1949 G. P. Sutton Rocket Propulsion Elem. v. 115 Monopropellants are stable at ordinary atmospheric conditions, but decompose and yield hot combustion gases when heated and pressurized.

1958 C. C. Adams et al. Space Flight iii. 79 A monopropellant is generally unstable and delivers energy through its own decomposition, which is generally induced by a catalytic agent.

1972 Materials & Technol. IV. xix. 741 Hydrogen peroxide was employed as a monopropellant to provide power for the turbine-driven pumps [in the V2 rocket].

1987 Armed Forces June 255/2 A major drawback of many potential mono-propellants is their sensitivity to shock and to other potential ignition sources.

2000 New Scientist 6 May 42/3 As a rocket propellant it would double the power of the typical monopropellants that are used today.

B. adj.

Employing a monopropellant; of the nature of a monopropellant.
