Vehicle and structure shield
A vehicle and structure shield includes a flexible net subsystem including an array of rods or hard points supported by the net subsystem and configured to impact a projectile striking the net. A frame includes mounting brackets attached thereto positioning the frame in a spaced relationship with respect to the vehicle or structure. A first releasable fastener subsystem releasably secures the net subsystem to the frame and a second releasable fastener subsystem releasably secures the mounting brackets of the frame to a vehicle or structure.
1. A vehicle and structure shield comprising:
a flexible compliant net subsystem with strands designed to break if struck by a projectile;
an array of hard points on the net subsystem, the hard points designed and attached to the net subsystem in such a manner that the hard points tumble and angle inwardly digging into an ogive of a projectile striking the shield;
a frame including mounting brackets attached thereto positioning the frame in a spaced relationship with respect to a vehicle or structure; and
the net subsystem secured to the frame.
2. The shield of claim 1 in which the net subsystem includes first and second spaced nets having nodes interconnected by the hard points.
3. The shield of claim 2 in which each hard point includes a base portion with castellations for the first net and a post portion extending from the base portion and including castellations for the second net.
4. The shield of claim 1 in which the net subsystem includes a single net and the hard points each include a post portion and a base portion with a cavity receiving the post portion therein.
5. The shield of claim 1 in which said hard points include a multi-sided portion defining sharp corners.
6. The shield of claim 5 in which each hard point includes at least five sides and five sharp corners.
7. The shield of claim 5 in which the multi-sided portion includes a cavity frictionally receiving a plug therein.
8. The shield of claim 5 in which the multi-sided portion includes a wall with longitudinal slots therein for strands of the net.
9. The shield of claim 1 in which the frame includes telescoping members.
10. The shield of claim 1 further including fasteners on the frame and corresponding fasteners on the periphery of the net.
11. The shield of claim 1 in which the hard points weight between 10 to 40 grams, are between ½ inch to ¾ inches across, between ½ inch to 1 inch tall, and are multi-sided.
