Rocket Fireworks

2023. 02.07

A rocket is a pyrotechnic firework made out of a paper tube packed with gunpowder that is propelled into the air. Types of rockets include the skyrockets, which have a stick to provide stability during airborne flight; missiles, which instead rotate for stability or are shot out of a tube; and bottle rockets, smaller fireworks – 1½ in (3.8 cm) long, though the attached stick extends the total length to approximately 12 in (30 cm) – that usually contain whistle effects.

The most commonly known type of firework, when launched into the air the Rocket can climb to an enormous height. Depending on the type of rocket used, some can reach 30 - 60 metres before exploding with a loud bang (also known as a report)

Gunpowder's relatively low specific impulse (amount of thrust per unit propellant) limits its capacity of thrust production on larger scales. Fireworks are the simplest of solid rockets and the weakest. Evolution from fireworks brought about more complex solid-fueled rockets, which use more exotic and powerful fuels. The low-explosive properties of gunpowder, relative to the high-explosive properties of more advanced solid fuels testify to the "survival of the fittest," as the use of firework-type engines (for purposes other than entertainment or education) has virtually ceased since the late nineteenth century. Yet with all these drawbacks fireworks will continue to maintain their use as a traditional pastime.
