In summary, the conversation discusses the physics behind pyrotechnics, specifically how to determine the height and path of an aerial shell when fired at an angle. Factors such as propellent, velocity, and mortar size are mentioned, and the conversation ends with a request for formulas to help with calculations.

Does anybody know any information reguarding the physics behind pyrotechnics?
Such as:
1. Figuring the height an aerial shell (projectile) will reach.
2. Graphing the path of the shell (projectile) when fired at an angle.

I understand what factors influence the answers to these questions, I just don't know how to put it all together.

Some factors that I know of would be:
1. The amount of propellent used to send the shell into the air.
2. The maximum velocity of the projectile.
3. The size(height, width) of the mortar from which it is fired.
4. Drag, Gravity, Weight, Speed etc..

Some formulas for figuring these out would be greatly appreciated.

Chris

Thanks.. Good page.
 

1. What is the basic principle behind the physics of pyrotechnics?

The basic principle behind pyrotechnics is the rapid release of energy in the form of heat, light, sound, and gas. This is achieved through the combustion of chemical compounds, which produce a controlled explosion.

2. How do pyrotechnic devices create different colors?

Different colors in pyrotechnic displays are created by adding various metal salts to the chemical compounds. When these salts are heated, they emit specific wavelengths of light, resulting in the different colors that we see.

3. How do pyrotechnic devices create different shapes and patterns?

The shapes and patterns in pyrotechnic displays are created by using different types of shells and fusing techniques. Different shells, such as spherical, cylindrical, or star-shaped, produce different visual effects. Fusing techniques allow for the timing and placement of the shells to create specific patterns.

4. What role do oxygen and other gases play in pyrotechnic displays?

Oxygen is a crucial element in the combustion process of pyrotechnics. It provides the necessary amount of oxygen for the chemical compounds to burn and produce the desired effects. Other gases, such as carbon dioxide and nitrogen, can also be used to control the speed and intensity of the reaction.

5. How do safety measures play a role in pyrotechnic displays?

Safety is a crucial aspect of pyrotechnic displays, both during the preparation and execution. Before the display, proper handling and storage of the chemicals are essential to prevent accidents. During the display, safety measures such as protective gear and proper distance from the devices are necessary to ensure the safety of the pyrotechnicians and the audience.
