Abstract: The port security barrier includes multiple barrier float assemblies connected to one another to form a barrier to stop, delay and discourage attacks by high speed boats of sixty five feet or less in length on high valued waterfront assets such as ports and docking facilities. The port security barrier includes multiple barrier floats coupled to one another by flange connectors. Each barrier float assembly also has a capture nylon net which is used to capture the high speeds and prevent an intrusion into restricted waters.

Abstract: Aircraft comprising an airframe having a forward end, an aft end opposite the forward end, a top extending between the forward end and the aft end, and a bottom opposite the top side. The aircraft further includes a power plant mounted on the airframe. In addition, the aircraft includes at least two propellers rotatably mounted on the airframe and powered by the power plant for moving the aircraft in a generally forward direction during operation of the propellers. Also, the aircraft includes at least two counter-rotatable fan sets mounted on the airframe and powered by the power plant for providing upward lift to the aircraft during operation of the fan sets.

Abstract: A planetary gear system is provided where the sun and planet gears are of welded, one-piece double helical construction. Further provided is a method of forming a planetary gear system, and the sun and planet gears for such a system, by welding together two parts of the sun and planet gears, each part having helical gear teeth, to provide sun and planet gears of welded, one-piece double helical construction.

Abstract: A near shore port security barrier for protecting a vessel docked at a port facility from an incoming waterborne craft which is being used to inflict damage on the vessel. The near shore port security barrier consist of a plurality of floating barrier modules connected to one another and placed adjacent the hull of the vessel the near shore port security barrier is designed to protect. A wire mesh barrier fence, which is positioned on the outer perimeter of each floating barrier module is also provided to protect the vessel.

Abstract: A port security system comprising a continuous modular, floating barrier that is installed in lengths ranging from a few hundred feet to over a mile. The port security system is designed to stop high speed explosive laden waterborne craft traveling at speeds of fifty knots or greater from penetrating a military or commercial port. Each module of the port security system includes a capture net and net support structure which operates to stop the waterborne craft and prevent entry into the port.
