built up wood spars for aircraft larger than Ultralights,
All, I am looking for aircraft by name for any that have or use the built up wood spars in them.
Example, Minimax uses a 1/16 plywood face web on the 3/4 x 1 upper and lower caps.
I am looking for aircraft that gross at 1320 or better, and use the I Beam and Plywood with upper and lower caps, or the box play and upper and lower caps.
i have the dimensions for the LMA 5, aircraft spar dimensions, that wing uses 8 and 5 inch tall spars.
i am looking for 6 inch and 5 inch spars. and suggestions
Thank you Robert
Kr2s. , gross is much lower though
Stinson L-5 has a box spar. Going even bigger would be the Fairchild PT series.
Ok, that is 2 to look up, thank you vaflier, and Craig. its an experiment. have a great week.
Pietenpol Air Camper as modified for use in the UK, uses built up spars using 7/8" & 3/4" square spruce capstrips and 1/8" ply web on mostly one side. Various blocks between capstrips and ply on second side for portions of the spar.
The aircraft is limited to a MTOW of 1200 lb.
i found those as well, I just got home with my new frame, so I can start building up the wing profile, and moment of inertia, that the tail has to produce in order to fly it cleanly.
at this time the frame has a wing to tail coupling issue, I have to fix.
