Patent ID: 7611094

Claim:
A system for slowing an air vehicle, comprising an independently supported aerodynamic drag device, having a fabric sheet, and a frame system comprising: a) at least two upright support members; b) at least two elongated elements, each of said elongated elements having a direction of elongation, said elongated elements being disposed such that said directions of elongation are substantially parallel to each other, wherein said fabric sheet is slidably connected to said elongated elements substantially along a forward direction of travel of the air vehicle; and wherein said system for slowing an air vehicle is configured such that, after contact is made between the flying air vehicle and said aerodynamic drag device, at least part of said aerodynamic drag device is carried along by the air vehicle thereby decelerating the air vehicle, wherein a majority of a kinetic energy dissipation of a combination of the air vehicle and said aerodynamic drag device is due to an aerodynamic drag of said fabric sheet.
