1. A flexible projectile arresting device comprising:

  • (a) a plurality of essentially vertical side panels of flexible two-dimensional material, said side panels being arranged contiguously in plan with vertical edges of adjacent said side panels attached continuously to one another at panel intersections and with lower edges of said side panels lying in a common horizontal ground plane; and

    means of attachment therefor;

    (b) inclined compression struts of rigid linear material at each said intersection, the lower end of said inclined compression strut located in said ground plane, the upper end of said inclined compression strut located at the upper end of said intersection, said inclined compression strut making an angle with the vertical;

    (c) tension guys of flexible linear material attached to each said inclined compression strut, said tension guy being attached to and extending from the ground plane to the upper end of said inclined compression strut, said tension guy making an angle with the vertical greater than that of said inclined compression strut; and

    means of attachment therefor;

    (d) draped tension reinforcement of flexible linear material located continuously along and attached to the upper edges of each said side panel, said draped tension reinforcement being supported at each said panel intersection by attachment to the upper end of said inclined compression strut and following an essentially parabolic curve between adjacent said inclined compression struts; and

    means of attachment therefor;

    whereby the kinetic energy of a projectile impacting said flexible projectile arresting device is transferred and dissipated, without high energy rebound of said projectile and with said flexible projectile arresting device returning to its original position after impact.
