and the reaction pushes the engine in reverse. Combustion is often used for practical rockets, as higher temperatures and pressures are desirable for optimal performance.

The combustion model is a rocket water rocket, which uses compressed air, carbon dioxide, nitrogen, or any other readily available, inert gas pressurized water.
