HYPERGOLIC IGNITION AT REDUCED PRESSURES

Abstract

The report covers the first five months of a ten-month experimental investigation of the ignition of hypergolic propellants at reduced pressures. Unconfined impingement tests are being conducted in a large vacuum chamber in order to define an ignition model for hypergolic propellants and to investigate concepts for reducing ignition delay and resultant pressure spikes. The test setup, experimental program schedule, and concepts for reducing ignition delay are discussed. Results are reported on ignition delay as a function of injection parameters, environmental conditions and concepts such as injector modifications and propellant additives for reducing delay for tests performed with N2O4 and IRFNA as oxidizers and hydrazine-type fuels.
