  • Patent number: 8171986
    Abstract: An apparatus includes a foam metal panel heat exchanger core positioned in a duct, an inlet flow passage for directing a first fluid to the heat exchanger core, and an exit flow passage for directing the first fluid from the heat exchanger core, wherein the inlet flow passage is tapered relative to an inlet face of the heat exchanger core and the exit flow passage is tapered relative to an outlet face of the heat exchanger core. The first fluid has a substantially uniform flow distribution through the core. The inlet and exit flow passages can be adjacent to each other. The core can be formed of a compressed foam.

  • Patent number: 7623059
    Abstract: A disruptive media dispersal system for aircraft which absorbs and scatters directed energy weapon beams such as tracking lasers and high energy lasers (HELs) is disclosed. The system may include laser detectors, laser beam propagation disruptive media and a dispersal system. When attacked by a directed energy weapon such as a laser, the laser detector system or vehicle operator deploys the disruptive media. The disruptive media is released by a feeder and dispersal system into the air in the path of the tracking and/or HEL weapon. For example, the dispersal system may be located onboard the aircraft near the front of the fuselage.

  • Patent number: 7132166
    Abstract: An embodiment of the present invention provides a protective layer which includes an aggregate of long chain molecules wherein each long chain molecule is randomly oriented and consistently entangled to adjacent long chain molecules throughout the aggregate of long chain molecules. Additionally, the layer is essentially free from voids and essentially free from residual stresses. By way of example and not limitation, the long chain molecule may be a plastic or liquid crystal polymer. Additionally, a method for forming the protective layer is disclosed herein.
