    摘要： For use with towable airfoils used to supply lift to a towed rider to assist with jumping in sports and recreation, a handle system having one or more control lines for coupling to the airfoil, and a line for coupling the handle to a tow vehicle, the one or more control lines and line for coupling to the tow vehicle being coupled together by a tension translation mechanism that divides the tension from the line for the tow vehicle to the one or more control lines by a predetermined factor, which typically would be other than 1:1. The handle system may further include an engagement mechanism for engaging the one or more control lines to lock or brake a line.

    摘要： A parachute has its suspension lines divided into groups, each group connected to the load through a linear actuator. During descent of the parachute, foreshortening of an actuator or of any group of adjacent actuators causes the parachute trajectory to move in the direction of the foreshortened actuator. Multiple parachutes connected to a single load, with each parachute being connected to the load through an actuator, can similarly have their trajectory controlled. The trajectory of the parachute can also be changed by a system of normally foreshortened actuators which lengthen by actuation. Simultaneous, rapid shortening of all actuators just before ground impact can be used to reduce the descent velocity at ground impact.

    摘要： The multi-cell canopy of the gliding wing type comprises an upper wall and a lower wall interconnected by ribs forming partition wall defining parallel cells open on the leading edge of the wing. Parachute control lines are secured to the trailing edge for deforming a part of the latter which forms a plain flap. The canopy comprises in its upper wall at least one air outlet passage which has the shape of a rearwardly facing slot so as to direct a laminar current of air tangentially of the upper wall.

    摘要： A maneuverable, ram air inflated, flexible aerial wing includes a plurality of adjacent, forward facing air cells having first openings along the leading edge thereof and a control surface extending between the aforesaid cells and the trailing edge. Generally rectangular in overall shape the cells are of such size and so positioned, and include rearward facing second openings, as to displace the separation point of the relative airflow across the upper surface further toward the trailing edge than with known devices, and which therefore achieves a higher lift to drag ratio. Further, the control line system and a series of rear vents combine to reduce the force required to lower the surface and help prevent erratic flight.

    摘要： An annular spinning parachute is composed of an annular canopy symmetrical about an apex, suspension lines of substantially the same length and interconnected together at the canopy apex and extending radially outwardly therefrom across the canopy and downwardly therefrom for coupling to an object supported by the parachute, and centerlines interconnected with the suspension lines at the canopy apex and extending downwardly therefrom for coupling to the object supported by the parachute. The annular canopy includes fabric panels each having a generally trapezoidal shape defined by a pair of opposing inner and outer borders with the outer border being greater length than the inner border and a pair of opposing side borders of substantially the same length. The annular canopy also includes inner and outer lateral bands respectively extending along and connected to the inner and outer borders of the fabric panels so as to dispose the panels in circumferentially spaced relation with respect to one another upon inflation of the canopy. The inner and outer bands and spaced panels define a central opening in the canopy having thhe canopy apex at the center of the opening and a plurality of exhaust vents arranged in alternating relation with the panels between the side borders of adjacent pairs of the panels.
