Book Synopsis Subsonic and Supersonic Flutter Analysis of a Highly Tapered Swept-wing Planform, Including Effects of Density Variation and Finite Wing Thickness, and Comparison with Experiments by : E. Carson Yates (Jr.)
Download or read book Subsonic and Supersonic Flutter Analysis of a Highly Tapered Swept-wing Planform, Including Effects of Density Variation and Finite Wing Thickness, and Comparison with Experiments written by E. Carson Yates (Jr.) and published by . This book was released on 1967 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flutter characteristics of several wings with an aspect-ratio of 4.0, a taper ratio of 0.2, and a quarter-chord sweepback of 45 deg. have been investigated analytically for Mach numbers up to 2.0. The calculations were based on the modified-strip-analysis method, the subsonic-kernel-function method, piston theory, and quasi-steady second-order theory. Results of t h e analysis and comparisons with experiment indicated that: (1) Flutter speeds were accurately predicted by the modified strip analysis, although accuracy at t h e highest Mach numbers required the use of nonlinear aerodynamic theory (which accounts for effects of wing thickness) for the calculation of the aerodynamic parameters. (2) An abrupt increase of flutter-speed coefficient with increasing Mach number, observed experimentally in the transonic range, was also indicated by the modified strip analysis. (3) In the low supersonic range for some densities, a discontinuous variation of flutter frequency with Mach number was indicated by the modified strip analysis. An abrupt change of frequency appeared experimentally in the transonic range. (4) Differences in flutter-speed-coefficient levels obtained from tests at low supersonic Mach numbers in two wind tunnels were also predicted by the modified strip analysis and were shown to be caused primarily by differences in mass ratio. (5) Flutter speeds calculated by the subsonic-kernel-function method were in good agreement with experiment and with the results of the modified strip analysis. (6) Flutter speed obtained from piston theory and from quasi-steady second-order theory were higher than experimental values by at least 38 percent.

Download or read book Yvain written by Chretien de Troyes and published by Yale University Press. This book was released on 1987-09-10 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.

Book excerpt: ‘KUMBA AFRICA’, is a compilation of African Short Stories written as fiction by Sampson Ejike Odum, nostalgically taking our memory back several thousands of years ago in Africa, reminding us about our past heritage. It digs deep into the traditional life style of the Africans of old, their beliefs, their leadership, their courage, their culture, their wars, their defeat and their victories long before the emergence of the white man on the soil of Africa. As a talented writer of rich resource and superior creativity, armed with in-depth knowledge of different cultures and traditions in Africa, the Author throws light on the rich cultural heritage of the people of Africa when civilization was yet unknown to the people. The book reminds the readers that the Africans of old kept their pride and still enjoyed their own lives. They celebrated victories when wars were won, enjoyed their New yam festivals and villages engaged themselves in seasonal wrestling contest etc; Early morning during harmattan season, they gathered firewood and made fire inside their small huts to hit up their bodies from the chilling cold of the harmattan. That was the Africa of old we will always remember. In Africa today, the story have changed. The people now enjoy civilized cultures made possible by the influence of the white man through his scientific and technological process. Yet there are some uncivilized places in Africa whose people haven’t tested or felt the impact of civilization. These people still maintain their ancient traditions and culture. In everything, we believe that days when people paraded barefooted in Africa to the swarmp to tap palm wine and fetch firewood from there farms are almost fading away. The huts are now gradually been replaced with houses built of blocks and beautiful roofs. Thanks to modern civilization. Donkeys and camels are no longer used for carrying heavy loads for merchants. They are now been replaced by heavy trucks and lorries. African traditional methods of healing are now been substituted by hospitals. In all these, I will always love and remember Africa, the home of my birth and must respect her cultures and traditions as an AFRICAN AUTHOR.
