Download or read book Investigation of the Impact of Copper Filaments Into Aluminum Targets at Velocities to 16 000 Feet Per Second written by C. Robert Nysmith and published by . This book was released on 1964 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: One-half-inch- diameter aluminum spheres were fired into thin copper filaments (O. OO25inch diameter and O.75 inch length) at velocities to 16,000 feet per second, then recovered and sectioned to determine the damage. The principal variable was the filament angle of inclination. Microscopic examination of the sectioned targets and photographs revealed the various crater characteristics and penetration parameters for each shot. As the angle of inclination increased from O to 7, the depth of penetration decreased by a factor greater than 3 with most of the decrease occurring in the range from 4 to 5. Above 10 inclination angle, the penetration decreased more gradually to a final depth at broadside impact of approximately 1/10 that for end-on impact. The characteristic features of the craters also changed in these inclination ranges. Limited tests with filaments of 0.00l5-inch diameter showed a decrease in penetration approximately in proportion to the decrease in diameter. This result is very preliminary and may not be applicable to conditions other than those of this test. Incidental observations showed that small curvature of the filament may have a large effect on depth of penetration for end-on impacts but has essentially no effect for impacts of inclined filaments. The data are used to evaluate the probability of penetration greater than a selected depth for randomly oriented filaments.

Available in PDF, EPUB and Kindle. Book excerpt: This report is a guide to the literature on high-velocity metalworking. It consists primarily of abstracts of articles, reports, books, and current research projects on and related to high-velocity metalworking arranged according to technical subject. It covers a survey of the reported work in the field up to about October of 1962. Abstracts of over 700 references have been arranged by subject matter, with cross indexing between subjects. There is also an author index. The eleven major subjects and categories covered in the report are: (1) Energy Sources, (2) Energy Transfer Mediums, (3) Facility Requirements, (4) Tooling Requirements, (5) Equipment Requirements, (6) Forming, (7) Hardening, (8) Explosive Welding, (9) Powder Compaction, (10) Metal Removal, and (11) Material Behavior.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In the survey of high velocity impact information, a great deal of data was accumulated. Considerable difficulty was experienced in extracting original measured quantities, and originating laboratories were contacted whenever possible to supply tabulated data and additional information concerning material properties and measuring techniques. In some cases, such information was no longer available, and information was extracted from graphical data plots, and material properties corresponding to the material specifications were extracted from handbooks. The collected data are organized and presented under separate headings according to the projectiletarget configuration. (Author).

Book excerpt: The feasibility of a number of active shielding concepts against meteoroids is investigated. The effects of meteoroid flux on space vehicles and their components are first assessed, and the re quirements for passive (mass) shielding are cal culated. It is found that some active shielding concepts are practicable in the near term while others would require at least a ten year develop ment period. The most promising active shielding concept is the Dustwall, which can be developed in the near future. It is calculated that a dustwall system will weigh between 5% and 10% as much as passive shielding giving the same protec tion. In addition, it will protect components for which mass shielding cannot be used. (Author).
