Pietenpol-List:Stress analysis

[matronics]

Original Posted By: Kip & Beth Gardner
I'm new to the list and have looked at the archive and couldn't findanything. Does anyone have a copy of a stress analysis that has been doneon the wood or steel tube Pietenpol? I understand one was done before thefirst one was built in England but have come up dry on finding someone witha copy. I'm an engineer and really don't want to repeat something that isalready done. The drawings look like a Pietenpol could be used as ahuricane tracker (put a sandwich bag over the mag?) but I would really liketo see where the weakest links are (and the strongest).Hank JarrettTwo Taylorcrafts, but want something open cockpit________________________________________________________________________________Date: Wed, 2 Jul 2003 20:56:33 -0400

Hank, if you're an engineer I'd say do it yourself. I did it for mine, butit wouldn't do anyone else any good because of the changes I've made(centersection 6" wider than plans, fuselage 1" wider than plans, etc.)What I found for my airplane with my changes was it was good for about 5 g'sultimate, so with a safety factor, it's a good 3.2 g normal categoryaircraft, but no more. I would not recommend any but the mildest aerobatics(the occasional wingover) in it.Jack Phillips, PE -----Original Message-----
