|

I too have felt a bit uneasy about the slanted spar. It does almost seem like some type of triangular box spar would be better.
One approach to strengthen the spar when encountering loads from the front and below would be to cut a slot in each rib between the front lightening hole and the spar perpendicular to the spar, and then insert a “mini-spar” through all of the ribs. It would be attached to each rib with a triangular formed bracket. That would accomplish some of what the Air Force patent article (1979) was trying to accomplish. It would certainly act to resist any bending back of the main spar.
I’m no engineer, although I did stay at a Holiday Inn Express once, and I broke plenty of things on the farm as a kid, so I have some sense of how things fail structurally. I have the complete kit but will just be starting soon on the HS.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> It can be done easier than that-- Cessna uses a "mini-longeron" riveted lengthwise to the upper skin. Either looke at a parts manual or stop in at a wing shop. It's simple, light, and effective. Only takes a notch in the top of the rib to accommodate it.

Isn't that the same thing Vans does on the RV's?
