Overview Modern sailplanes are among the most beautiful and efficient aircraft ever built. The competitive demands of the sport of soaring have led to graceful, highly optimized sailplanes with glide ratios approaching From the beginning, much of the progress in sailplane design has been due to the work of the German Akafliegs. In its original German, it served as a textbook for an introductory course in sailplane design and a valuable reference for students in the Akafliegs.
This English edition has been expanded and updated to include many sailplanes and technical developments that have appeared since the latest German edition. However, this book is not only for the designer - it is also intended for sailplane pilots who wish to better understand the aircraft they fly.
The discussion is kept at an introductory level, with emphasis on visualization and understanding the physical relationships rather than mathematical detail. Experienced engineers will appreciate this text as well. The book contains an outstanding collection of detailed information on sailplane design, including discussions of sailplane airfoils, certification regulations and sailplane flight testing, an extensive bibliography, and an appendix with design data for over sailplanes.

Such a glider should have outstanding straight line and thermaling performance, good handling qualities, and a comfortable cockpit. The pilot may also want an engine since outlanding a 28 to 31 meter span ship can often get very interesting as well as putting himself and his placing in the competition at risk. Unfortunately each of these criteria is normally compromised in the end when designing a sailplane for production or, to put it more directly, when the business side of the equation is considered. The market for a pure open class competition sailplane is relatively small for a number of reasons, starting with cost and ending with the effort associated with assembly and handling on the ground. Because of the limited market and the high cost of design and certification, a manufacturer must make compromises that limit the realized racing performance. One of the most significant compromises is to design a wing planform for a single place competition ship that can also be used for a two place sailplane.
