Holographic Investigation of Metallized Solid Propellant Combustion in a Three-Dimensional Motor

Abstract

An experimental investigation was performed to determine the feasibility of obtaining particle size data using pulsed-ruby holography in a three-dimensional metallized solid propellant rocket motor. Holograms of a USAF Resolution Target and a LEOS dot target were taken under various conditions, with the system resolution determined to be under 5 microns. Good quality holograms were obtained at pressures of 91, 110, and 280 psi using an HTPB/ammonium perchlorate propellant with 2 percent, 20 micron aluminum. Holograms were not successful at a pressure of 240 psi and 560 psi with a 2 percent aluminized AP/GAP propellant. For this propellant, transmittance tests indicated complete opacity during the steady-state portion of the burn.
