noun
- Plural of hypergol; substances that ignite spontaneously when mixed together, used as rocket propellants.
Usage: technical; aerospace
Examples
- The spacecraft used hypergols as fuel for its maneuvering thrusters.
- Hypergols are preferred for certain rocket engines because they ignite without an external ignition source.
- The chemical reaction between hypergols generates the thrust needed for orbital adjustments.
- Engineers must handle hypergols with extreme care due to their reactive nature.
