  2. Gunpowder - Wikipedia

    en.wikipedia.org/wiki/Gunpowder

    Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.

  3. Ammonium perchlorate composite propellant - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perchlorate...

    Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing ...

  4. Black powder rocket motor - Wikipedia

    en.wikipedia.org/wiki/Black_powder_rocket_motor

    Black powder rocket propellant is very similar in makeup to old-fashioned gunpowder. The main difference is the presence of a binder, usually dextrin. The commonly used Estes model rocket engines are made with black powder propellant. [2] Black powder propellant must be pressed very tightly in order to function well.

  5. Solid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Solid-propellant_rocket

    A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in ...

  6. Pyrotechnic composition - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_composition

    gunpowder – burns slower than flash powder, produces large amount of gases solid propellants – produce large amount of hot gases, used as sources of kinetic energy for rockets and projectiles pyrotechnic initiators – produce large amount of heat, flames, and/or hot sparks, used to ignite other compositions

  7. History of gunpowder - Wikipedia

    en.wikipedia.org/wiki/History_of_gunpowder

    Earliest known written formula for gunpowder, from the Wujing Zongyao of 1044 AD.. Gunpowder is the first explosive to have been developed. Popularly listed as one of the "Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century).

  8. Rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Rocket_propellant

    The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines.

  9. Fire arrow - Wikipedia

    en.wikipedia.org/wiki/Fire_arrow

    The rocket propelled fire arrow appeared later. By the mid-14 century rocket arrow launchers had appeared in the Ming dynasty and later on mobile rocket arrow launchers were utilized in China and later spread to Korea. The fire arrows propelled by gunpowder may have had a range of up to 1,000 ft (300 m). [5]
