Abstract:
A pressure stabilized air transport vehicle having:a) a hull envelop including skin fabric crack propagation resistant means;b) said air transport vehicle including gas pressure maintaining means;c) said hull envelop skin fabric being of stiff and creep resistant material;d) said crack propagation resistant means including spaced bands encircling and running lengthwise of said hull envelop skin fabric and secured to said hull envelop skin fabric and forming interconnected polygons covering substantially the entire hull envelop skin fabric;e) said bands having poor creep resistance and high tensile strength;f) said polygons not exceeding about 10 feet in length and width;g) whereby when a crack develops in said hull envelop skin fabric within at least one polygon, said bands of said polygon will limit propagation of the crack permitting the gas pressure maintaining means to maintain a stabilizing pressure in said hull envelop.
