I think that's a great plan, or maybe even just add an inch to each of the bays behind the aft spar. That longer moment arm will help the stability, with a miminal increase in wetted area. I'm 6 feet tall and I sure wish I had that extra 2 inches in front of the main spar. I'm just about out of room for rudder pedal travel. The spars determine the seating (you can't sit on top of the rear spar unless you raise the canopy about 5 inches) so you're "stuck"...

Weather forecast for the end of the week here in KY. Friday, sunny temps. of 72/49 Saturday mostly sunny temps of 74/52. Looks like mother nature is going to cooperate. Picked up all of the hats, shirts, awards SHADE yesterday. I will be flying out tomorrow afternoon to Lake Barkley. If you need anything be sure and get hold of me today or first thing Weds. morning. It seems like a lot of this falls together in the last couple of weeks as far as forums, attendees, etc. are concerned. It is shaping up to be a great gathering. One thing you will see, other than KRs, is that everything is for sale. Nobody is making any money on any of this, it is simply the only way we can financially pull this thing off. With that said, buy a hat, buy a T-shirt, donate to the fuel fund, donate to the gathering fund. I've spent over $1000.00 in the last two days, and I'm not done yet. It ain't cheap, and putting this thing on takes a lot of time. One person can't do it, it takes volunteers. For those of you have helped, thanks. If anyone can volunteer to man a table for an hour or so to help register people, sell KR items, sell banquet tickets...........anything be sure and look me up, I will appreciate it and in doing so we can pull this thing off. For those of you driving in, be sure and sign up for the car pool. We can sure us you.

Checking the bolt holes at the landing gear attach would be a start, looking for any elongation or cracking of any kind (or, obviously, bent bolts or fittings). Also, the V-wedges and blocks that secure the spars into the fuselage sides might show cracking at the glue lines or elsewhere if things had gone past yield. If it's the retract version, a hard landing would probably have punched the gear up through the wing. On the fixed gear, there's no telling. I'm sure you'll get much better responses from folks like Jeff Scott or Don Reid; Jeff has good experience in what to look for when buying a previously-owned project or airplane, and Don is a "fer real enjinear" who knows about the structural design limits. Load testing the wing spars would involve distributing weights over the wing surface (sand, cement, fertilizer, whatever) to design load and wait to hear a cracking sound ;o) I don't know what the positive design load is on the KR (4G?) For those on the Net who don't know, John is a proud new papa. He was busy working on his KR last week when his wife reminded him that she had started into labor 12 hrs. earlier and needed to get to the hospital in Reno, but he had already mixed up a batch of epoxy and couldn't stop, so she drove herself. (Just kidding about that last part)- but now John is spending some of that quality time burping his new baby daughter and changing those diapers. Congratulations on your new little student pilot!

I got my wife to sit on a bench with me and used two boards to determine the width limit. We will fit but if I gain a pound, she has to loose one. Funny thing, she didn't show a lot of interest in the plane until after this little drill. Go figure..... We also did a fit try after the fuselage was built and she appeared eager to sit and help me make engine sounds. I asked her to select upholstery colors and had the upholstery in place for the fit test.

I'll send you a cigar with the rudder horn (or is it the elevator horn?) modification. Anyway, I've been sneaking out to the garage when the baby and mama are sleeping and getting alot done on the KR. The main gear (the origional retract) will be going back on and it will be rolling for the first time in 14 years...yeah! And yes, the gear punched through the wing stubs when it crashed. There are no visable problems with the CENTER spars (sorry for being vague), except the rear spar has a crack in the top from tooooo large of a screw for the sling seat. It is this type of find that makes me scepticle of the origional builders competence, thus the desire to test the spars. There are several glue joints that have seperated from the impact, but I have cleaned them up and will inject structural epoxy back into them. My Instructor and A&P has been overseeing the rebuild but he admits not knowing a lot about wood. I have located a BRS chute and will install it, but I would rather not have to rely on it and the extra 30# will hurt. Engineers, please help....how much weight would it take to simulate 6gs? Any suggested reinforcements or modifications?

Which direction must the fibers be oriented to strengthen it in > case of flutter? Like the wings and other control surfaces, the fibers need to be at a 45 degree angle to the fuselage centerline (or elevator hinge line). But flutter isn't just a trailing edge phenomenon, it involves the whole control surface. If you're building a stock KR tail, you shouldn't even worry about it, since it's been proven for 25 years. But if your trailing edge is flimsy, that's a good enough excuse. If it'd make you feel better about whatever you're building, wrap the whole elevator with a layer of carbon fiber at 45 degrees to the hinge line. They don't sell carbon fiber (or fiber glass) tape at 45 degrees, so you'd have to wet out a square of it on plastic and then cut it up into strips... I only used carbon fiber on my wing because I'm using monster flaps, and to lighten things up a bit. I beefed up the aft spar, but I'd also like for some of that load to be transferred through the skin to the main spar as well. My fears were probably unfounded though. After glassing my inner wing skins (and before I added ANYTHING to the outside) I could lift the wing (and tilt the plane) using the aft spar, and the incidence wouldn't change...

Is there any way to place a > "load" on the spar to see that it will hold? How much weight for the > forward spar? The aft spar? This one is way too much to answer in this type of forum. I can give some general answers and you will have to find the rest yourself. The other responses have been very correct about the inspection process, look for cracks and bolt hole distortion. You should know that wood, as a structural material, is different than steel or aluminum. If there are no cracks and the bolt holes are unaffected, the wood is almost certainly just as strong as when it came from the tree. If you want to do a load test: 1) Take the gross weight of the aircraft, including ALL people and baggage, fuel, and all the rest. From that weight, subtract the weight of everything in the wings, outboard of the fuselage. If the fuel is all in the fuselage, the fuel adds to the load on the wing. If the fuel is in the wing, subtract it from the gross weight, along with the weight of the wing. The number that you end up with is the load that will cause a bending moment on the wing. For your basic 1000 pound gross weight KR2, this will be on the order of 850-900#. 2) Multiple the number from step 1 by the load factor that you want. This number is the total amount of load that will cause bending in the wing. If step 1 is 900 and you want 5 G's, then 5 x 900 = 4500 pounds. Each half of the wing must carry half of the load in stable flight; in this example, 2250 pounds per side. Under gust load conditions, the weight distribution will be different, one wing half will load more than the other. This is why there is a yellow arc on the airspeed gauge. 3) The shape of the load distribution along the wing will approximate half of an elipse. There will be no weight at the wing tips, the load per length will increase rapidly over the outer 1/3 or so of the wing, and less rapidly from there to the wing root. The sand bags (or whatever) that you use will be distributed in that manner. 4) In rough numbers, the main spar will carry about 2/3's of the total load and the rear spar will carry the remaining 1/3. In a load test, the airplane is supported upside down and the sand bags are placed, more or less, along the main spar, in the correct distribution from step 3. A second test can be done with the airplane rigged to simulate a high angle of attack. In the simple load test, the aiplane is upside down, but level. To simulate high AOA, the the plane is supported upside down, with the tail high in the air. There are more exact answers, but you will need to find them in engineering handbooks or similar material. -- 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: Making the KR2S a KRSSSSS From: Donald Reid Date: Tue, 21 Sep 1999 20:10:19 -0400 X-Message-Number: 23 WHin77@aol.com wrote: > So if you could make it longer, how much longer and where would you add it? > My gut says 35" is a little too much.

Don't forget that the pedals take up more space than you think at first. I added 5 inches in front of the main spar over the -2S plans (7" over the stock KR) but I am 6'8"+. I added one inch in each of the rear fuselage bays, they are 15" instead of 14" apart. I am biased, but I think that it looks just about right. I made one mistake on mine. When I widened it, I did not think about the engine. If the natural curve of the fuselage is continued out the engine, the rocker covers will be out in the breeze. I should have widened the firewall just a bit. Draw it to scale before you start and check. -- 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: Main spar testing From: Mike Mims Date: Tue, 21 Sep 1999 17:16:20 -0700 X-Message-Number: 24 John Aberasturi wrote: > > Hi, > I recently purchased a KR2 rebuild project that had been damaged in a > hard landing around 1985.

So if you think you want to join us for the flight down, please e-mail me at the mailto below. We plan on arriving around noon or so.

It sounds like you have a wing from one project and a fuselage from another. Or the original builder forced them into alignment. Without looking, I suspect that your only choice is to plug the holes in the spar caps and re-drill. Use a wooden dowel from a similar type of wood and plenty of epoxy worked into the hole. -- 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: engine website From: ejanssen@chipsnet.com (Ed Janssen) Date: Tue, 21 Sep 1999 23:13:23 -0500 X-Message-Number: 38 This is a multi-part message in MIME format. ------=_NextPart_000_0047_01BF0486.E6BDF240 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Engineheads will want to check out this website. http://www.isd.net/eulmer/engines.html Ed Janssen ------=_NextPart_000_0047_01BF0486.E6BDF240 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable
