Liquid bipropellant applications

Applications. To date, the liquid propellant systems used in chemical propulsion range from a small trajectory control thruster with only 0.2 lbf (0.89 N) thrust for orbital station-keeping to large booster rocket engines with over l. 0 million lbf (4.44 MN) thrust. Bipropellant propulsion systems are the most extensively used type today for... 

A monopropellant is a fuel that is capable of reacting exothermically without an oxidizer. Numerous such fuels are known many are liquids. A droplet of liquid monopropellant can burn in an inert atmosphere without an oxidizer. There are rockets that employ liquid monopropellants as fuels for propulsion in some applications these are better suited than bipropellant rockets that employ a liquid fuel and a liquid oxidizer. The relevance of monopropellant droplet combustion to the operation of monopropellant rockets and fundamental curiosity have prompted studies of the subject.
