Plume Contamination Effects Prediction: The CONTAM Computer Program. Program User's Manual

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 the 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). Analytical models and computer subprograms have been developed and integrated to form the CONTAM computer program. A sample case illustrating the CONTAM program's capability to predict contaminant production and transport is presented.
