What happens inside the rocket when taking off?

An American engineer who discovered the process occurring inside the rocket when taking off was recorded by slow motion.

The rocket engine is cut in half and placed in a transparent box for recording. This modern rocket is shot at 1,500-4,000 frames per second using a high-speed camera. The video revealed the rocket's burning process inside the hard case with a hard-to-destroy design, Longroom reported today.

Like most engines, missiles burn fuel, and most missiles turn fuel into hot gas. The engine pushes gas out from behind, causing the rocket to rush forward. There are two main types of rocket engines. Some use liquid fuel as the engines on the shuttle orbit. Other missiles use solid fuels like fireworks or model rockets.

Slow-motion video of rockets fired by Matt Mikka posted on YouTube channel Warped Perception using standard Estes model rocket engine."I used to own model rocket engines and wondered how the rocket propulsion engine went into the air as well as what happened inside," Mikka said.

Mikka made a transparent shell for the rocket engine to be able to film. He used tape to fix the rocket engine inside the box. The fire didn't burn through the plastic box that emitted from the burning fuel inside the chamber.

According to Mikka, the rocket smells sulfur and is not too hard to smell. He also repeated the experiment to see the shape of the fire erupting from the tap.
