STUDY OF THE PARTICULATE MATTER IN THE EXHAUST OF A BORON-LOADED SOLID PROPELLANT.
Abstract
Particles issuing from the primary solid propellant combustor of a typical boron-loaded air-augmented rocket motor have been collected and analyzed for chemical composition and size distribution. It was found that substantial changes can occur in the chemical composition of the particulate effluent (notably, ammonium pentaborate and carbon were found), but the size analyses suggest that no important change in the boron size distribution occurs. However, this last conclusion is subject to the uncertainties involved in any particle collection technique's influence on the size distribution results, and for this reason a discussion of possible in situ measurements using light scattering is included at the end of this report. Primarily because of the high optical depths involved in the primary motor plume, however, it is concluded that such experimental techniques would be unsuccessful. (Author)
