HOW THE AERIAL SHELL FIREWORKS WORK? || PROFESSIONAL FIREWORKS | 3D ANIMATION || LEARN FROM THE BASE

Summary

This video delves into the mechanics of fireworks, explaining the key components and how they work together to create spectacular displays. The mortar tube launches the shell into the air, with the shell containing pyrotechnic pellets arranged in specific patterns to determine the explosion's shape. Gunpowder and a time-delay fuse are used to ignite the burst charge, which then explodes, igniting the pellets. This process results in a stunning aerial display as the pellets burn and expand in the sky, arranged to form different patterns. The video highlights the science behind each stage of a firework's journey from launch to explosion.

Takeaways

• 😀 Fireworks are low explosive pyrotechnic devices used for aesthetic and entertainment purposes.
• 😀 A mortar tube helps launch the firework shell into the air at a perfect angle.
• 😀 The mortar tube is packed with pyrotechnic chemicals to initiate the explosion.
• 😀 The base layer of the mortar is made of clay, while the layer of gunpowder is the lifting charge.
• 😀 Gunpowder, composed of sulfur, carbon, and potassium nitrate, is used as a propellant in fireworks.
• 😀 A visco fuse is used to create a time delay, initiating the function of the firework.
• 😀 The fuse burns at a uniform rate, with a black powder core and textile outer wraps.
• 😀 The aerial shell contains pyrotechnic pellets arranged in specific patterns for different visual displays.
• 😀 The burst charge inside the shell is made of gunpowder and creates the explosion in the sky.
• 😀 Cardboard discs inside the shell help keep it in place within the mortar, ensuring proper sealing.
• 😀 The ignition of the lift charge generates heat and gas that propels the firework shell high into the air.
• 😀 Once the shell reaches a certain height, the time delay fuse ignites the burst charge, causing the pyrotechnic pellets to expand and create the desired display.

Q & A

What is the function of the mortar tube in a firework?

The mortar tube helps the firework shell to ascend into the air at a perfect angle.

What is the base layer of the mortar tube made of?

The base layer of the mortar tube is made of clay.

What is the purpose of the lifting charge in a firework?

The lifting charge, made of gunpowder, propels the firework shell into the air by creating an explosion.

What is gunpowder composed of?

Gunpowder consists of a mixture of sulfur, carbon, and potassium nitrate.

How does the visco fuse function in a firework?

The visco fuse initiates the burning process and creates a time delay before igniting the next component, such as the burst charge.

What is the role of the fuse's outer layers?

The outer layers of the fuse are coated with wax to provide water resistance.

How are the pyrotechnic pellets arranged inside the aerial shell?

The pyrotechnic pellets inside the aerial shell are arranged in a specific pattern that dictates the shape of the explosion when ignited.

What happens when the burst charge ignites?

When the burst charge ignites, it creates an explosion that burns and expands the pyrotechnic pellets, setting off various patterns in the sky.

What is the function of the cardboard discs inside the firework shell?

The cardboard discs help to keep the shell in place within the mortar and ensure proper sealing for the shell.

How does the firework reach its desired height after ignition?

The heat and gas generated from the ignition of the lifting charge cause an explosion, which propels the firework shell as high as 1,000 feet into the air.
