Abstract

A structure or vehicle protection method including a removable frame on the structure or vehicle, and a net within the frame and spaced from the structure or vehicle and having a mesh size designed to disarm an incoming threat.

Claims

1. A method of defeating an RPG, the method comprising:

attaching a frame to a vehicle or structure in a spaced relationship with respect to the vehicle or structure;

attaching a net made of synthetic line to the frame, the net having a mesh size and configured such that when an RPG ogive impacts the net, the net material collapses the RPG ogive duding the RPG; and

whereby when an RPG impacts the net material, the net material collapses the RPG ogive duding the RPG.

2. The method of claim 1 in which a net mesh size between 30-60 mm is chosen.

3. The method of claim 1 in which a knotless weave of the line is chosen.

4. The method of claim 1 in which the line is made of PBO material.

5. The method of claim 1 in which the net line diameter is between 0.5-3 mm.

6. The method of claim 1 including attaching two or more nets on the frame.

7. The method of claim 6 in which there is at least a first layer of smaller diameter line material and a layer of larger diameter line material.

8. The method of claim 7 in which there are between 2-4 layers of smaller diameter line material over a single layer of larger diameter line material.

9. The method of claim 1 in which the net frame is attached between 8″
