There is no such thing as an "aerodynamic center" of a wing. In rough numbers, the equivalent moment arm of a 22 foot wing will be approximately 4.67 feet out from the centerline. On a 30 foot wing, the effective moment arm will be approximately 6.37 feet. This means that the spar loading will increase on the order of 36 percent with no change in aircraft gross weight. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: KR-2S performance and the proposed Sport Pilot License From: "John Weikel" Date: Sun, 20 Jun 1999 07:13:42 -0500 X-Message-Number: 2 I have considered putting a layer of e-glass at 45 deg on each face of the spar with a unidirectional tape along top and bottom spar cap. That should stiffen it up a good bit. An extended (2 ft or so) center spar section that has been stiffened with glass and the standard wings would give a little more wing and a larger flap area.

For that matter once the spar cap size was determined you could build the rest of the wing "as plans" just longer. The term "aerodynamic center" threw me though. :o) This project (KR Sport Pilot qualifier) could be a very simple if all one did was stretch the wing to allow a little more wing area. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Filling and Sanding again! http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: KR-2S performance and the proposed Sport Pilot License From: Mike Mims Date: Sun, 20 Jun 1999 08:42:15 -0700 X-Message-Number: 5 John Weikel wrote: > > Unfortunately my center section spars are already in place. > John W If you haven't glued in the pieces (wedges) above the spar you could cut yourself a piece of spruce that's as wide as the spar (front to back) and about 1/2 thick and glue it to the top of the spar. Of course now your airfoil for the center section would be thicker but hey you might get more lift to help you with that 39kt stall! :o) PS there is a program out there that allows you to figure the strength of spruce spar caps.

From: Michael Geoghegan Date: Sun, 20 Jun 1999 13:19:11 -0400 X-Message-Number: 9 In way of introduction, I am the builder of a standard, per plans, KR-2. I have been listening and enjoying the dialogue on KR-net for the last 7 months. You should all be complemented for your efforts toward the common goal of builder support. It is a drive which always seems to overcome the many controversial issues involving opinions, personalities and experience. I have learned much from listening and I hope in the future I will feel qualified to contribute often. I am presently working on my ailerons and hope to have them completed within the week. The rest of the project is completed except for the dreaded filling, sanding and painting. I have a 1700 cc VW installed with alternator and battery but no starter. I have included the required instruments and have added turn and bank as well as navigation lighting. I have a duel stick setup and have included MAC grip trim control on the pilot side. The stick controls the 6A MAC elevator servo and a S8 aileron servo. The elevator servo fit very nicely in the elevator and controls the trim tab as per plans. The question I have regards the aileron trim. The servo is small enough to fit in the aileron but I don't have any idea how big the trim tab should be. I can construct it as part of the aileron similar to the elevator trim but the S8 instructions suggest having it operate one side of a piano hinge which has the other half imbedded in the trailing edge. Does anyone have any experience with an aileron trim tab and would a 1" by 12" wide hinge tab do the trick. Do we have any takers on this one?

KR plans specify 2.0" caps for center spar. Some people are using thicker (2.5"). If you are using 2.5" caps, a two foot extension should be no problem. Otherwise its is the top cap of the enter spar that is the most loaded (in compression) . You will have to somehow strengthen it around the root. In any case you should keep building and keep it light. You should be OK then.

When you combine material with different physical properties, you will get unexpected consequences that require a very careful analysis and testing program. The glass and wood will strain at very different rates. That is, when you put a load on them, they will tend to stretch at different rates. That can very drastically affect the failure mechanisms of the overall structure. Without testing, it is very difficult to predict the behaviour of this. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: KR-2S performance and the proposed Sport Pilot License From: Donald Reid Date: Sun, 20 Jun 1999 22:23:25 -0400 X-Message-Number: 23 JEAN wrote: > > The aerodynamic center is a point that your aircraft balances > aerodynamically.

Anyway if you were to increase your wing are to say 90 sq feet then your horizontal tail should be something like 15.4 square feet on a stock length KR2S. This according to Roncz data. Of course I didn't double check but the numbers but the stuff that's available in this techno age is way cool! -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Filling and Sanding again! http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: KR-2S performance and the proposed Sport Pilot License From: "JEAN" Date: Sun, 20 Jun 1999 23:08:58 -0500 X-Message-Number: 27 According to Martin Hollmann ( Modern Aircraft Design, volume 1, 1986 ) and David B. Thurston ( Design For Flying , 1978 ) the aerodynamic center is calculated for an aircraft with an aspect ratio of 6 is : SX + .4 S1 X1 Xac = ------------------- S + .4S1 This is only good for a conventional aircraft with the elevator in back.

I found long ago when trying to sand polyester resin. If you will mix just enough liquid detergent in your water to make it feel slipry, the wet/dry paper will last a lot longer.
