One of my contributors to EAA Chapter 88's newsletter is a retired Beechcraft engineer. His article for the January issue was on vortex generators. Anyone who wishes to read it can drop me a post and I'll send along a pdf of the Beacon. If you have a phone modem, be sure and tell me and I'll send it at a convenient time for you as it's about 1.5 megs.

How about going to your EAA Chapter 88 web site, click on Beacon newsletter, then scroll down to pg 5?

A lot easier than fax'ing.

John, The old webmaster used to keep the newsletters in the members only area. I didn't know the new guy had changed the policy.

Hey Gang:
Check out the photo on Rick's EAA Chapter 88 Newsletter, page 8:
http://www.eaa88.org/beacon.pdf
A trio of homebuilts execute a loose version of the starburst
Might be loose to Rick, but not to the participants.
I think Karen Cottrell or Larry took that photo at the Alvord Desert get together May 2005, the year we all camped out on the dry lake.
Brings back many fond memories of our adventures.

Rick, I sent you a email asking for the article, but then took John's advise and went to the page directly. so disregard the original request.
The problem with the VG's is of course the placement, but even with a blind placement such as I have done, the reduction in stall speed is remarkable. I was wondering if perhaps a leaf blower could be used as a makeshift wind tunnel to determine the best placement for a Kolb wing by using tufts. Since sage doesn't have any leaves to blow, I do not own one. I should think that someone should be able to angle the blower on the wing to duplicate the angle of stall and move some VG's to the point that the air reattaches. One set up should be viable for all Kolb wings, or at least most.
Oh, the picture of the "starburst" was taken by my wife, Karen at the Alvord. She thinks that you should give her credit for it. The next newsletter, with a link so that she could actually verify that you did give her credit would most likely keep her from hunting you down. By the way it was a good newsletter, I've done a few myself and know how tough it is to get something to fill the space.
