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.
Sugar based rocket propellants have an average I sp (specific impulse) of between 114 and 130 seconds. Compare that to the average I sp of an APCP (Ammonium perchlorate composite propellant), which is 180 to 260 seconds. Sorbitol and KNO 3 based propellants with a typical 35:65 ratio are capable of an I sp of between 110 and 125 seconds.
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.
Perchlorate is a chemical compound with a variety of uses — and it’s indeed a component of rocket fuel, according to John D. Coates, Ph.D., director of the Energy & Biosciences Institute at ...

In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast. Propellant combustion occurs inside the motor casing, which must contain the pressures developed. Solid rockets typically have higher thrust, less specific impulse , shorter burn times, and a higher mass than liquid rockets, and additionally cannot be ...
Foods tested for perchlorate. According to the study, researchers analyzed "196 samples of 63 supermarket products and 10 fast food items." These product categories had the highest levels of ...
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.
