STRAND SIZE AND LOW PRESSURE DEFLAGRATION LIMIT IN A COMPOSITE PROPELLANT

Abstract

The low pressure deflagration limit was determined for a composite ammonium chlorate propellant over a range of pressures from 35 torr to 235 torr. The independent variable was strand size in terms of cross-section dimensions. A linear relation was found between the 'hydraulic radius' of the strand and the low pressure limit. It was thus possible to extrapolate and determine the low pressure limit for a strand of infinite extent. At this limit it would seem that heat losses could only be by radiation from the surface.
