1947 Jrnl. Brit. Interplanetary Soc. 6 104 Fuels are broadly classified in three groups, monergols, hypergols and non-hypergols.

1947 Jrnl. Brit. Interplanetary Soc. 6 105 The distinct property of hypergols is that the reaction is self-starting.

1950 Sci. News 15 77 One class [of propellants], called hypergols, react as soon as they come together... Such pairs are..hydrazine hydrate and hydrogen peroxide.

1969 R. T. Holzmann Chem. Rockets ii. 140 The use of hypergols is both simple and safe.

Derivatives

hyperˈgolic adj. igniting spontaneously on contact with the oxidant or another propellant; also as n., a hypergol.
