I have a hypothetical question to the net and I'm sure it's been either done or thought about. If one decided to mate a KR wing set to a truss type steel tube fuselage how would one go about doing it? . My thoughts are to go with a Sonerai 2 style set up as it is a center section with 2 outer wing panel style wing set not too dissimilar to a KR wing . Using 1/8 inch wing attach fittings more or less as per wing attach fittings but installed on the juncture of where the fuselage and center spars intersect, bolt the spar to the fuselage with 5/16 inch mounting bolts through the upper and lower spar caps on center through the fittings through the spar. How would one bolt the wing to fuselage attach fittings to the spar, would you use the same bolt pattern as on the wing attach fittings or use 1/4 inch bolts on center of the fitting 3 on one side of the 5/16 inch mounting bolt and 3 on the other side. I hope my question is clear enough ------------------------------ Message: 5 Date: Sat, 15 Oct 2005 10:39:10 -0700 (PDT) From: Dennis Mingear Subject: Re: KR> steel tube fuselages To: KRnet Message-ID: <20051015173910.75518.qmail@web51402.mail.yahoo.com> Content-Type: text/plain; charset=iso-8859-1 Interesting idea, I'll let others comment on the more technical aspects of your post, but I would be interested in the weight difference between the wood and steel fuse.

Finished fabric covering is the lightest at 6 oz. per sq.yd with fiberglass sheeting coming in second or last depending on how well you do it to aluminum covering being the heaviest .025 2024T3 is about 2.75 lbs per sq.yd by my rough calculation. as the fuselage only has about 3 sq.yds of covering there is really not much difference in weight. Fiberglass is the easiest to tie wing roots and horizontal stabilizer into and I know of a Smythe Sidewinder that uses fiberglass skins because it was lighter than .025 aluminum skins and the aircraft is beautifully builtennis Mingear wrote: 36 pounds, without covering or paint.

I have a wooden fuse in the garage now, but I've always wondered about a steel tube substitute based loosely on the Sonerai. Looking at the numbers you've provided it might be possible. I've always thought that a wood stringer and fabric turtle deck would look nice on a KR and it would be very light and easy to make too. A steel fuse would finish off the plane so that it looked more like something out of the golden age of aviation. Some nice wheel pants and streamlined gearleg covers would complete the look.

The VW powered stuff seems to fit into the LSA rule fairly nicely, the stall speed is still a problem though. Look at what Monnett has done with the Sonex ans Waiex, they are both LSA compliant. Any KR builder can do the same with his KR. As I recall, to use the stock KR2s wing you would have to limit your gross weight to something like 950 pounds to meet the criteria that Monnett uses for His planes. It can be done, but, do you want to put up with the LSA limits imposed by such an approach.

If you look at the early KR2 plans it calls the stall speed as 42 mph Dennis Mingear wrote: Most KR's are not as fast as most people think they are. The VW powered stuff seems to fit into the LSA rule fairly nicely, the stall speed is still a problem though. Look at what Monnett has done with the Sonex ans Waiex, they are both LSA compliant. Any KR builder can do the same with his KR. As I recall, to use the stock KR2s wing you would have to limit your gross weight to something like 950 pounds to meet the criteria that Monnett uses for His planes. It can be done, but, do you want to put up with the LSA limits imposed by such an approach.

You need some engineering analysis, not just a "that looks about right" feeling. Based on my analysis of the KR wing, if you took a KR outer wing panel and moved it to the root of a fuselage, 3 1/4 inch bolts through the wooden spar cap are not nearly enough unless there are large diameter load bearing bushings in the spar cap. The minimum number of bolts that can be used to bolt a spar cap are 4, and the diameter of the bolt or load bearing bushing in that case is 1/3 the thickness of the spar cap. For example, if the spar cap is 3 inches thick, including any taper, you can design a fitting that will need only 4 bolts through the wood, but they must be 1 inch in diameter. Since you would not want to use a bolt that large, they would be about 3/8 and they would pass through a bushing made out of aluminum that is 1 inch OD that is in the spar cap. There are other designs that use a wooden cantilever spar bolted to a tubing fuselage, so yes it is do-able.
