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 ...
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.
Several propellants were tried in various programs: One of the later (1991) successful gun fuels was a saturated solution of ammonium perchlorate in ammonia.This has a vapor pressure of one atmosphere at 20 °C (68 °F), and generally forms a convenient liquid that is stable and possible to handle.
Gunpowder was extensively used in the Naderian Wars. Around the late 14th century, European powdermakers first began adding liquid during grinding to improve mixing, reduce dust, and with it the risk of explosion. [137] The powder-makers would then shape the resulting paste of dampened gunpowder, known as mill cake, into corns, or grains, to dry.
Propellants packaged in small sheet metal canisters for sale to civilians were labeled Military Rifle Powder to distinguish the product from low-density "bulk" propellants intended to react at lower pressures in shotguns or pistols and from Sporting Rifle Powder for early lever-action rifles unable to withstand the pressures of 20th-century ...
Bulk powders were intended to offer advantages of smokeless powder for use in firearms designed for black powder. Charges of bulk powder are loaded in the same volume appropriate for black powder. Early formulations including partially nitrated cellulose with potassium nitrate or barium nitrate were more successful in shotguns than in rifles.
