Analysis of the AlCl Absorption Feature and the Searchlight Emission Effect Observed in Solid-Propellant Rocket Plumes

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. AlCl absorption, plumes, solid-propellant rocket motor, searchlight, infrared, line-by-line calculation, plume radiation, ultraviolet, Monte Carlo.
