Abstract : An investigation was conducted pursuant to the development of a holographic technique to be used in the study of particulates in metallized solid fuel ramjet combustion. Additionally, a technique for generating a time-space dependent temperature profile of a two-dimensional solid fuel ramjet fuel slab was developed. A holocamera was designed and constructed for use with a two-dimensional solid fuel ramjet. Eleven micron resolution was obtained using diffuse illumination. Initial attempts to obtain holograms were unsuccessful. The fuels tested either would not sustain or, produced copious amounts of smoke which precluded a sufficiently intense scene beam from reaching the holographic plate. Use of 0.005 inch diameter, Chromel-Alumel thermocouples, imbedded at measured depths in the fuel slab, provided subsurface temperature data as a function of time and location, until exposed to free stream conditions. Keywords: Solid Fuel ramjet, Boron combustion, Metallized fuels ramjet, Holography.
