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.
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 ...
This mixture is typically 69-70% finely ground ammonium perchlorate (an oxidizer), combined with 16-20% fine aluminium powder (a fuel), held together in a base of 11-14% polybutadiene acrylonitrile (PBAN) or Hydroxyl-terminated polybutadiene (polybutadiene rubber fuel). The mixture is formed as a thickened liquid and then cast into the correct ...
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 ...
The highest levels of the chemical were found in popular baby and kid foods, which can lead to thyroid hormone issues, the report found.
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 has long been known to be a problem. In 2005, the Environmental Protection Agency set a daily perchlorate exposure limit of 0.7 micrograms per kilogram of body weight — a dosage that ...
