The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.

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 R.sub.1is a C.sub.1- to C.sub.6-alkyl radical or a C.sub.2- to C.sub.6-alkenyl radical, where R.sub.2 is hydrogen or a C.sub.1- to C.sub.6-alkyl radical or a C.sub.2- to C.sub.6-alkenyl radical, and where X.sub.1, X.sub.2 and X.sub.3 are each independently hydrogen, a C.sub.1- to C.sub.6-alkyl radical or a C.sub.2- to C.sub.6-alkenyl radical, and the oxidising agent comprises hydrogen peroxide.

A combustion tool fuel cell is provided having enhanced low temperature operation, including a fuel composition comprising at least one hydrocarbon component with a total vapor pressure equal or above 95 psig at 21° C.

A method for the degassing of hypergolic propellants includes introducing hypergolic propellant into a vacuum-tight vessel, cooling the vacuum-tight vessel containing the hypergolic propellant, and applying a pressure that is reduced as compared to the atmospheric pressure to the hypergolic propellant.
