Abstract
A ram air parachute of the present invention includes specific cross porting of the ribs between certain cells to create a two-stage or multi-stage deployment. Cross ports between certain sets of cells have reduced or no conductance. In this manner, the center cells of the canopy open first, slowing decent, before the outer cells. The staged deployment reduces the opening forces on the pilot particularly in high speed flights.
