Abstract
Reduced toxicity fuels containing hydrocarbons having both strained rings and internal, conjugated triple bonds are disclosed. The fuels described herein are hypergolic with nitrogen tetroxide and/or inhibited red fuming nitric acid.
Claims24
A fuel composition comprising a conventional fuel and a compound represented by the formula (I):
- wherein R1 and R2 are the same or different and represent an alkyl group having from 1 to 5 carbon atoms, provided at least one of R1 and R2 represents a cycloalkyl group having from 3 to 4 carbon atoms, wherein said fuel composition is hypergolic when brought into contact with an oxidizer selected from the group consisting of nitrogen tetroxide and inhibited red fuming nitric acid.
A propellant comprising a fuel composition and an oxidizer wherein said fuel composition comprises a compound represented by the formula (I):
- wherein R1 and R2 are the same or different and represent an alkyl group having from 1 to 5 carbon atoms, provided at least one of R1 and R2 represents a cycloalkyl group having from 3 to 4 carbon atoms and said oxidizer is selected from the group consisting of nitrogen tetroxide and inhibited red fuming nitric acid wherein the fuel composition is hypergolic with the oxidizer.
A method for producing a propellant comprising contacting a fuel with an oxidizer wherein said fuel comprises a compound represented by the formula (I):
- where R1 and R2 are the same or different and represent an alkyl group having from 1 to 5 carbon atoms, provided at least one of R1 and R2 represents a cycloalkyl group having from 3 to 4 carbon atoms and the oxidizer is selected from the group consisting of nitrogen tetroxide and inhibited red fuming nitric acid wherein the fuel is hypergolic with the oxidizer.
