Design Blueprint: An Inflatable Habitat Pressure Shell: Hoop Stress, Bladder Thickness, Mass and Comparison with a Rigid Shell

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24145227): This paper presents a computed design for an inflatable pressure shell with a gas-retaining bladder, restraint layer and protective cover, sized from hoop stress at the operating pressure and compared on mass with a rigid aluminium shell of the same volume. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
