The salts, when added as trigger additive to combustible solvent or ionic liquids, make the resulting formulation hypergolic. The salts with borane cluster anions also shorten ignition delay in hypergols, such as RP-1, and additionally allow nitric acid to be used to replace liquid oxygen as an oxidizer. In some examples, the borane salts are formed in situ in an ionic liquid. | 12-25-2014 |
