Re: February 2011 - Tell us what you've done this month! Mainly fiddled around with my "center section" and the loads on it, the part in my design that sees all forces (wing, landing gear and seat attachment). Played with Scan and Solve to check whether that's a viable way to analyze it. Not really, doesn't do orthotropic materials and doesn't to statically indeterminate parts. By doing so, I also got rid of several components and managed to design them as only two parts that incorporates all attachment points for the controls, seats, luggage part and landing gear/wing attachment. I also finally designed seats (composites) that reliably collapse in a crash, without nasty side-effects or exorbitant risks.
