Propulsion type
WebbLiquid propellants used in rocketry can be classified into three types: petroleum, cryogens, and hypergols. Petroleumfuels are those refined from crude oil and are a mixture of complex hydrocarbons, i.e. organic compounds containing only carbon and hydrogen. WebbOne type is the double-base, which consists largely of nitroglycerine and nitrocellulose. It resembles smokeless gunpowder. The second type, which is now predominant, is the composite propellant, consisting of an oxidizing agent, such as ammonium nitrate or ammonium perchlorate intimately mixed with an
