Mass Spectroscopic Observation of Ignition Phenomena in a Small Rocket Combustion Chamber

Abstract

Observations of small rocket firings were examined for evidence of ignition phenomena. Qualitative analysis of product gas composition was made through molecular beam sampling from the combustor wall and direct mass spectrometer analysis. The combustion of hydrazine/nitrogen tetroxide and of hydrazine/chlorine pentafluoride were observed. The technique allows following the sequence of species present in the chamber during the ignition phase. Time resolution was limited by data recording techniques to 22 msec.
