S. Venugopalan et al., ROLE OF OXYGEN BALANCE ON THE THERMAL-DECOMPOSITION BEHAVIOR OF COMPOSITE PROPELLANTS, INDIAN JOURNAL OF ENGINEERING AND MATERIALS SCIENCES, 1, 1994, pp. 289-291
Differential thermal analysis (DTA) on amonium perchlorate (AP), hydro
xy terminated polybutadiene (HTPB) based polyurethane (PU) and other c
omposite propellant compositions consisting of AP and PU matrix has be
en studied. The data show that as the oxygen balance (OB) of the prope
llant composition decreases, the decomposition rate of AP during the s
econd stage (deflagration exotherm-Exo 11) around 360-degrees-C rises
very significantly due to the increase in calorific values.
