Diagnostic Measurements on an Aluminized Propellant Plume during Spin and Nonspin Testing.

摘要

Two identical aluminum-loaded solid-propellant rocket motors were tested at simulated altitudes of approximately 100,000 ft. One motor was fired under spin conditions, and the other was static-tested. Plume diagnostic measurements were made during the firings in the infrared to ultraviolet regions of the spectrum. Initial analysis of the data has been performed, and the results are summarized in this report. The data were analyzed with respect to radiant heating, searchlight emission, aluminum chloride absorption, spin effects, and particle mass distribution.
