On a real airplane if the hinge broke and came loose you would be picking up more than broken peices of plane. Another words you would be SOL. I would be inclined to use the Dr. Deans hinges myself.

I just want to say that I've been following the comments that have been made on this site for only a couple of weeks. This site reminds me so much of a government think-tank. You good folks come up with some VERY, VERY interesting questions and comments, like the one below made by Ameet. If you think about it, this is where "cutting-edge technology" starts - by interested, dedicated people, like yourselves asking questions, making comments, trying new things, and coming up with new solutions. I belong to quite a few aviation discussion groups, but this one runs circles around the rest. I'm hyped! Keep up the fantastic work!

Load is not just a function of airspeed it also depends on size of the control surface (among other things) 200 mph of an small R/C plane is not the same load on the control surface as 200mph for a full scale airplane. As I mentioned earlier, R/C gliders use "KEVLAR" for this purpose. I don't know the theory behind it nor the numbers to justify the fatigue life. But there must be some logic to it and might be a good start for someone to investigate such a hinge method.

The PFA (our EAA) have stipulated a mandatory modified WAF arrangement for the KR2s which I mentioned on the net a couple of months back which has doubled 16g heat treated s515 plates as well as exrta AN4 bolts through ally bushes thro the spars (I can send you a drawing if you like). Thier justification for it is that the increased stresses induced by the increased dimensions of the KR2S push the KR2 WAF design too close to the limit. I am inclined to say "if it aint broke why fix it?", but this is what we have to put up with over here.

Regards Mac Steven , I used the basic /original aileron system . The problem I had obtaining full aileron travel was resolved when I checked the distance between the aileron hinge and the the horn bolt hole center . It has to be 2.5" max . If any longer than that you won't get full range of movement. This dimension was omitted on my drawings but they are Very Old!

With the exception of a "fiberglass hinge", it's all been done before. It's just a matter of whether or not you want to adapt it to your KR. Personally, I see no advantage to any design discussed over the original piano hinge. I was struck dumb the first time I saw the aluminum hinge on a Zenair 601 and couldn't believe what I was looking at. I guess it works just fine but to me,adapting that to a wood, foam, and glass wing is like running on a treadmill, you're not really getting any place. As for testing the glass hinge, you could have your KR built and have 500 hours of air time while you build a test rig to test the hinge for failure. Just no payback. This post is not intended to shut down creative thinking. I'm just adding a dash of reality to the technology stew we're cooking.

What is the flexure lifetime. The resin would probably fail before the fibers but how long? I don't know and I don't have the data. In addition, laminated construction is very weak in peal strength. It would be difficult to design an all-laminate flexible hinge that does not depend on resistance to peal unless you use mechanical fastenings. You could do it with an aluminum plate, but again, it would have to have mechanical fastenings and require additional testing. Why would you want to change?

It just seems that in rapid entry of a steep turn, one wing is trying to lift the airplane while the aileron on the same wing is trying to push it down, quickly. This seems like a pretty good "shear" stress on the edge of that .016" aluminum skin hinge.

If the hinge plate would always be constrained to a smooth arc then I would think it would be no better or worse than the current methods. But, if it could be excited into a buzzing condition where the hinge were assuming something approaching a sine wave I would think it could be even worse that the typical flutter scenario.

The hinge mechanism used would have little if any effect on flutter. I too am opting for Dr Deans approach on all hinged surfaces. A little costlier to build but hinge service life will be much longer and friction a non-issue. Doug Rupert -- No virus found in this outgoing message. Checked by AVG Free Edition.

Once the resin is added however all these properties go bye bye. Many forget that composite is just that, a composition of different materials to result in something much stronger than any of the other materials used alone. The idea itself is good but I cannot see where it could be of use to us unless as you stated. If going to imbed aluminum into the skin as a hinge then it would be as easy if not easier to install the plans type hinges, or better yet the Dr. Dean type. Both have been tested perform, are in wide usage and do not have a finite lifespan with proper maintenance and inspection. Just my opinion. Doug Rupert -- No virus found in this outgoing message.

Click on that one and about one or two pages down you will find: "Figure 2: AN Aircraft Bolt Dimensions" Click on that one and you get a whole table of dimensions. Perhaps that helps. Otherwise, there are beaucoup more hits on Google.

Flutter is primarily a function of the natural frequency of vibration. A stiffer system would increase the natural frequency so a plate hinge might in fact be less likely to flutter. But on the other hand, I have never thought that much about it. Composite construction does not lend itself to this type so I am not worried one way or the other.

Question 2 probably 12-32 which would be a machine screw not AN. I don't know what the numbering system for screws was based on, but as stated, #10 is equivalent to 3/16". The next smaller size is #8 at @ 0.16". #12 is larger, I "think" equivalent to 1/4" Allen G.

As an ultra lite trainer you get extra weight allowances.----just a thought _______________________________________________ No banners. No pop-ups. No kidding.
