Solid Rocket and Space Propulsion Studies.
Abstract
This research was concerned with four rocket related topics: forced longitudinal wave mortors, nonsteady burning in randomly layered media, insitu burning rate measurements, and thermal protection systems for radiant energy deposition powered thrustors. Apparatus for the forced longitudinal wave motor procured from Princeton, a test cell was readied and pressure instrumentation purchased. In addition, preliminary theoretical and flow visualization studies were conducted. The latter showed the following: (1) when port Mach number is not small, both response and admittance functions enter as unknowns, and (2) port and near burning surface flows are not in phase so that periodically inflected velocity profiles accompany axial mode oscillations. Nonsteady burning studies showed that extinguishments can occur in fine particle psuedo propellant to course propellant psuedo propellant transitions and that the constant pressure burning rate auto-spectra contains resonance at the layer frequencies, twice layer frequencies, and characteristic frequencies; previous models assumed resonances solely at the layer frequencies.
