    130 deg Flush Head Fastener Metal Joint Allowables

I used MSC/Pal back in the 1990s and recently stumbled onto my old collection of PAL2 model files. Some would be pretty useful to me right now, if I...

    Buckling limit of spruce longerons for homebuilt aircraft

    Guys, thanks for the help but I already have properties for spruce. To clarify, what I was hoping to find is what criteria to use to determine buckling stress for wooden columns- is Eulers useful for a non-isotropic material like wood, or do I need to use something else? In commercial...

    Buckling limit of spruce longerons for homebuilt aircraft

    Hi Eng-Tippers, When designing a homebuilt aircraft fuselage with 1/2" square spruce (wood) longerons that can see compressive loading, what criteria should be used for buckling limit? I'm working on designing my own aircraft, and I have searched Bruhn's 'Analysis and Design of Flight Vehicle...
