| Résumé |
In 1991, Peter Masak produced a booklet titled Performance Enhancement of Modern Sailplanes which described not just the theory, but the art of performance modifications, including winglets. In it, he credited Dick Johnson, Wil Schuemann, George B. Moffat, Jr. and Richard Schreder for their pioneering work that inspired him.
Despite the wealth of information available on the science of aerodinamics, only bits and pieces of knowledge are available related to the 'art'. This booklet is an attempt to help unravel some of the mysteries of the performance enhancement techniques that some of the more succesful competition soaring pilots have used to help them win. |
