N2 - Micro- and macro-mechanics of parachute fabrics under a flow-induced pressure differential are studied using synchronous digital image correlation, microscopy, and permeability testing. Results are presented for a nylon textile commonly used in parachute systems, MIL-C-7020H Type III. The textile is subjected to a sequence of steady and stepwise incremental pressure differentials. Measurements resolve the pressure-dependent permeability and effective porosity of the textile, and the time and load-rate dependent response of sample deformation. It is hown that pore opening is negligible in the range of pressures studied.
