  Abstract

The dynamic pressure differential changes the microstructure of fabric and therefore affects air permeability, which determines the performance of parachutes. In this paper, the dynamic air permeability of different weaves is investigated numerically. The weave structures are modeled in three-dimensional microscopic view, and the obtained air permeability agrees well with the experimental results. The influence of the fabrics mechanical properties on air permeability is then studied. The main parameters include Poisson’s ratio, Young’s modulus and compression coefficient. Results show that Poisson's ratio of yarn is a significant factor of air permeability, while Young's modulus is a negligible factor. The effect of the compression coefficient on air permeability depends on weaving and porosity. The compression coefficient affects the air permeability through the variation of three microstructure parameters: fabric thickness, yarn width, and yarn spacing, while the Poisson's ratio affects yarn width. The results can contribute to the design of inflatable space applications and increase the accuracy of their performance analysis.
