Abstract
In recent investigations at DLR Lampoldshausen a highly active catalytically promoted ionic liquid fuel with hydrogen peroxide was found. This fuel is based on an ionic liquid and a dissolved metal salt as catalytic promoter. But due to high viscosity of this fuel and bad mixing behaviour between hydrogen peroxide and fuel reliable ignition was not achieved. This investigation introduced different amounts of an organic solvent to the fuel and drop test were conducted to evaluate hypergolic performance. Repeatable ignition was achieved and the ignition delay times were around 28 ms.
