Claim 0:
1. A hypergolic two-component system for rocket engines, including a fuel and an oxidising agent that are provided in a manner separated from one another and can be reacted in a rocket engine by bringing them into contact with one another, wherein:
the fuel is an ionic liquid comprising a thiocyanate anion and one or more cations, wherein 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 R1 is a C1- to C6-alkyl radical or a C2- to C6-alkenyl radical,
where R2 is hydrogen or a C1- to C6-alkyl radical or a C2- to C6-alkenyl radical, and
where X1, X2 and X3 are each independently hydrogen, a C1- to C6-alkyl radical or a C2- to C6-alkenyl radical; and wherein:
the oxidising agent comprises hydrogen peroxide,
the fuel comprises one or more additives for the purpose of shortening the ignition delay when it is brought into contact with the oxidising agent, with a proportion of up to 30 weight %, and
the additive or additives are catalytic additives that are selected from thiocyanates of transition metals.
