Rocket candy, or R-Candy, is a type of rocket propellant for model rockets made with a form of sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the (optional) additive(s). In the past, sucrose was most commonly used as fuel.
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.
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.
Solid rockets use propellant in the solid phase, liquid fuel rockets use propellant in the liquid phase, gas fuel rockets use propellant in the gas phase, and hybrid rockets use a combination of solid and liquid or gaseous propellants. In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast.
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 ...
The rocket, developed by United Launch Alliance, uses the Blue Origin's BE-4 engine, though the second stage uses the hydrolox RL10. New Glenn successfully reached orbit on its first try on 16 January 2025. The rocket and its engines are developed by Blue Origin. The first stage uses BE-4 engines, and the second stage uses the hydrolox BE-3U.
Perchlorate, a chemical found in rocket fuel, has contaminated water and food and is more likely to be found in food given to babies and children, a study from Consumer Reports found.
The highest levels of the chemical were found in popular baby and kid foods, which can lead to thyroid hormone issues, the report found.
