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.
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 ...
Ejection charge (commonly Black Powder), [1] also called expelling charge, is a pyrotechnic composition, a type of a pyrotechnic gas generator designed to produce a small short-term amount of thrust to burst open a container and eject its content. In model rocketry, ejection charges are used to deploy a recovery system (usually parachute or ...
At this time, amateur rockets nearly always employed either black powder, zinc-sulfur (also called "micrograin"), or rocket candy (often referred to as "caramel candy") propellant mixtures. [5] However, such amateur rockets can be dangerous because noncommercial rocket motors may fail more often than commercial rocket motors if not correctly ...

In comparison with black powder, BPN burns significantly hotter and leaves more of solid residues, therefore black powder is favored for multiple-use systems. BPN's high temperature makes it suitable for uses where rapid and reproducible initiation is critical, e.g. for airbags, rocket engines, and decoy flares. It is however relatively expensive.
