ABSTRACT:
A system for inducing turns in ram air canopy parachutes having a plurality of openings in the upper surface layer of the parachute canopy with the openings being equally distributed on opposite sides of the parachute centerline. Flaps are provided on the under side of the upper surface layer to close the openings. Control lines are attached to the flaps for selectively opening the flaps on one or the other side of the centerline to allow ram air to flow through the openings. This reduces lift and increases drag on one side of the ram air canopy parachute to induce a turn.
