Editor’s comments
Information on the 100th anniversary of Orville Wright’s famous soaring flight, provided by Jim Short and Bernald Smith of the USA, is on the next page. This event is being planned for the weekend of 21-24 October 2011 on the Outer Banks of North Carolina USA where the flight occurred. So mark you calendars!
This issue completes the publication of papers received from the 2008 OSTIV Congress. Sachs and colleagues present a flight profile for achieving the maximum range for a motor glider with a retractable engine. And, Liechti presents a unique method for predicting aligned lift and for planning soaring flights using the predictions.
This issue begins the publication of papers submitted to and presented at the recent OSTIV Congress in Szeged Hungary. To introduce the Congress, the papers presented at the Congress are summarized by the Chairs of the Technical and Scientific Sections, respectively, Mark Maughmer and Zafer Aslan. Then, the first two papers to be peer-reviewed appear. Gedeon and Dóra present a novel analyses and modeling procedure for chaotic data. And, Fövényi summarizes the techniques used by the Hungarian Meteorological Service to predict atmospheric conditions in support of the World Gliding Championships in Szeged.
Also, this issue contains two contributed papers. Souckova and collaborators report the results of a useful coordinated numerical modeling and wind tunnel study of flow past high-drag devices. And, Hoff and colleagues report a computational method for estimating sailplane mass properties as an alternate to measurements.
The following persons located the reviewers and supervised the reviews of the papers in this issue: Guest Associate Editor Götz Bramesfeld (Sachs, et al. paper), Editor Ward Hindman (Liechti paper), Associate Editor Aslan (Gedeon - Dóra and Fövényi papers), Guest Associate Editor Judah Milgram (Souckova, et al. paper) and Associate Editor Helmut Fendt (Hoff, et al. paper). To assure accuracy of the published manuscripts, each senior author received a ‘galley-proof’ for corrections-only prior to publication. I applaud the team that made this issue possible in a timely manner: associate editors, peer-reviewers, authors, copy-editor/layout person, printers and distributors. Thank you!
Technical Soaring is online at journals.sfu.ca/ts/ and compliments the print copy; the print copy will continue for the foreseeable future. The main benefits of being online are unlimited use of color, access to back-issues and, as members choose to terminate receiving print copies, saving OSTIV money. You must be a paid-up-member to have complete access to TS online and OSTIV must have your e-mail address. So, please either mail your name and e-mail address to OSTIV c/o TU Delft, Faculty Aerospace Engineering, Kluyverweg 1, NL-2629 HS Delft, The Netherlands or e-mail the information to l.m.m.boermans@tudelft.nl. TS online is open to non-members for titles and abstracts. Currently, non-members cannot access complete papers. Access for these individuals eventually will be through the on-line PayPal system. A quick-start guide to access TS online is at www.ostiv.fai.org.
You are invited to send me comments on papers so a useful dialogue with the author(s) can occur in Technical Soaring. Guidelines for comments can be found on the Technical Soaring website at journals.sfu.ca/ts/.
