New family of hydrophobic ionic liquid rocket propellants could replace hydrazine-based fuels

New family of hydrophobic ionic liquid rocket propellants could replace hydrazine-based fuels 28 December 2015 Researchers in China have developed a family of hydrophobic borohydride-rich ionic liquids (ILs) which exhibit ultra-short ignition delay times as low as 1.7 milliseconds and the lowest viscosity (10 mPa·s) of hypergolic ionic liquids. The ILs thus show great potential as faster-igniting rocket fuels to replace toxic hydrazine derivatives in liquid bi-propellant systems. Hypergolic propellants ignite spontaneously when they comes into contact with each other. A paper on their work is published in the RSC journal Chemical Communications . Ionic liquids (salts with melting points below 100 °C) have been of interest for a number of years as possible replacements for hydrazine-based rocket fuels based on their attributes such as low volatility. In a discussion of an e...
