NEW SELIG AIRFOIL BOOK ANNOUNCED.

The new wind tunnel work that Michael Selig and his graduate students have
completed at the University of Illinois, is now on paper and will soon be
available. This work is titled "Summary of Low-Speed Airfoil Data - Volume
1". It's volume one because of the continuing nature of the wind tunnel
program at UIUC. We expect there will be a volume two (and more) based on the
the next period of testing which will begin during the next school year. 

"Summary ......." is 317 pages of narrative and data much like "Airfoils at 
Low Speeds" (SoarTech #8).  There is more narrative, and the book is 
organized differently, but it is obvious from reading through it, that it 
is the next installment of the same basic material.  We've set the price at 
$25 in the USA - which includes postage.  All of the actual tabulated data 
and airfoil coordinates (but none of the narrative or illustrations) in the 
book will be available on-disk as well.  The price for the disk data in the 
USA will be $15 including postage.  Add $4 for international surface mail.  
For Air Mail to the Western Hemisphere add $6.  For Air Mail to Europe add 
$13, and for other parts of the world add $17.  For disk orders from 
outside of the USA add one dollar to it's price - all separate disk orders 
will be sent by first class airmail.

A significant portion of the price received from all book and disk sales will
be returned to UIUC to provide part of the continuing support for Michael's
ongoing test program. 

The printer will finish sometime in July and I will begin filling orders for
the book immediately. If you want to order the book and/or the disk you may
do so now. SoarTech isn't big enough to handle credit card orders, but you
can question me directly by email, or send regular mail to SoarTech
