I've seen some pretty clever repairs on about this magnitude, so I respectfully disagree. For example, there was the Genesis where JJ basically created about six feet of wing from scratch. It took him a winter of on-and-off work, and turned out so nice you could not tell the wing had been repaired. Thanks, Bob K.http://www.hpaircraft.com Hi Bob, AIG salvage will (should) tell you who got the DG-500, but they won't tell you how much the bid was. My Genesis had the last 6 foot of the left wing severed by a steel fence post. I contacted Marskey (one of the designers) with my repair scheme and got his OK to proceed. I made top and bottom templates at root, tip and inboard end of aileron from the good wing, then set the bottom templates on my level table arranged to accept the left wing. Laid in the two pieces and checked for straight L/E & T/E + straight top and bottom. Then I removed the carbon rods from the top spar cap on what would be a 150:1 scarf ratio by grinding out each rod, one at a time using a skill-saw with a 8" abrasive disc. This moved the repair inboard some 6', just before the location of wet-wing ballast tank. When all rods had been removed, I prepared the replacement rods by laying in each new rod every 3" which = 150:1. Things got a little complicated because the original spar achieved a taper by dropping a rod every few inches. Had to make sure all the new rods went as far as possible ( root spar cap starts with 100+ 1/8" carbon rods and the tip has 18 rods. The rods are wrapped in one layer of thin cloth (92110), so we laid a strip of that in before gooping each rod with epoxy an flox before laying it in its new hope. Working fast, Pat and I had them all in place in 45 minutes, wrapped the 92110 over the top, laid in a strip of peal-ply followed by a 2X4 with lead weights on top of it to achieve a compact unit. Next, I repaired/replaced the spar web and drag spar + as much of the lowes shin that were accessible which gave the newely re-joined wing pieces some regidity. When all that could be done from the top was accomplished, we carefully hoisted the wing up and rotated it upside down and laid it into the top templates. Then.....................did all the above again on the lower spar cap! *I estimated I had 25K in the repair (at my normal shop rate $65/hr. When all was finished and post-cured we proof-loaded both wings to 5.3 G-s.................they took it without a groan and didn't hardly bend! A fun and challenging project. I planned on selling it, but got to liking it too much and with a new wing fairing and a few other tid- bits, she will climb with most ships..............won't out-climb anybody, but as delivered the ship wouldn't climb an inch in a 1 to 2 knot thermal. Believe me, I have tried...................she always did run well, the faster you go, the better she runs! Cheers, JJ PS, Just finished installing a ballistic parachute from BRS. The Genesis was designed for this system, so the hard points and hatch were all there. Wow, awesome. |
