noun
- a fuel or oxidizer that ignites spontaneously when mixed with another hypergolic substance, used in rocket propulsion systems.
Usage: technical; aerospace
Examples
- The spacecraft uses hypergol propellants that ignite on contact without requiring an external ignition source.
- Hydrazine is a common hypergol used in satellite thrusters.
- The advantage of hypergol systems is their reliability in the vacuum of space.
- Engineers selected hypergol fuel for the mission because it performs well in extreme temperatures.
- The rocket's engine relies on a hypergol combination to achieve rapid thrust.
