Black powder rocket motors are only produced in small sizes, to reduce the risk of explosion and a loss of efficiency. Black powder rockets are produced in classes 1/8 A through F. Larger sizes of model rocket motors use ammonium perchlorate composite propellant, or other composite fuels that contain ammonium nitrate.
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 ...
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 ...
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.
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.
A 1682 demonstration of Huygens gunpowder engine, where a dram of gunpowder creates enough vacuum to lift 8 boys into the air. Huygens, however, became interested in the mechanical power of the vacuum, and the possibility of using gunpowder to produce one. In 1678 he outlined a gunpowder engine consisting of a vertical tube containing a piston ...

Still, black powder remains in use for certain types of firearms, including historical weapons from before the invention of smokeless powder, such as muzzleloaders. Black powder substitutes are propellants designed to provide explosive force similar to that of black powder, primarily for use in such firearms, despite being legally classified as ...
