Book excerpt: The problem of determining performance levels of supersonic/hypersonic combustion inlet models is presented. Previous approaches to this problem are discussed and g40thod involving force balance determination of the internal drag is proposed. Results of a computational procedure formulated for calculating inlet performance levels from measured internal drag values are presented. Effects of chemical reactions and exit flow profile nonuniformity are accounted for. Levels of anticipated accuracy, using this technique, are adequate for present applications over a Mach Number range of 8 to 25. (Author).
Book Synopsis Preliminary Weight Estimates for Advanced Dynamic Energy Conversion Systems by : George D. Huffman
Download or read book Preliminary Weight Estimates for Advanced Dynamic Energy Conversion Systems written by George D. Huffman and published by . This book was released on 1963 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: An assessment of working fluids for use in a high-temperature dynamic power conversion system is presented. The method of comparison of the various fluids consists of a preliminary design of the major system components. The results are presented as conversion system weights for the considered fluids, potassium, sodium, lithium, bismuth, and lead, at various values of turbine inlet temperatures. On the basis of the generated data, it has been concluded that only potassium and sodium are practical for use as a working fluid in the temperature range of consideration, 2000 to 4000 R. It is further concluded that potassium and sodium at turbine inlet temperatures from 2800 to 3200 R offer systems of sufficiently low weight to warrant further and more detailed investigations.

Book excerpt: The use of liquid alkali metals as a heat transfer medium or motive fluid for power conversion systems has increased significantly in recent years and has created new demands in the area of liquid alkali metal handling technology. Contaminants existing in liquid alkali metal systems may exert deleterious effects on thermophysical properties, corrosivity and handlin characteristics. This paper presents an analytical study on the physicochemical and kinetic aspects of liquid cesium purification, employing the hot gettering technique. The properties and various aspects of handling sodium, potassium, rubidium and cesium are reviewed. Typical sources of contamination are discussed. (Author).
Book Synopsis Progress in Aeronautical Sciences by : D. Küchemann
Download or read book Progress in Aeronautical Sciences written by D. Küchemann and published by Elsevier. This book was released on 2016-07-02 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Aeronautical Sciences, Volume 8 is a collection of papers that covers the widening field of aeronautical sciences. The first article deals with problems in fluid mechanics and practical aerodynamics. This paper includes reducing problems to integral equations; the comparison of calculated results with exact analytic solutions; and with experimental pressure distributions using various configurations. The book follows this discussion with a review of the methods for designing swept-winged aircraft, including the design of a symmetrical-fuselage combination at zero incidence. The text also reviews the propulsion characteristics of a hypothetical aircraft flying at hypersonic speeds, and then focuses on air-breathing engines to power hypersonic aircrafts of which the scramjet is the most promising. The publication renders a comprehensive report on the viscous flow in boundary layers in ducts under rarefied conditions. The book then reviews investigations made on the viscous flow through tubes, both in continuum flow and in free-molecule flow. Another paper develops the fundamental mathematical and physical bases of magnetohydrodynamic flow through ducts in the presence of an applied electromagnetic field. Such review is useful when applied to electromagnetic flowmeters, pumps, or generators. The volume can be helpful for aerodynamic researchers, aviation technologists and designers, and aeronautical engineers.

Book Synopsis System Components Information Center by : Marvin G. Toll
Download or read book System Components Information Center written by Marvin G. Toll and published by . This book was released on 1963 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a proposed information transfer program for the selection and approval of components used in Air Force systems. It is intended for use by designers and also by the management group approving what the designers recommend. A method is presented showing how technical characteristics are used as the basis for item selection. When a complete characteristic description is determined, an established index code substitutes numbers for the particular words thus permitting rapid machine search and retrieval. The program employs 1000-ft microfilm facilities for storage and retrieval. It features technical summaries of engineering data as the output for quick determination as to whether the selected items satisfy the requirement.

Book Synopsis Ring Laser Techniques for Angular Rotation Sensing by : D. A. Guidice
Download or read book Ring Laser Techniques for Angular Rotation Sensing written by D. A. Guidice and published by . This book was released on 1963 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of using a ''ring'' laser to measure angular rotation is presented. The optical frequencies of the clockwise and the counterclockwise beams traveling around the perimeter of the square ''ring'' depend on their respective optical path lengths which are equal in the absence of rotation. However, angular rotation alters the path lengths, resulting in different frequencies for the two traveling waves. The two waves are optically heterodyned in a photodetector and the resultant beat frequency is directly proportional to the rotation rate of the ''ring.'' An experiment verifying the existence of this phenomenon using a gas laser in the square ''ring'' configuration is described. The physics of mode pulling and various ways to minimize or bypass this problem are discussed in detail. Techniques for artificially separating the frequencies of the two waves by introduction of nonreciprocal elements into the optical path are described. Accuracy limitations caused by mechanical instabilities, excitation variations and inherent stimulated emission line width are examined.

Book Synopsis Transonic Off-design Drag and Performance of an Axisymmetric Inlet with 40 Percent Internal Contraction on Design by : Richard R. Woollett
Download or read book Transonic Off-design Drag and Performance of an Axisymmetric Inlet with 40 Percent Internal Contraction on Design written by Richard R. Woollett and published by . This book was released on 1974 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation determined the drag and pressure performance of an axisymmetric supersonic inlet when operated in the transonic speed range. The inlet configuration was derived from a Mach 2.5 mixed compression inlet design with assumed variable geometry. At typical engine airflows the drag coefficient varied from 0.057 to 0.192 when the Mach number changed from 0.80 to 1.27. The presence of a wing simulator resulted in a sizable increase in total drag at Mach 1.2. This interference drag, which is roughly a 0.1 increase in drag coefficient, originates equally from an increase in both additive and cowl pressure drag.

This book was released on 1968 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a test program to determine the drag of supersonic inlets operating at transonic Mach number conditions. It is a supplement to Air Force Report AFAPL-TR-68-119 describing the results of additional tests conducted under Air Force Contract F33615-68-C-1520. Data are presented showing the additive drag and total inlet drag of the F-4 aircraft inlet measured in the presence of the aircraft forebody and in an undisturbed stream. Inlet drag test data are also presented for a series of thirteen configurations where the sideplate geometry is the primary variable. All thirteen configurations are variations on a single two-dimensional inlet. Tests to reproduce some of the data reported in AFAPL-TR-68-119 were conducted to evaluate the accuracy of the experimental procedure. (Author).
