Abstract: A structural finite element model representing a novel inflatable airlock concept has been calibrated using full-scale test data. The concept, denoted as the Non-Axisymmetric Inflatable Pressure Structure (NAIPS), was developed under NASA’s Minimalistic Advanced Softgoods Hatch (MASH) Program. The current studies extended previous numerical efforts by incorporating the midbody section of the NAIPS to the dome section and calibrating the model with test data using a process that included surro…
