Download or read book Aerodynamics of a Sphere and an Oblate Spheroid for Mach Numbers from 0 6 to 10 5 Including Some Effects of Test Conditions written by National Aeronautics and Space Administration NASA and published by . This book was released on 2018-10-23 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind-tunnel tests were made for spheres of various sizes over a range of Mach numbers and Reynolds numbers. The results indicated some conditions where the drag was affected by changes in the afterbody pressure due to a shock reflection from the tunnel wall. This effect disappeared when the Mach number was increased for a given sphere size or when the sphere size was decreased for a given Mach number. Drag measurements and Schlieren photographs are presented that show the possibility of obtaining inaccurate data when tests are made with a sphere too large for the test section size and Mach number. Tests were also made of an oblate spheroid. The results indicated a region at high Mach numbers where inherent positive static stability might occur with the oblate-face forward. The drag results are compared with those for a sphere as well as those for various other shapes. The drag results for the oblate spheroid and the sphere are also compared with some calculated results. Spearman, M. Leroy and Braswell, Dorothy O. Langley Research Center RTOP 505-69-20-01...

Download or read book Theoretical Analysis of the Flow Field Over a Family of Ogive Bodies written by Ronnie W.. Guy and published by . This book was released on 1977 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several analytical methods were employed to calculate the flow fields about spherically blunted ogives from Mach numbers of zero to 4.5. The methods used were the Dougles Herman (a panel method) with compressibility correction, the South potential flow program (RAXBOD) and the three dimensional method of characteristics. Bluntnesses varied from zero (sharp nosed) to one (hemispherical nose) and the finess ratio varied from 0.5 to 4.0. Where the computer codes being used permitted, the flow fields were calculated for 2 deg and 0 deg angle of attack; in all other cases only 0 deg angle of attack was considered. Data are presented for body surface distributions of pressure and Mach number and for wave drag. (Author).

Download or read book Effects of Wing and Tail Location on the Aerodynamic Characteristics of an Airplane for Mach Numbers from 0 25 To 4 63 written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-13 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigations have been conducted to determine the effect of wing vertical position and horizontal-tail vertical and axial position on the static aerodynamic characteristics of a wing-body horizontal-tail configuration. The configurations investigated included the wing in a high, mid, or low position on the body with the horizontal tail in each of these vertical positions as well as in three axial positions. The closest position of the horizontal tail to the wing essentially provided on all-wing configuration. In addition, tests were made for the three wing positions with the horizontal tail removed. The tests were made in three different wind tunnels to provide data for a Mach number range from 0.25 to 4.63. The purpose of the investigation was to illustrate the strong effects of interference flow fields as a function of geometry and flight regime. An analysis of the results indicate some arrangements that might lead to aerodynamic problems and others in which the interference flow fields might be favorably exploited. The results suggest that a coplanar concept with a translating horizontal tail could potentially minimize the aerodynamic changes with Mach number and provide more optimum performance over the Mach number range.

This book was released on 2018-06-30 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of the experimental and theoretical aerodynamic characteristics for some generic high-speed missile concepts at Mach numbers from 2 to 6.8. The basic body for this study had a length-to-diameter ratio of 10 with the forward half being a modified blunted ogive and the rear half being a cylinder. Modifications made to the basic body included the addition of an after body flare, the addition of highly swept cruciform wings and the addition of highly swept aft tails. The effects of some controls were also investigated with all-moving wing controls on the flared body and trailing-edge flap controls on the winged body. The results indicated that the addition of a flare, wings, or tails to the basic body all provided static longitudinal stability with varying amounts of increased axial force. The control arrangements were effective in producing increments of normal-force and pitching-moment at the lower Mach numbers. At the highest Mach number, the flap control on the winged body was ineffective in producing normal-force or pitching-moment but the all-moving wing control on the flared body, while losing pitch effectiveness, still provided normal-force increments. Calculated results obtained through the use of hypersonic impact theory were in generally good agreement with experiment at the higher Mach numbers but were not accurate at the lower Mach numbers.

Download or read book The Encyclopedia of Aerodynamics written by Frank Hitchens and published by Andrews UK Limited. This book was released on 2015-11-25 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Aerodynamics was written for pilots at all levels from private pilot to airline pilot, military pilots and students of aerodynamics as a complete reference manual to aerodynamic terminology. General aerodynamic text books for pilots are relatively limited in their scope while aerodynamic text books for engineering students involve complex calculus. The references in this book, The Encyclopedia of Aerodynamics, are clearly described and only basic algebra is used in a few references but is completely devoid of any calculus - an advantage to many readers. Over 1400 references are included with alternative terms used where appropriate and cross-referenced throughout. The text is illustrated with 178 photographs and 96 diagrams. The Encyclopedia of Aerodynamics is an ideal aerodynamic reference manual for any pilot's bookshelf.

Download or read book Marine Hydrodynamics 40th anniversary edition written by J. N. Newman and published by MIT Press. This book was released on 2018-01-26 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: A textbook that offers a unified treatment of the applications of hydrodynamics to marine problems. The applications of hydrodynamics to naval architecture and marine engineering expanded dramatically in the 1960s and 1970s. This classic textbook, originally published in 1977, filled the need for a single volume on the applications of hydrodynamics to marine problems. The book is solidly based on fundamentals, but it also guides the student to an understanding of engineering applications through its consideration of realistic configurations. The book takes a balanced approach between theory and empirics, providing the necessary theoretical background for an intelligent evaluation and application of empirical procedures. It also serves as an introduction to more specialized research methods. It unifies the seemingly diverse problems of marine hydrodynamics by examining them not as separate problems but as related applications of the general field of hydrodynamics. The book evolved from a first-year graduate course in MIT's Department of Ocean Engineering. A knowledge of advanced calculus is assumed. Students will find a previous introductory course in fluid dynamics helpful, but the book presents the necessary fundamentals in a self-contained manner. The 40th anniversary of this pioneering book offers a foreword by John Grue.
