Abstract:

An investigation was made of the heat-up, ignition and combustion of a nitrate ester monopropellant droplet when suddenly placed in a high temperature gas. At moderate pressures a combustion zone became noticeably developed as the droplet approached its wet bulb temperature and a steady burning period followed. At high pressures reactive effects became noticeable early in the heat-up period and burning was not steady. In this regime the droplet spent most of its lifetime in the preignition period. A heat-up theory of ignition is developed and found to be in agreement with the moderate pressure data. Burning rates also are reported over the test range.
