Contamination Measurements During the First Vacuum Test of the Large IUS Solid Propellant Motor.
Abstract
The plume contamination monitoring experiment of the IUS motor test conducted 19 December 1977 at AEDC consisted of several specimen witness plates that were placed in four sample canisters located around the rocket motor plume boundary. In this report are described the contamination sampling methods and the analytical results obtained from the plume sampling of the IUS motor test. Recommendations for future contamination monitoring of IUS tests are also given. There is a potential contamination problem from the IUS firings as submicrometer to several tens of micrometer diameter particles were found on the specimen witness plates. The shape and composition of the particles varied widely but were mainly spherical in shape containing carbon, aluminum, or silicon. A molecular film was also present on many of the witness plates.
