Abstract : A method is presented for arranging filamentary, load bearing material to approximate a constant stress condition in the gas envelope of a free floating balloon for the purpose of maximizing structural efficiency. A relation between material distribution and envelope stress was obtained. Manufacturing equipment was developed and a natural shape, zero pressure constant stress balloon was fabricated and tested.
