Combustion Studies of Very High Burning Rate (VHBR) Propellants

Abstract

The burning and impetus characteristics of a family of very high burning rate (VHBR) boron-hydride-based propellants were determined using the closed chamber technique. A systematic examination of burning behaviour vs chemical composition was made. The samples studied included bare, steel cased, and larger full bore cylindrical samples. Pressure time data were reduced to apparent linear burning rates using the conventional laminar burning assumptions made in closed chamber reductions. The results indicate that tailoring sample burning rates between 1 and 500 m/s may be possible. On the other hand, unlike conventional propellants, VHBR propellant burning rates are thought to depend not only on sample formulation but also on porosity, physical integrity, sample diameter, and confinement. These results point to a possible burning-with- breakup mechanism for these materials.
