Available in PDF, EPUB and Kindle. Book excerpt: Catastrophic failure of a partially filled aircraft fuel cell due to impact and penetration by a high speed projectile often occurs due to a phenomenon known as hydraulic ram. The structural response of the fuel tank walls to hydraulic ram should be of vital concern to the designers of aircraft fuel cells. Considerable research has been conducted to determine the effects of hydraulic ram on metallic fuel cells, but very little attention has been given to fuel cells made with the new advanced composite materials. The purpose of this research is to examine the various effects of hydraulic ram on a graphite/epoxy wall when subjected to penetration by a .222 caliber projectile. Eight hydraulic ram tests are made on a clamped 11-inch square plate 0.067 inches thick at projectile velocities between 2600 and 2800 fps. The engineering properties of the laminate are determined both analytically and experimentally. The low velocity shots caused only slight damage to the plate. At the higher velocities, the hydraulic ram caused considerable damage, including total serverance of the plate from its clamped support over much of the outer perimeter. The results of this research illustrate the importance of the method of attachment of the composite wall at its boundaries. (Author).

This book was released on 2013-11-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.
Download or read book Fuel Cell Entry Wall Response to Hydraulic Ram written by Bruce Dean Page and published by . This book was released on 1975 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic ram concerns the dynamic loads and catastrophic failure of liquid-filled fuel tanks impacted by high speed projectiles. Hydraulic ram is divided into two phases: the shock phase and the drag phase. Analytical models have been proposed for the shock phase pressures by Yurkovich and for the drag phase pressures by Lundstrom. Comparisons were made between hydraulic ram fuel cell entry wall strains predicted using several loading models and those determined experimentally. A reasonable correlation was achieved but more work must be done to permit predictions of hydraulic ram strains accurate enough for the purpose of fuel cell design.
