ABSTRACT:
A high performance ram air canopy for a parachute comprises a fabric structure including a top fabric element and a bottom fabric element, these two elements being held in a spaced configuration by two side elements and a plurality of intermediate partition elements. The elements forming the fabric structure define a plurality of cells that extend rearwardly from an open, substantially linear, front face of the structure, with the canopy in its deployed configuration and the cells filled with air. A canopy of this type is exposed to an excessive opening shock upon deployment and this problem is overcome by reducing the rate at which the cells can be filled with air upon deployment.
