This book was released on 1966 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report evaluates twenty-two ablative-material samples as nozzle sections of a storable-propellant (nitrogen textroxide and a 50-50 percent blend of unsymmetrical dimethylhydrazine with hydrazine) rocket engine to determine general trends among the material variables and to enable comparison of such trends with those observed from similar tests with a hydrogen-oxygen rocket engine reported in NASA TN D-3258.

Available in PDF, EPUB and Kindle. Book excerpt: The development of new and superior materials for rockets and missiles is one of the most important phases of the current space program. Such development requires extensive testing under conditions that simulate actual exposure as closely as possible. A few hundred degrees difference in gas temperature, a change in gas velocity, or in chemical composition can markedly alter the resistance that a material might exhibit to a particular ablative condition. The conditions surrounding a particular missile material are generally very "unusual," that is, temperatures of 5000 F or more, gas velocities of Mach 10 or higher, highly oxidizing atmospheres, and other equally difficult conditions. Previous attempts to duplicate these "unusual" conditions in the laboratory have resulted in such expensive and space-consuming apparatus as wind tunnels, shock tubes, and complete test rocket motors. To overcome the cost, space, and power problems and to help speed up materials research and the flow of new materials to the missile industry, the Aerojet-General Corp. began a program to determine whether simple, inexpensive equipment could be developed or designed to give meaningful test results. With such equipment, it was hoped that new and superior materials would be developed at a substantially faster rate than at present.

Download or read book Measurement of Rocket Nozzle Surface Recession Using Spectrographic Techniques written by Wendell A. Stephen and published by . This book was released on 1972 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this program was to design, analyze, and evaluate experimentally the surface recession of ablative materials using spectrographic techniques. This program was accomplished in two phases. The first phase was the design, analysis, and development of a containment system for the tracer elements. The second phase was the demonstration of the feasibility of that system during static firings in two rocket nozzles, one fabricated from carbon-phenolic and the other from silica-phenolic with a codeposited silicon carbide/pyrolytic- graphite throat insert. Laboratory tests were conducted with a plasma-arc torch to verify the capsule design. The capsules, with thermocouples, were then tested in a solid rocket motor at a pressure of 800 psi with 16%-aluminized polybutadiene-acrylic acid-acrylonitrile propellant. The test results showed poor correlation between the ablation as indicated by thermocouples and that indicated by detection of the tracer salts. This report describes the various program activities from initial tracer selection and configuration selection to final test firing demonstration and analysis of test results. (Author-PL).
