  • Publication number: 20230211861
    Abstract: Disclosed is a method and system to provide protection for maritime vessels from multiple threat types including shoulder launched rocket propelled threats, ballistic (howitzer), and larger scale missile systems. According to an exemplary embodiment, the protection system is based on the ballistic launch (from the protected vessel) of an explosive charge(s) aimed ˜5 meters away from the vessel and ˜1 meter beneath the waterline followed by detonation to enable the formation of a water wall. Through the formation of a water wall, incident threats can be initiated (piezo fuze), and passivated through dynamic interaction with the water formation. In addition, the upward velocity of the water wall can enable an upwards rotation of the incident threat changing the orientation of the warhead jet formation (for shape charge warheads) above the vessel.

  • Patent number: 11009318
    Abstract: A lightweight armor system providing blast protection and ballistic protection against small arms fire, suitable for use in helmets, personnel or vehicle protection, and other armor systems. A hard substrate is coated on the front surface with a thin elastomeric polymer layer, in which hollow ceramic or metal spheres are encapsulated. The coating layer having a thin elastomeric polymer layer with encapsulated metal or ceramic hollow spheres can be stand-alone blast protection, or can be added to an underlying structure. The glass transition temperature of the polymer is preferably between negative fifty Celsius and zero Celsius.

  • Publication number: 20070017359
    Abstract: A composite armor panel and method of manufacturing the same are disclosed. In one embodiment, a plurality of ceramic spheres are positioned in contact with an armor substrate. A polyurea layer is interposed between the plurality of ceramic spheres such that the polyurea layer partially encapsulates the plurality of ceramic spheres and bonds the plurality of ceramic spheres to the armor substrate. The plurality of ceramic spheres are partially exposed and oriented in a direction of anticipated impact.
