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 spall liner including a first plurality of flexible fabric plies of a first dimension secured together and secured to a first tie layer of a second, larger dimension. At least a second plurality of flexible fabric plies are secured together and secured to a second tie layer. The first and second tie layers are secured together. A cover includes separable fastener structure of a first type for removeably securing the liner to the inside hull of a vehicle equipped with separable fastener structure of a second type.

Spall liner

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 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.

Vehicle and structure shield

Vehicle and structure shield method

An armor system and method for the interior of a structure to be protected wherein releasable fastener material is secured to an inside wall of the structure and at least a first armor panel includes, in one example, a spacer layer, a ceramic hard face layer behind the spacer layer, a ballistic material behind the ceramic energy absorber layer, an encapsulant about the spacer layer, the ceramic energy absorber layer, and the ballistic material. Releasable fastener material is on the encapsulant adjacent the spacer layer for mating the panel to the inside wall of the structure.

Armor system

Boring apparatus for forming a generally horizontal underground passage in soil for a utility conduit or the like that includes a tool head with a base portion and a nose portion mounted on the base portion. The base portion is rotatable relative to the nose portion between a first position in which nose portion surfaces are symmetrical with respect to the tool axis so that the tool will move along a straight path and a second position in which nose portion surfaces are in asymmetrical position with respect to the tool axis so that said tool will move along a curved path. By application of torque to the base portion, the base portion is shifted relative to the nose portion to shift the tool head from between an asymmetrical configuration and symmetrical configuration. Torque generating surface structure interacts with the soil and generates clockwise torque in one tool head position and counter clockwise torque in the other tool head position.

Guided mole

Boring apparatus for forming a generally horizontal underground passage for a utility conduit or the like that includes a tool head with elongated body structure and a cutting face of ellipto-conical form at one end of the elongated body structure. The cutting face has a major axis and a minor axis and cutting bit structure is fixed to and projects forwardly from the cutting face and extends substantially the full width of the cutting face generally along the major axis. The tool head also includes coupling structure for attaching the tool head to a drill string such that the cutting tool face is offset from the drill string axis. Structure in the cutting face defines a cutting fluid orifice adjacent the cutting bit structure for directing a high velocity jet of cutting fluid forwardly of the cutting tool face. The tool body is adapted to be advanced and concurrently driven in rotation to move the cutting face in orbital boring action about the drill string axis to bore an underground passage and to be advanced without rotation to produce a change in direction of the underground passage in the direction of offset from the drill string axis.
