A rocket propelled grenade shield including a flexible net and a frame secured to the flexible net supporting the flexible net. Spaced hard points are attached to the net, the hard points including a base portion with a cavity therein and a plug received in said cavity locking each hard point to the flexible net.

RPG defeat method and system

A vehicle and structure shield includes an array of hard points laterally spaced and outwardly supported, in one example, by a net subsystem and frame.

A shield system for an ordnance includes a frame and a flexible net subsystem supported by the frame. Diagonal lines of net material intersect at nodes forming diamond shaped mesh openings and a hard point is attached to at least select nodes.

Load sharing hard point net

A protection system includes a net made of flexible, low breaking strength intersecting lines connected at nodes. A frame supports the net and spaces the net from a vehicle and/or structure. Hard points are disposed at least at select net nodes and feature a multi-sided body with a cavity therein behind a front face thereof. The body includes a lip extending into the cavity. A protrusion extends outwardly from the front face. A tapered plug is received in the cavity and includes a ledge engaged by the lip locking the plug and a net node in the cavity and securing the hard point to the net node in a pivotable fashion.

Vehicle and structure shield with improved hard points

A method of designing an RPG. A computerized model is created of a shield mesh opening with lines of a net intersecting at nodes and with hard points positioned at least at select nodes. The effectiveness of the mesh opening at a plurality of obliquity angles is determined. In the model, a change is made to the size of the mesh opening and the effectiveness is determined again at a plurality of different obliquity angles. Iterations of this process allow an optimal mesh opening size to be determined for a threat such as an RPG.

Method of designing an RPG shield

A vehicle and structure shield hard point includes a forward facing base portion defined by a front face, sidewalls extending rearward from the front face including slots therethrough for the cords of a net, and a cavity surrounded by the sidewalls. A plug is sized to be frictionally received in the cavity of the forward facing base portion locking the cords of the net with respect to the forward facing base portion.

Vehicle and structure shield hard point

A surrogate RPG includes a warhead with an outer conductive portion and an inner conductive portion spaced from the outer conductive portion. A sabot includes an electrical circuit configured to monitor conductivity between the inner and outer conductive portions. The surrogate RPG can be used to test the effectiveness of various RPG defeat technologies.

Surrogate RPG

A shield system for an ordnance having a fuse sensitivity includes a frame and a flexible net subsystem supported by the frame. Chords of net material intersect at nodes forming mesh openings and a hard point is attached to at least select nodes. The net material has a breaking strength such that a chord will break upon impact of an ordnance fuse with the chord for a predetermined percentage (e.g., 100%) of ordnance fuse impacts.

Low breaking strength vehicle and structure shield net/frame arrangement

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.
