tonyslongez Posted July 2, 2009 Author Share Posted July 2, 2009 O.K. Where was I? aah Yes. So I had the aileron molds welded up out of 6061 T6. I made them wide enough so that I could build both the left and the right. Pic 1) Here is the aileron sitting in the mold. the forward portion of the aileron is positioned at 70.deg Pic 2) Here is the aileron mold. I'll need to polish the mold before I make a set of ailerons in it. Pic 3) Here is the bottom of the mold where it was welded. I beveled the front edge at 45 deg. then had the trough filled. Pic 4) This is the bottom skin of the aileron. As you can see this mold will make the top and the bottom. Dale and I will be doing some layups this week.

Nemesis Posted November 5, 2009 Share Posted November 5, 2009 Tony, I hope your previous post was in Jest or Possibly frustration... I have enjoyed the entirety of this thread and have wanted a Berkut for years, I am a year or two away from activly persuing my dream at this time. Family Ilnneses and deaths the past couple of years have drained my resources, but hopefully the hunt will begin anew.. Have you progresed any further on your kit, or ?? I am new to this forum, but not new to aviation. Started Flying when I was 15, soloed on my 16th birthday, etc etc... Also been a Certified Tech. A&P for over 25 yrs... I really DO Admire Craftsmanship.. And you have put in the work on this one... Past job was Quality Control Inspector for Bombardier Aerospace...

Lynn Erickson Posted January 22, 2010 Share Posted January 22, 2010 For my next trick. Billet NG-6If you do build these I would suggest that you do away with the bushings and use ball bearings as I did or a tapered roller bearing like the Wilhelmson units Quote Evolultion Eze RG -a two place side by side-200 Knots on 200 HP.

Lynn Erickson Posted January 23, 2010 Share Posted January 23, 2010 Drew I was going to get rid of it but decided that I would just finish it instead. I'll start posting soon. Lynn I'll be using the tapered roller bearings they do work but the ball bearings are simpler and do not have to be adjusted for preload the ball bearing have built in preload and are a lot lighter in weight. the ones I used are 5/16" id single row sealed ball bearings.

tonyslongez Posted January 23, 2010 Author Share Posted January 23, 2010 O.K. is preloading really an issue? I think ball bearings are not as good as the tapered bearings for this application, the tapered bearings handle the side loads better, and I think, and (could be wrong) but don't ball bearings have a much smaller contact patch than the roller bearings? I don't think I would use ball bearings. Consequently all of the landing gear components that I have collected in the last ten years, not a single one has a ball bearing in it anywhere, mostly just bushings. (with the obvius exception of the Berkut which I have replaced the ball bearings with bushings. Tony Quote Link to comment Share on other sites More sharing options...

Tony the load on these bearings are not that high. taper roller will work but are big overkill I weighed the taper rollers that wilhemson uses and they are almost a pound compared to the ball bearings which weigh about the same as a quarter. the reason to change is that the bushings get worn and you get wobble on the nose gear strut and this has been known to cause wheel shimmy. The bushings do work , for awhile, the small ball bearing seem to be better as I have used them for 400 hours with out any sign of wear changing the bushings to another bearing is not worth doing if you are going to add pounds to the aircraft.

tonyslongez Posted January 23, 2010 Author Share Posted January 23, 2010 the load on these bearings are not that high. How high are they? And how did you determine your conclusion that the loads are not that high?Just so that I may look it up, what bearing exactly did you use?

Any answers? Can you give me anymore details as to how you determind the loads for the nose gear. What bearings are you using exactly? Tony Sorry Skiing comes before airplanes. i will have to check on the bearing numbers I used. and the engineering was done by a retired Space shuttle engineer and he calc'd the loads and spec'd the bearings for me. and I guess he was right as they seem to work just fine. he said the bearing could take the load and the 5/16" bolt would shear before the bearing would break but the ng 30 would be the first thing to go if the loading was exceeded. he said the bolt and bearing has about ten times the strength of the NG 30 Quote Evolultion Eze RG -a two place side by side-200 Knots on 200 HP.

tonyslongez Posted January 25, 2010 Author Share Posted January 25, 2010 Fair enough. I like it. I'll consult my engineering friends as well to see if they concur. I f they do I will make them using a ball bearing. I think the NG-6 could be re-machined to be lighter as well. Tony Quote Link to comment Share on other sites More sharing options...

Tony we also have an SS spacer between the bearings that is .015" smaller then the bore in the casting between the bearing recesses, so even if the bearing was to fail the gear would still pivot but with some play. the bearings are still holding up even after breaking a nose fork and loosing the nose wheel. my fork and fork pivot are now made of billet 7075 alum. the stock long ez fork has been known to break even on some light long ez's.

AVI Posted December 27, 2015 Share Posted December 27, 2015 The last activity on this thread was six years ago next month. Now, nothing much happens on TheZone these days, but ... 1. Did Tony ever finish his Berkut project? Did it fly? 2. Whatever happened to "Canard Gear" the website offering the retractable gear, molded fuselage, and various Berkut/LongEZ accessories? Is the RG mod available? All we get is a 404. 3. Where's Tony? Hope he's in good health, alive and well in Vegas ... Quote Link to comment Share on other sites More sharing options...
TMann Posted December 29, 2015 Share Posted December 29, 2015 Don't know the status of the project/kit that Tony's been working on but I do know that there will be a new kit offering at Oshkosh 2016. They intend to have a flying aircraft there and will fabricate one entire kit there on the grounds over a 4 day period. How's that for real?

gilbertexp Posted March 6, 2016 Share Posted March 6, 2016 Hopefully they take pricing into consideration in their business model. In my opinion the only way a two-place, recreational, home-built kit can be successful is to make it affordable to the masses. Looking forward to it. Don't know the status of the project/kit that Tony's been working on but I do know that there will be a new kit offering at Oshkosh 2016.
