Development of Stretch Fabric for Parachute Canopies

Abstract

A new lightweight one-way stretch parachute canopy fabric was developed for use in personnel parachutes, whose mechanical properties are equal to the conventional 1.1 oz/sq yd canopy fabric, but which shows a greatly increased air permeability under the loading conditions experienced during deployment. The variation of permeability with pressure differential for a range of biaxial loading conditions was investigated for the new fabric and for other canopy fabrics, and it was shown that for maximum effectiveness the easy stretch direction of the new fabric should be oriented parallel to the direction of maximum stress in the parachute canopy.
