ABSTRACT:
A parachute device primarily for propulsion of a work load, specifically a snow skier who wants to go across flat terrain or uphill, has a canopy with a leading annulus and a normally open apex vent having a plurality of wedge shaped panels secured on one side to the annulus, each panel has a tip with an apex ring, a plurality of suspension lines lead from the annulus to a control center, a vent control line extends from the control center to each panel apex ring and the control line has a vent control ring which causes the control line to pull the panel apex rings together in an apex of the canopy, the control center has a motor driven reel for taking in the control line and a one-way brake on the reel enables letting out of the control line when a manual brake release is manipulated, a safety release in one side of the control center has structure for release of a fraction of the suspension lines for instant deflation of the canopy and a complete release system on a load harness has structure for instant complete release of the canopy and control center from the work load. A method of varying the output of a normally open and vented parachute has the steps of inflating the canopy while the vent is open, then incrementally closing the vent to get the desired output from the canopy, and taking up a control line used to close the vent, the control line is held tauntly so that the vent cannot reopen until the control line is released, these steps may be used for propulsion of a snow skier up a hill with a parachute device.
