At present, there is considerable interest in supercritical wing technology for the development of aircraft designed to fly near the speed of sound. The basic principle is the suppression of boundary layer separation by shifting the shock waves that occur on the wing toward the trailing edge and making them as weak as possible. The purpose of this report is to make available to the engineering public mathematical methods for the design of supercritical wings. These methods depend on the numerical solution of the partial differential equations of two-dimensional gas dynamics. The main contribution is a computer program for the design of shockless transonic airfoils using the hodograph transformation and analytic continuation into the complex domain. Another contribution is a program for the analysis of transonic flow with shocks past an airfoil at off-design conditions. In our design work we include a turbulent boundary layer correction. Part I of the paper is devoted to a description of the mathemati- cal theory and need not be studied by those primarily concerned with running the programs. Part II is a manual for users of our programs which is independent of the theoretical part. In Part III and in Appendices II and III we give numerical examples and discuss computa- tional results. The main substance of the report, however, is contained in the listing of the computer programs themselves in Appendix IV. We have used the Fortran language throughout and we have included numerous comment cards in the listing.

Your little one will love to discover the amazing animals inside this bright board book. There are 100 animal photographs to look at and talk about, and 100 animal names to read and learn, too. The pages are made from tough board for hours of fun reading, and the cover is softly padded for little hands to hold. As unrest stirs across the Eleven domains, subversive questions lead to unexpected answers. And ghosts of the dead walk in increasing numbers - A Theory of Supercritical Wing Sections, with Computer Programs and Examples : With Computer Programs and Examples download ebook pdf for those few that can see. In a land where stonecasters foretell destinies for a fee and gods talk to those who can listen, the future is uncertain and is built on a bloodsoaked past. So what did happen one thousand years ago, when Acton's people came across the mountains? Was Acton himself a hero and liberator, or a bloodthirsty invader and scourge of the travelling people? Wild magic gives Bramble some dangerous insights into a land's disturbed history. And why did Ash's Traveller father not teach him the secret songs of his people? The ultimate answers to all these questions are hidden in time, where perhaps they should stay.
