Inflatable Formwork with a Regolith-Covered Arch for Rapid Habitat Shielding Construction

This study sizes inflatable-formwork construction of a regolith-covered arch bay of 8 metre span and 12 metre length: the arch presents 151 square metres, a 1 metre cover requires 151 cubic metres, about 226 tonnes, of regolith, and the cover weight load of 2430 pascals under lunar gravity sits within the stated form pressure during placement. Sizing follows from computed regolith budgets derived in the study. This is a computed study with no targeting or weapon application. The work is simulated and computed from stated assumptions, not measured.
