Abstract
The present invention relates to a hypergolic two-component system for rocket engines, including a fuel and an oxidising agent provided in a manner separated from one another and can be reacted in a rocket engine by bringing them into contact with one another. The fuel is an ionic liquid comprising a thiocyanate anion and one or more cations. The cation or cations are selected from one or more imidazolium ions of the general formula I, triazolium ions of the general formula II or III, and/or tetrazolium ions of the general formula IV, where Ris a C- to C-alkyl radical or a C- to C-alkenyl radical, where Ris hydrogen or a C- to C-alkyl radical or a C- to C-alkenyl radical, and where X, Xand Xare each independently hydrogen, a C- to C-alkyl radical or a C- to C-alkenyl radical, and the oxidising agent comprises hydrogen peroxide.
