An ambient drop test set-up was developed and used to obtain data about the hypergolic performance of TNO's novel hypergolic propellant combination. Said propellant combination was found to have an ignition delay time of 50 ms before further optimization, making it a promising candidate to replace the current toxic state-of-the-art hypergolic propellant combinations. Furthermore, based on the knowledge gained during the two ambient test campaigns a hermetic drop test set-up has been proposed and is under development.
