description in fig1 and 2 the present invention is illustrated as applied to a two parachute cluster for purposes of illustration two twenty four gore canopies 10 12 are shown six gores 14 extending between a and d of each canopy are connected at a skirt portion 17 the skirt portion 17 of six pull down gores 18 of canopy 10 between c and d is adapted to be pulled down toward a confluence point 20 fig2 a typical length of pull down is about 10 of the canopy diameter a narrow slot opening 22 is disposed near a skirt hem 19 on six gores 24 extending from a to b directly opposite to the six pull down gores 18 the same modifications are made on canopy 12 as shown in fig1 referring to fig2 canopy pull down and release mechanisms 26 28 are shown attached to canopies 10 12 respectively when the six pull down gores 18 of canopy 10 are pulled down the inflated canopy 10 is deformed fig2 to create a high velocity air jet emerging from the opposite side of the canopy at gores 24 of canopy 10 the slot opening 22 near the skirt hem 19 enhances the jet effect the net result of the modifications is to provide a thrust which glides canopy.
