Abstract
Please note, many of the figures in this issue contain colors and Technical Soaring, for cost reasons, is printed in grey-shades. However, Technical Soaring is online in full-color at journals.sfu.ca/ts/. Therefore, to see the colors, please view the online issue.
On the opposite page is the call-for-papers for the XXXI OSTIV Congress. The Congress will occur between 8 and 15 August 2012 at the site of the FAI World Gliding Championships for the Open, 18m and 15m classes in Uvalde Texas USA. All OSTIV members and non-members, as well, are encouraged to submit papers for presentation. These papers, then, form the core content for future issues of this journal.
After the Congress call-for-papers, appear the OSTIV presentations to be given at the Soaring Society of America Convention in Reno Nevada USA between 2 and 4 February 2012. This event is being organized by OSTIV Honorary Member Bernald Smith.
The first article in this issue, by Jim Short, documents the enthusiastically received 2011 celebration of the 1911 record soaring flight by Orville Wright over the Outer Banks of North Carolina USA.
The article by Peter Wooley, reprinted from John Roake’s Gliding International, revisits the controversial variable-geometry wing as applied to gliders. The article chronicles the work of long-time aero-dynamicist W. A. T. ‘Fritz’ Johl.
This issue continues the publication of papers presented at the 2010 OSTIV Congress in Szeged, Hungary. In a two-part paper, François Ragot carefully explains his views on the total energy variometer. Do not be put-off by the detail because there are many practical gems for the glider pilot therein. Associate Editor Mark Maughmer located the reviewers and supervised the review of the paper and Matthieu Scherrer assisted Ragot in revising the paper.
To assure accuracy of the published articles, each senior author received a galley-proof for corrections-only prior to publication. I applaud the team that produced this issue on time: associate editors, peer-reviewers, authors, copy-editor/layout person, printers and distributors. Thank you!
You are invited to send the editor comments on papers so a useful dialogue with the author(s) can occur in Technical Soaring. Guidelines for comments can be found at www.ostiv.org (editor).
Back-issues, from Vol. 31, No. 3 (July-September 2007) to the current issue, are online at journals.sfu.ca/ts/; earlier issues will be put online as possible.
Finally, it is my pleasure to announce that, beginning with the next issue, Dr. Judah Milgram, long-time OSTIV member and publisher of aeronautical engineering text books (www.cgpp.com) will become the OSTIV Chief Editor and Technical Soaring Editor-in-Chief. For the foreseeable future, I will continue to manage TS online. It has been my honor to serve OSTIV and TS.
