  • Patent number: 10731604
    Abstract: A solid rocket motor includes a first solid propellant and a second solid propellant at least partially surrounding the first solid propellant. The second solid propellant is resistant to fragment impact and the first solid propellant has a higher impulse than the second solid propellant.
    Type: Grant

  • Publication number: 20120232189
    Abstract: A polymer adhesive includes a polymeric binder, optional reinforcing fibers dispersed through the polymer binder and solids dispersed in the polymeric binder. The solids are effective to cause decomposition of the polymer adhesive at a temperature between 200° F. and 500° F. with a generation of gaseous products at a predetermined temperature. One suitable composition includes siloxirane, graphite, glass beads, potassium nitrate, silver nitrate and lactose and decomposes at a temperature of about 318° F. The polymer adhesive may be used in the assembly of a housing for rocket motor or a warhead. Decomposition of the polymer adhesive when the housing is exposed to sufficient external heat to cause a rocket propellant or warhead explosive to decompose, referred to as cook-off, enables venting of the rocket propellant or warhead without uncontrolled destructive rupture of the housing.

  • Patent number: 7137340
    Abstract: The Mixed Mine Alternative (MMA) System is a military system designed for use in mechanized warfare. The MMA System has three components, MMA smart Antitank mines, MMA Antihandling Sensors linked to the MMA smart Antitank mines, and MMA Remote Control Units (RCU). The MMA smart Antitank (AT) mines contain a primary sensor system hardened against countermeasures and a kill mechanism similar to existing scatterable AT mines. The MMA AT mine is capable of transmit and receive communications with a Remote Control Unit and with the MMA Antihandling Sensors (AH). The communications capabilities and processors in the MMA AT and the MMA AH allow the system to establish MMA AT to MMA AH links after the mines have been scattered. MMA AT will be linked to MMA AH that are within their lethal radius. The MMA AT mine processors allow the mine primary antitank sensor to be on or off. The mine may receive and act on detonate instructions from the primary antitank sensor, from the antihandling sensors, or from the MMA RCU.

  • Patent number: 5198608
    Abstract: A mine clearing rake comprising a rake assembly with alternately disposed large and small teeth which are arranged to form a broad "V" and are rigidly supported laterally by horizontally disposed bars and rods to provide a maximum proportion of open space rearwardly and are supported rearwardly by a rigid reinforcing frame assembly which is attached to the bottom edge of the moldboard of a propelling vehicle, such as a tank, and have four additional points of support and/or attachment to the moldboard. An extension grid assembly is also mounted above the rake assembly to prevent unearthed mines from rolling over the mine clearing rake. A skid shoe assembly is attached to the reinforcing frame assembly and protrudes through the rake assembly so that the skid shoe rests upon the surface of the minefield during operation of the mine clearing rake.
