ABSTRACT:
A parachute apparatus with a main canopy having conventional suspension lines and load carrying means with a plurality of main loops attached with respect to the panels of the main canopy. A secondary canopy is positioned within the main inlet opening of the first canopy and is adapted to intially retain the lower edge of the main canopy in a closed position. The outer surface of the secondary canopy and the inner surface of the main loop canopy are connected by way of the main loops and by way of secondary loops located on the external surface of the secondary canopy. A retaining cord extends through the secondary loops and the main loops to reef the main canopy to the secondary canopy during the initial stages of inflation. During this time the secondary canopy will inflate and provide a controlled flow of inflation air into the main chute. Once the main parachute has become partially inflated then the reefing cord is cut allowing full inflation of the larger main canopy.
