A statistical analysis was performed with use of Smithsonian Astrophysical Observatory's data on photographic meteors with use of weighting factors developed at Lewis Research Center for correction of various biases involved in meteor photography. The analysis used an armor damage criterion supplied by Ames Research Center. Although the analysis was restricted to Earth's orbit about Sun, implications are discussed regarding total population of meteoroids throughout the solar system. In Earth's orbit about the Sun, advantage was found for cylindrical armor extending in the solar direction and a plane sheet alined normal to apex of Earth movement.

Download Preliminary Investigation of Impact on Multiple-sheet Structures and an Evaluation of the Meteoroid Hazard to Space Vehicles Book in PDF, ePub and Kindle
Small pyrex glass spheres, representative of stoney meteoroids, were fired into 2024-T3 aluminum alclad multiple-sheet structures at velocities to 11,000 feet per second to evaluate the effectiveness of multisheet hull construction as a means of increasing the resistance of a spacecraft to meteoroid penetrations. The results of these tests indicate that increasing the number of sheets in a structure while keeping the total sheet thickness constant and increasing the spacing between sheets both tend to increase the penetration resistance of a structure of constant weight per unit area. In addition, filling the space between the sheets with a light filler material was found to substantially increase structure penetration resistance with a small increase in weight.

The meteoroid environment and the effects of hypervelocity impact on a space vehicles are described, and the effects of the incompleteness of present knowledge of each are discussed. The overall problem of the meteoroid hazard is evaluated and methods of eliminating the probability of meteoroid damage are given. A partial listing of typical research projects on meteoroid-environment and hypervelocity-impact problems is presented.
