Abstract:

The effect of rocket exhaust plume impingement on sensitive vehicle surfaces is an area of continuing concern in the design of spacecraft, missiles and reentry vehicle systems. The objective of this study was to develop a single computer code capable of predicting the production, transport, and deposition of engine and plume contaminants, and the change in absorptivity, emissivity, reflectivity, and transmissivity of a functional spacecraft surface, such as thermal control coatings and optical view ports and lenses, resulting from plume contaminant deposition or mechanical abrasion sand blasting. Both bipropellants and monopropellants have been treated. Surface chemical reaction with a deposited plume contaminant layer was not treated. Analytical models and computer subprograms have been developed and integrated to form the CONTAM computer program. Complete users manuals for each of the computer subprograms as well as the CONTAM program are included in this report, along with details of the analysis and numerical methods. A sample case illustrating the CONTAM programs capability is presented.
