Available in PDF, EPUB and Kindle. Book excerpt: Internal chamber areas of solid propellant rocket motors are lined with ablative insulation to block the transfer of heat to temperature sensitive case materials. The heat rates to ablative insulators can not be determined by conventional means such as staggering thermocouples through the wall because no workable analytical solution exists for the ablative model. Therefore, it was necessary to measure the heat rates directly by mounting transducers in the ablative wall. A small 5-inch diameter rocket motor was used as the test vehicle for this study, and ablative materials were mounted in the blast tube or in the chamber (peripheral slab) area. Peripheral slabs were subjected to low velocity gas flow calculated to be 50 ft/sec; low velocity flow prevents erosion from affecting the operation of the calorimeters. Because the blast tube has an initial calculated velocity of 870 ft/sec and is therefore subject to extensive erosion, no serious attempt was made to design a heat flux gage for this area. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to develop techniques for obtaining quantitative data that can be used to relate solid rocket propellant composition and operating environment to the behavior of solid particulates within the grain port and exhaust nozzle. The techniques employed are high speed motion pictures of propellant strand burners and slab burners in a cross-flow environment, SEM analysis of post-fire residue (strand, slab, and motor), determination of D32 across the exhaust nozzle using measurements of scattered laser light, and holograms of burning propellant strands, slabs, and motors. In addition, techniques are being developed for automatic retrieval of particular size distributions from holograms taken of the combustion of solid propellants. Results are presented on (1) the measurement of particular size changes across an exhaust nozzle, (2) holograms obtained at the nozzle entrance, and (3) automatic data retrieval from holograms. Keywords: Solid propellants, Particular sizing, Holograms, Particulates, Optical methods, Speckel reduction.

This book was released on 1986 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine the feasibility of introducing particles of a known mean diameter into a small solid propellant rocket motor and measuring the change in mean diameter across the exhaust nozzle. Light scattering profiles at small forward angles were recorded at the entrance and exit of the nozzle. The propellant used was nonmetallized and contained HYPB and ammonium perchlorate. Promising results were obtained for injections of polydispersions of glass beads and aluminum oxide particles.

This book was released on 1982 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this initial investigation was to develop and compare experimental techniques that could be used for obtaining quantitative data on the effects of propellant properties, operating pressure and nozzle geometry on the behavior of metallized particulates within the grain port and nozzle of solid propellant rocket motors. The techniques employed were high speed motion pictures of strand burners and slab burners in a cross-flow environment, SEM analysis of post-fire residue (strand, slab, and motor), determination of D32 at the exit of an exhaust nozzle using measurements of scattered laser power spectra, and holograms of burning propellant strands and slabs in a cross-flow environment. All techniques were successfully developed and employed to obtain particulate size data from a series of specially formulated propellants. The motion picture and holographic techniques were successfully demonstrated for operating pressures of 34 and 68 atm. and with up to 15% aluminum. Fourteen micrometer resolution was obtained in the high speed motion pictures with a 1. 12X magnification (and very small depth of field) and eleven micrometer resolution was obtained in the holograms. Measurements of D32 at the nozzle exit plane of a small end-burning motor were in close agreement with size analysis of collected exhaust particulates.
