Abstract
A parachute pack of the type including a pilot chute for drawing a main parachute canopy out of its container uses a single adjustable tension retainer cord and pin which holds a compression spring for the pilot chute in an adjustably tensioned state. Various packing methods and canopy sizes may be used with the pack so that a constant tension may be placed on the compression spring regardless of the thickness of the pack. In addition, ends of side flaps of the container are attached to the bottom flap of the container, and epaulet flaps are fastened to a top flap, to form a boxlike enclosure for the main parachute so as restrict release of the main parachute from the container until after the pilot chute has attained a sufficient amount of positive drag to urge the main chute therefrom.
