Monopropellants
Monopropellants are chemical substances used as fuel in rocket propulsion systems that decompose spontaneously to produce thrust without the need for an oxidizer. These substances typically consist of a single chemical compound that decomposes through a chemical reaction to generate hot gases, which are then expelled through a nozzle to create thrust. Monopropellants are commonly used in small thrusters for spacecraft attitude control or station-keeping maneuvers.
