The airfoil surface is dimpled somewhat like a golf balls. This new airfoil has a dimpled surface which when forced through the air at flying speeds actually augments the lift normally created by the airfoil. They discovered this effect accidently when an air force jet flew into a hailstorm resulting in the entire fuselage and wing leading edges being dimpled by the large hailstones. Remarkedly the aircrafts performance was increased by about 7%. Both increased lift and reduced drag were noted. We have all marveled at the way golf balls seem to rise up rapidly and travel great distances. At least when Tiger hits them! It is the dimpled surface on the golf ball that is responsible for the ability of the golf ball to lift up while in flight. Baseball pitchers also use the same principle to make a pitch actually rise a bit when in flight. The dimpling is only required on the front 1/3rd. Of the airfoil. The only problem is that the size and spacing of the dimples is affected by the reynolds no. of the wing so it varies with each aircraft, it's planform and cruising speed. Further in formation on this unique concept can be had by contacting the inventors at Canada air. In Montreal PQ. It helps if you can address them in French because the laws in that Province require them to deal in English only as a last resort.

Hey, the well's dry as far as catastrophes that could happen to my project that haven't already happened. I probably SHOULD sell it to the highest bidder, no more than I've gotten done on it lately! I've finally arrived at the point that I'm tired of people asking when it's going to be flying! I have the usual excuses, such as too much overtime at work, two young kids and their sports schedules, varmints in the attic (now it's giant lizards), ailing father-in-law, too much time on the web, etc. But I did get my cowling sort of mounted this weekend, with hinge pins installed on both top and bottom. I'll throw some pictures out there, but it fits very nicely, and everything lined up better than I had hoped. Now that it's warming up I hope to get some finish work done. If I had any sense at all I'd take that 7 weeks of vacation that I have saved up and get this thing finished!!!! Unfortunately, my real job is really going into overdrive here for the next few months. At least it's fun design work...

I believe it is similar in theory to the Laminar effect. What I saw was fairly small, very regular half-round 'dimples' in the surface over a large area, like the entire leading edge of a wing or the leading edge of the prop. Now, a REAL April Fool's joke would be for me to tell you that I have actually started work on my plane and got the stubs done, the gear on and the controls hooked up and am almost finished with my foreward-hinged canopy... But, I know no one would buy that, so I'll just go ahead and pack my bags, change the oil in my car and get ready to hit the road for Florida this weekend. ===== Frank Ross, San Antonio, TX, __________________________________________________ Do You Yahoo!?

Capps" Subject: new airfoil technology Message-ID: <001d01c1d9b3$6ee04750$0400a8c0@schpankme> WOW guys, are you telling me that after this up-coming hail storm, I'll be able to collect on the damage from my insurance company; and then benefit from a better performing aircraft? Where's my ball pin hammer! Best Regards, Larry A. Capps Naperville, IL “People’s attention is drawn by two things, the elegant and the unsightly. Take it from me, your plane is getting plenty of attention!” -----Original Message----- If I had known about the dimple technology yesterday I would have taken my wings outside. We had a good hail storm so I'm sure some airplanes got the dimple treatment for free.

There was an article in "Sport Aviation" about 5 years ago where they put some tape on a Stearman prop and claimed an increase in prop efficency. But hell, as slow as a Stearman flies you could probably just rub bug guts on the prop and get a performance increase. :) Larry Flesner ------------------------------ Date: Mon, 1 Apr 2002 07:45:53 -0500 To: From: "mike" Subject: RE: dimpled aircraft Message-ID: <001601c1d97b$291f3380$6400a8c0@wolftreeinc.com> ------=_NextPart_000_0013_01C1D951.3FF53F20 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable I may just be plum skeptical ,but , hmmmmmm............... isnt today = the 1st of april?=20 ------=_NextPart_000_0013_01C1D951.3FF53F20-- ------------------------------ Date: Mon, 1 Apr 2002 06:54:56 -0600 To: "mike" , From: "Mark Jones" Subject: Re: KR> RE: dimpled aircraft Message-ID: <002c01c1d97c$6d2ca8e0$07991f41@wi.rr.com> Yea, did you hear William Shapner was arrested this morning at LAX after pilots reported a crazy passenger had discharged a firearm through the window and was shooting at weird creatures out on the wing!~!!~!!!

On thursday we went flying= in a rented Grumman. It was very nice meeting Pat. I enjoyed his company= and hope to see him and many of you on the KR net at the KR gathering. P= at went home with a set of WAFs and I hope a renewed commitment to get st= arted on his KR. Pat and others are welcome to drop in anytime.

Who is planning on attending Sun & Fun? Since RR will not have a booth (what's up with that?) we need to find a place to meet on Sunday and maybe get together over some adult beverages and watch the airshow. This would be a great time for everyone to swap the biggest flying lie they they can boastfully tell:-). I'm getting there on Friday so I can get some good deals with the outside vendors on Saturday before the circus come to town on Sunday. Anybody up for trying to get together Sunday?? Leo, great looking KR. Looking forward to meeting you.
