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 ...
Ammonium perchlorate ("AP") is an inorganic compound with the formula NH 4 ClO 4.It is a colorless or white solid that is soluble in water. It is a powerful oxidizer.Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant.
A perchlorate is a chemical compound containing the perchlorate ion, ClO − 4, the conjugate base of perchloric acid (ionic perchlorate). As counterions, there can be metal cations, quaternary ammonium cations or other ions, for example, nitronium cation (NO + 2). The term perchlorate can also describe perchlorate esters or covalent ...
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.
In 1997, ammonium perchlorate was discovered in a number of domestic water supply wells that serve several water purveyors throughout San Bernardino and Riverside counties. Two of the wells in the City of Loma Linda's municipal drinking water system had been impacted by the perchlorate groundwater plume, originating from the Lockheed site. [1]
Supplier delivery times lengthened a bit, which was blamed on labor shortages. A gauge of prices paid by manufacturers for inputs vaulted to 59.1. That was the highest level since November 2022 ...
Other rarely used oxidizers are ammonium and potassium perchlorate. Two main issues need to be addressed with respect to the oxidizer if one is using potassium nitrate. The most important issue is the purity of the material. If a purchased material does not perform satisfactorily it may be necessary to recrystallize the KNO 3. The second ...
