Hey fellas,
When I retired in 2020, I had been a manufacturing engineer at Meggitt Airframe Systems for just shy of 10 years. Since the 1930's we have built crashworthy fuel cells for everything from B-29's to cruise missiles. I have personally watched over 50 drop-tests from our city water tower converted to a certified failure test rig. High frame rate, stroboscopic performance evaluation, and old fashioned cardboard with sugar release were some things I was involved in. It seems to me that a thin neoprene bladder with a couple of layers of glass cloth at 90 degrees would pass a 50' drop with 80%x15 gallons in it. I was not a product development engineer but I was close enough to the daily ply layups, that I feel there's people on this forum that have enough rubber experience to figure it all out.
