Jack Jack, You left the "r" out of "skewed," and it's spelled with a "c" not a "k." Bullwinkle Pretty much. But hey, as long as _everybody_ feels they got s(k)-cr-ewed, then it all went as well as could be expected. The "glassholes" will be the ones who get to fly until they are 65, but they will bitch about having to do the extra five years. 'Twas ever thus. Jack |

Actually, the 787 is built from basically the same material as the
SparrowHawk, so it is not likely to have much problem with that kind of thing. A little bit different resin in the prepreg and it is laid out by machine, but the fibers are exactly the same. Not likely to be many bumps as there are many co-cured parts and the material is very stable. 6 year old SparrowHawk number 1 is still very smooth. Painted - gelcoat would turn brown in the oven! Pretty much all of the other gliders are built with rather old technology when it comes to resins and tooling. No one who wants really accurate, repeatable parts does assembly in the molds or uses wet lay-up. There are good reasons other gliders are built the way they are. Tooling is very expensive. There has to be the right number built to pay off the tooling. With the number of Discus' (Discii?) or LS4's built, it would have probably been cheaper in prepreg - assuming of course, that you were starting production sometime since 1995. Typically, it is hard to make that bet in the world of glider manufacturing.

This got me wondering about the construction techniques of glider wings vs how Boeing does it. Will the 787 have spar bumps after a few years? Are the wings pulled out of molds? Do they buy gelcoat from the same German manufacturer as SH or Schleicher? Or are they painted in poly? Any Boeing types out there with some insights? |

PIKs were built in an autoclave, though I'm not sure they were done in
prepreg. My 31-year-old sailplane still doesn't have a spar bump... unfortunately, the molds were't terribly stable... Jack |
