1. a single chemical substance that can be used as a propellant or fuel in rockets and spacecraft, decomposing or burning to produce thrust without requiring a separate oxidizer
Usage: technical; aerospace engineering

1. of, relating to, or using a single propellant substance
Usage: technical; aerospace engineering

Examples

• Hydrazine is a common monopropellant used in satellite thrusters.
• The spacecraft's monopropellant system requires careful handling due to the chemical's toxicity.
• Engineers selected a monopropellant engine for its simplicity and reliability.
• Monopropellant rockets decompose the fuel through a catalyst to generate thrust.
• The satellite uses monopropellant thrusters for attitude control and orbital adjustments.
