Related to bipropellant: monopropellant


A two-component rocket propellant, such as liquid hydrogen and liquid oxygen, fed separately to the combustion chamber as fuel and oxidizer. Also called dipropellant.


(Astronautics) a rocket propellant consisting of two substances, usually a fuel and an oxidizer. Also called: dipropellant Compare monopropellant


(ˌbaɪ prəˈpɛl ənt)
