Default Re: On designing airships

Hi Tony

I'm actually Dyscalculic so Prosteel is invaluable, use it to work out end reactions by popping simple moments into a beam and reading off the results

It's quite handy for working out what bending happens to an airframe in a drop-test. Take a simple weightshift trike and work out what height it fell from and how much the suspension and tyre squishes, and you get the 'G' load on it, input the load positions and the keel bending is in the result. As the Young's Modulus is three times that of steel you can get a rough approximation of the amount the airframe bends.

This got results that had been missed by a Doctor in Aeronautics on a suspension design, great fun to do.
