The journal for the RC soaring enthusiast
If you'd like to support the continuation of the
RC Soaring Digest Archives
please consider making a donation.
35 years and more than 400 issues, the December 2018 edition of RC
Soaring Digest was the last to be published.
The RCSD Archives contain downloadable PDFs of all of the issues starting with the first from January 1984. These Archives will be readily available for the foreseeable future.
We highly recommend RCSD PDF files be downloaded to
your computer HD/SSD where they can be opened with Acrobat
Reader 5 or higher. Viewing the PDF within a web browser via a
plug-in is not reliable.
|PDFs of all RCSD issues can be downloaded
from the RCSD
These PDF documents require Adobe Acrobat Reader 5 or higher for viewing. If you do not have Adobe Acrobat Reader, you'll need to download this free software from the Adobe web site.
If you have questions concerning downloading and viewing PDF documents, we encourage you to look at this page.
|RCSD Special Publications and Preprints
dynamic soaring of salmon. How salmon gain
upstream thrust from pressure gradients and extract energy from
velocity shears. Plus other strategies for upstream energy
minimization. Authored by Philip Randolph Patten. This is a
preprint, for more information on this technical format see this
Isaac Newton’s falsely dismissed theory of inertially caused pressure resistance. Newton’s theory vs. d’Alembert’s paradox, each correct within differing conditions not knowable in the 18th century. 42 pages, 20,571 words. Authored by Philip Randolph Patten. This is a preprint, for more information on this technical format see this page.
Isaac Newton's theory of inertially caused pressure resistance, reinstated.
Flow separations and instability drag as the mechanisms of Newton’s theory and the theory’s defeat by d’Alembert’s paradox, each correct within conditions only differentiated in the 19th century. An amusingly convoluted history. 14 pages, 5474 words (plus endnotes). This is a shortened version of the above aimed at journal publication. Authored by Philip Randolph Patten. This is a preprint, for more information on this technical format see this page.
|Walter Jaburek of Vienna Austria has
scanned the complete Understanding
Thermal Soaring Sailplanes series written by Martin
Simons and created a single PDF which includes all of the
articles. This series of articles appeared in RCSD
starting in January 1990 and ending in the November 1991 issue.
There are direct references to F3J, which had just been made an
official event but the topics covered are easily related to all
forms of RC soaring. Topics include the sailplane polar, weight
and ballast, turning, drag, scale effects, performance
calculation, moment arms and tail volumes, and horizontal
stabilizer considerations, along with numerous others. Well worth
the 5.6MB download.
|RC Soaring Digest / B2Streamlines is pleased to be able to make available the DIAMANT Archive containing materials belonging to Art T. Babiarz, Jr., owner and caretaker of Flug- und- Fahrzeugwerke AG DIAMANT 16.5, serial number 012, N1193, XX. This vast amount of material is more than likely the largest collection of DIAMANT information in existence.|
|PDF versions of Slope Soaring News, published February 1988 through February/February 1990 by Charlie Morey. All twenty issues are now available for downloading.|
|INDEX thru 2005||A complete index for all issues of RCSD through 2005. The search engine is now configured so the results have links to the respective PDF files.|
