Available in PDF, EPUB and Kindle. Book excerpt: The NATO Research and Technology Organization (RTO), Advanced Vehicle Technology (AVI), Working Group (WG) 016 (formerly AGARD/PEP Working Group (27) undertook to evaluate methods in use within the NATO propulsion community to measure burning rate in solid propellant rocket systems, with the purpose of identifying similarities and differences between the participating nations. This WG was formed in 1996, consisting of active representatives from 6 of the 15 member nations of NATO, with inputs accepted from 4 other member nations and a couple non-member nations. The NATO RTO/AVT WG 016 sought to contribute to improvements in the burning rate tools to address issues that have plagued the solid propulsion industry for over 40 years. This paper reviews the final results of this study by summarizing the objectives, approach, findings, and recommendations of this working group based on activity from October 1997 to March 2001. Recommendations are reviewed on direct and non-intrusive burning rate measurement methods, data analysis, and performance scaling to support improved prediction of internal ballistics of a full-scale solid propellant motor. AVT WG 016 activities have identified that manufacturer burning rate data may not easily be compared without accounting for industry-wide differences in subscale devices, test methods and scaling analysis methods. The WG recommends the NATO propulsion community review these findings as a means of advancing their own burning rate measurement and analysis methods.

Available in PDF, EPUB and Kindle. Book excerpt: Experiments show that the burning rate of solid propellants is a function of the pressure under which the burning takes place. An often used method to determine that burning rate function is to burn a sample of the propellant in a closed container and to register the corresponding pressure-time data. With the aid of formulas from thermodynamic theory these observations can be manipulated to yield the desired parameters of the burning rate function. This analysis is typically done under a number of restrictive assumptions, e.g., the assumption of constant temperature in the container throughout the experiment. In spite of such assumptions the corresponding algorithms published are complicated and an error analysis of the results has apparently never been reported. In the present paper new formulas are derived under relaxed assumptions. With the aid of these formulas the data analysis is reduced to a curve fitting task. For such tasks standard theories and computer programs are available, which furnish the unknown parameters of the burning rate function together with estimates of their variances and co-variances. The new formulas can be replaced by simpler ones under conditions, which are controllable by the design of the experiment. It is found that for such simplifications the temperature's behavior is not relevant. In general the simplifications are permissible if the maximum pressure achieved during the experiment remains essentially smaller than the chemical energy released per unit volume of the propellant. The latter is typically of the order of 10 to 10th power Pa (10 to 5th power). An example illustrates the application of the new algorithm.

This book was released on 2001 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current burning rate measurement test techniques and subscale test hardware used within the NATO community are reviewed and recommendations are made to support improved prediction of internal ballistics of a full-scale solid propellant motor. The NATO Research and Technology Organization (RTO), Advanced Vehicle Technology (AVT), Working Group (WG) 016 (formerly AGARD/PEP Working Group #27) undertook to evaluate methods used within the NATO propulsion community to measure burning rate in solid propellant rocket systems. The purpose was to identify similarities and differences among the member nations. The WG 016 sought to contribute to improvements in the burning rate tools by addressing issues that have remained unresolved in the solid propulsion industry for over 40 years: (1) Better understanding of burning rate, r(beta)(p, T(omega), data from various facilities to ease the comparison of propellants from various manufacturers and to improve international exchanges and cooperation. (2) Improved measurement accuracy and reliability to allow a decrease in the number of tests (and associated time and cost) and improved control of manufacturing and quality assurance and the assessment of aging. AVT WG 016 activities have identified that manufacturer burning rate data may not easily be compared without accounting for industry-wide differences in subscale devices, test methods and scaling analysis methods. The WG recommends the NATO propulsion community review these findings as a means of advancing their own burning rate measurement and analysis methods.

Book Synopsis An Improved Method for the Measurement of Solid Propellant Strand-burning Rates in Closed Bombs by : D. H. Stewart

This book was released on 1963 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new method for determining propelland strand burning rates without the use of timing wires has been developed. It was found that when the cross-sectional area of the strand is sharply varied at known intervals, the burning rate can be obtained from assessment of the resulting pressure-time trace. Results of the new method are within 1% of the standard wire technique. The method is applicable to ''difficult'' propellant systems and offers advantages of lower cost, higher reliability, and safety. (Author).

This book was released on 1972 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instantaneous burning rate data for a polybutadiene acrylic acid propellant, containing 16 weight percent aluminum, were calculated from the pressure histories of a test motor with 96.77 sq cm of burning area and a 5.08-cm-thick propellant web. Additional acceleration tests were conducted with reduced propellant web thicknesses of 3.81, 2.54, and 1.27 cm. The metallic residue collected from the various web thickness tests was characterized by weight and shape and correlated with the instantaneous burning rate measurements. Rapid depressurization extinction tests were conducted in order that surface pitting characteristics due to localized increased burning rate could be correlated with the residue analysis and the instantaneous burning rate data. The acceleration-induced burning rate augmentation was strongly dependent on propellant distance burned, or burning time, and thus was transient in nature. The results from the extinction tests and the residue analyses indicate that the transient rate augmentation was highly dependent on local enhancement of the combustion zone heat feedback to the surface by the growth of molten residue particles on or just above the burning surface. The size, shape, and number density of molten residue particles, rather than the total residue weight, determined the acceleration-induced burning rate augmentation.
