wood in aircraft manufacturing, was First Glider
You can trust a tree, but you can't trust a glue. Due to a catastrophic in-flight failure of a Robin DR 400 wing, the French authorities discovered badly glued wingspars in a lot of airplanes of this type. Consequently, reinforcements have been made mandatory (C.N. 2003-348). To see how this is done, look at: http://perso.wanadoo.fr/malibos.aviation/vp1.html The same occured last year with Duo-Discus wings, so it's 1-1 in the wood-plastics competition. Both require precise mixing of components (glue or epoxy), and correct temperature and humidity control. Perhaps metal isn't so bad after all? But then there is metal fatigue... -- stephanevdv ------------------------------------------------------------------------ Posted via OziPilots Online [ http://www.OziPilotsOnline.com.au ] - A website for Australian Pilots regardless of when, why, or what they fly - |

The secret may be to build aircraft like they did 500 years ago - using
wood, with no glue - just doweling. The other possibility would be to carve the wing out of one big log - like the Indians did. Colin N12 HS - where wood is good, and the pilot is the weak link. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
