Abstract : Two phenomena observed during plume diagnostic measurements acquired during simulated altitude chamber tests of aluminum-loaded solid-propellant rocket motors are discussed, and analytical results are presented. The results of a line-by-line calculation of the aluminum chloride (AlCl) feature are discussed and compared with high-resolution ultraviolet (UV) spectral data. Selected plume radiation measurements are reviewed, and evidence of searchlight emission is presented. Two searchlight modeling techniques are demonstrated and compared with motor test data.
