Anyone recommend a source for designing hinged wings?
I'm interested in implementing a hinged wing on my to-be-built homebuilt
airplane. I'm looking for design specs/criteria/criteques describing the strengths, weaknesses, reliability, and costs of the most used/popular techniques. Any good sources? Tim Schoenfelder |

Same here, Tim.
In metal, look at the Thorp/Sunderland S-18 http://www.t18.net/ And of course, the Grumman Cats of WWII. ;- In wood, the Cvjetcovic CA-65 http://www.hinkleymall.com/ca65.html has a folding-wing option. There are not a lot of them around, though the design dates back to the 60's. Not sure why - it seems to be a decent design. But there seems to be more support for the Piel CP-301/328 Emeraude Falconar http://www.falconaravia.com/ sells plans for a 3-piece wing for the Emeraude, which allegedly can be built as a folding wing. It adds about 40 lbs, and is non-trivial to operate. I'm thinking about it, but would probably modify the design to split the flap (so as not to have to remove it) and add Thorp-style aileron connections (to avoid having to re-rig the wing). As I said, non-trivial. Check the archives of the Emerauder group on yahoo. Also look at this newsgroup a month or so back for a thread on high-strength hinges. The Bowers FlyBaby also has a folding wing. Pete Bowers could set it up or take it down in about 15 minutes, according to http://home1.gte.net/ikvamar/flybaby/folding.htm/ The Evans VP has a removable wing, but it's not a folding wing. You have to disconnect the front and rear spars and four braces, not to mention the aileron cables. I'm not aware of any folding-wing designs in glass or carbon.

Do a google on "glider" and "folding wing". There are a couple of examples. I know the Stemme motorglider has folding wings. Mike |

I don't think that I wish to spend several thousand hours(I don't have that much time) building it like some of the composites and more complicated metal planes take.

My objectives are similiar to those that you state on your website. However, I do have relatives a state away that I'd probably fly to visit with it. Tim |

Tim These are all good suggestions but if you are building a light plane you might want to take a look at a couple of others. The Kitfox has elegant folding wings: http://www.skystar.com/images/wingsfolded1.JPG The RANS company has several models of airplanes with folding wings. The S-6 Coyote II is just one example: http://www.rans.com/3V/s-6es.htm Rick Pellicciotti, Belle Aire Tours, Inc. http://www.belleairetours.com |

Hmmm
If you JUST wanna fly...and arent really interested in going very far or very fast consider a gyrocopter......faster to build, cheaper to buy, easier to trailer and store....plus they can take off in short distances and can almost land/stop on a dime (comes in handy for emergency lands I would imagine...) take care BLL |

Quite right, Rick. I completely left out the tube-fuselage and high-wing designs.
