Abstract
A hypergolic metal organic framework material for producing a hypergol when combined with an oxidizer, comprising a general structure M1-L-M2, wherein L is an aromatic organic linker comprising one or more unsaturated substituents, and wherein M1 and M2 are same or different metal cations.
Claims15
A propellant-generating combustible for producing a hypergolic propellant when combined with the oxidizer, comprising a hypergolic metal organic framework material for producing a hypergol when combined with an oxidizer, comprising a general structure M1-L-M2, wherein L is an organic linker comprising one or more unsaturated substituents, and wherein M1 and M2 are same or different metal cations, wherein M1 and M2 are each selected from:
- Co2+, Zn2+Cd2+, Fe2+, Ni2+ and Cu2+, and
- wherein said organic linker is an azolate linking moiety, and wherein the combustible has an ignition delay equal to or under 50 ms when combined with the oxidizer, resulting in the hypergolic propellant, with the proviso that the azolate linking moiety does not include a tetrazolate.
A hypergol comprising:
- a hypergolic metal organic framework material for producing a hypergol when combined with an oxidizer, comprising a general structure M1-L-M2, wherein L is an organic linker comprising one or more unsaturated substituents, and wherein M1 and M2 are same or different metal cations, wherein M1 and M2 are each selected from:
- Co2+, Zn2+Cd2+, Fe2+, Ni2+ and Cu2+, and wherein said organic linker is an azolate linking moiety;
- and the oxidizer, wherein an ignition occurs by combining said hypergolic metal organic framework material with the oxidizer, with the proviso that the azolate linking moiety does not include a tetrazolate.
