Process for Assessing the Stability of HAN (Hydroxylamine)-Based Liquid Propellants.

Abstract

The first intermediate report covers the selection of work materials and the subsequent treatment of work materials for the pressure sensors. During storage of the monergols containig HAN at higher temperature (90 deg C) hydroxylamine and nitric acid are produced apart from water vapor in the gas phase of the pressure container. The presence of these substances can be demonstrated in the distillate of LP 1846. Consequently, they are also capable of reacting with the work material of the pressure sensors and contaminating the sample during long-term storage of the liquid propellants. Keywords: Liquid Propellants, Monergols; Chemical stability, Long term stability.
