Abstract
The ram air parachute has restrictions on the inlets to the cells to reduce drag during flight and to reduce opening forces. The restrictions include triangular sections blocking portions of the inlets. The triangular sections may be positioned at loaded and non-loaded ribs. Furthermore, the triangular sections are dimensioned to tension the top skin between the loaded ribs and non-loaded ribs to preserve an aerodynamic shape during flight without cross-bracing. The loaded ribs may be shortened to create a zig-zag pattern at the front edge of the bottom skin for improved deployment with reduce drag during flight.
