This book was released on 1987 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experimental investigation included the design and construction of a new, two-dimensional, rocket motor that could be used to obtain better holographic data than obtained in previous investigations using a small three-dimensional motor. The solid propellant used during this investigation was AP, HTPB, with 2%, 40 micron aluminum particles and 0.25% iron oxide. Good quality holograms were obtained using the three dimensional motor at operating pressures of 93 and 94 psia. Successful holographic recordings were also acquired using the new, two dimensional motor at pressures of 45 and 183 psia. System limitations and suggested improvements to the apparatus are discussed. Keywords: Holography; Metallized solid propellant combustion; Two dimensional rocket motor; Three dimensional rocket motor.

Book excerpt: An experimental investigation was performed to determine the feasibility of obtaining particle size data using pulsed-ruby holography in a three-dimensional metallized solid propellant rocket motor. Holograms of a USAF Resolution Target and a LEOS dot target were taken under various conditions, with the system resolution determined to be under 5 microns. Good quality holograms were obtained at pressures of 91, 110, and 280 psi using an HTPB/ammonium perchlorate propellant with 2 percent, 20 micron aluminum. Holograms were not successful at a pressure of 240 psi and 560 psi with a 2 percent aluminized AP/GAP propellant. For this propellant, transmittance tests indicated complete opacity during the steady-state portion of the burn.

This book was released on 1985 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted to determine the feasibility of obtaining holographic recordings of particulate behavior during the combustion process of solid propellant in a three-dimensional, windowed rocket motor. Transmittance measurements through the combustion chamber were made in order to select the appropriate neutral density filters which would yield the proper scene beam to reference beam intensity ratio. Holographic recordings were successfully made at combustion chamber pressures up to 185 psia using an HTPB-AP propellant containing 2.0 percent aluminum and 0.25 percent Fe203. The laser had to be fired manually because of the unreliability of the current igniter/grain design. For high combustion pressures, it is recommended that the laser beam power density be increased to penetrate the more opaque combustion products. Also, it is strongly recommended that a remote controlled laser firing device be used to improve the timing sequence for the hologram.

Available in PDF, EPUB and Kindle. Book excerpt: This investigation continued the development of a method for obtaining high quality holograms of the combustion products from aluminized solid rocket motor propellants burned in a two-dimensional motor to provide a cross-flow environment. The use of glass side plates as a motor casing provided both a convenient construction technique and allowed good quality holograms to be obtained. At combustion pressures above 500 psia and propellant slab thicknesses greater than 0.080 inches, the timing of the laser pulse during the burn was found to be critical, since an extremely short time interval existed between the establishment of steady state slab burning and the generation of too much smoke/combustion products to permit laser penetration. As desired operating pressures increase and aluminum powder particle sizes decrease, it will probably be necessary to use thinner propellant slabs. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The investigation completed the development process to establish a technique to obtain holographic recordings of particulate behavior during the combustion process of solid propellants in a two-dimensional rocket motor. Holographic and photographic recordings were taken in a crossflow environment using various compositions of metallized propellants. The reconstructed holograms are used to provide data on the behavior of aluminum/aluminum oxide particulates in a steady state combustion environment as a function of the initial aluminum size cast into the propellant. High speed, high resolution motion pictures were taken to compare the cinematic data with that available from the holograms. (Author).

This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * 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 activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Download or read book An Experimental Investigation of Strand Burning Metallized Solid Propellants written by and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characteristics of the products of combustion of metallized solid propellant strands at pressures between 250 and 750 psi were investigated using holography and light scattering measurements. In addition, scanning electron microscope and light scattering measurements were used to examine quenched residue. A reduced smoke ZrC propellant and three propellants of varying aluminum loading (2%, 4.8%, and 16%) were examined. The objective of the experiments was to provide to determine if any correlation of results from this method of analysis could be made with results from other more complex solid propellant motor measurements, such as plume probe and signature measurements. The results of these efforts reflected the inability of any single technique of analysis to completely describe particle size distributions. These results also suggest the need for modification of current experimental apparatus and procedures. (JES).

This book was released on 1987 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted pursuant to the development of a holographic technique to be used in the study of particulates in metallized solid fuel ramjet combustion. Additionally, a technique for generating a time-space dependent temperature profile of a two-dimensional solid fuel ramjet fuel slab was developed. A holocamera was designed and constructed for use with a two-dimensional solid fuel ramjet. Eleven micron resolution was obtained using diffuse illumination. Initial attempts to obtain holograms were unsuccessful. The fuels tested either would not sustain or, produced copious amounts of smoke which precluded a sufficiently intense scene beam from reaching the holographic plate. Use of 0.005 inch diameter, Chromel-Alumel thermocouples, imbedded at measured depths in the fuel slab, provided subsurface temperature data as a function of time and location, until exposed to free stream conditions. Keywords: Solid Fuel ramjet, Boron combustion, Metallized fuels ramjet, Holography.
