Abstract : This study examined the problem of applying the dustwall for protection against meteoroid impact in the space environment. Results showed that dustwall systems are particularly suitable for such an application. Design parameters were obtained showing the containment of such systems to be feasible and practical. Design concepts of the containment systems are given. The following points summarize results of the work. Analysis of the dustwall-meteoroid interaction shows that two experimentally verified mechanisms, vaporization and cratering, each sufficient by itself to destroy the meteoroid, will act to destroy it. Design and analytical work on dustwall containment systems showed that two specific systems appear both feasible and practical for protection against meteoroids, containment based on mechanical circulation and the dustgas electrostatic containment. Specific component designs and dust flow data were obtained demonstrating the practicality and quantitative controllability of dust handling and charging technology. (Author)
