Solid-propellant rocket - Wikipedia
Rocket Candy , or R-Candy , is a type of rocket propellant for model rockets made with sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the additive s. In the past, sucrose was most commonly used as fuel. Modern formulations most commonly use sorbitol for its ease of production. The most common oxidizer is potassium nitrate KNO 3. Potassium nitrate is most commonly found in household stump remover.
Engine Hacks: Liquid Fuel Amateur Rocket Roundup
When the idea of an engine hacks theme was being kicked around at Hack a Day, the subject of rocket engines was one of the first to come up. First up is [Robert Watzlavick], who has been has been building liquid fueled engines for the last decade. As with many of the early rockets that launched man into space, [Robert] uses kerosene and liquid oxygen for fuel.
Introduction T here are certainly countless solid propellant formulations that have been tried by amateur experimentalists over the years. Some have been very successful and have gained worldwide popularity, although undoubtedly most formulations have been simply downright failures, or at best, marginally successful. Surely anyone who has ever been involved in AER can cite formulations that they have tried without success, including myself.
