According to some embodiments, there is provided a ballistic-resistant composite including a plurality of large denier per filament (dpf) yarns. The large dpf yarns may have a “Composite-Armor dpf factor” (CA•dpf) of greater than or equal to 6.9.
摘要:
A marine vessel which includes a bow section, a stern section and a mid-section, wherein the bow and stern sections are of different hull construction from that of the mid-section which has a curved outer shape; the skin of the hull of the bow and stern sections are preferably made of hybrid composites while the port and starboard sides of the mid-section are of hybrid composites supported on the inside thereof by a light framing to transmit pressure loads; the mid-section further includes an inner section that may be of box beam construction or longitudinal bulkhead construction.

摘要:
THE HULL OF A MARINE VESSEL IS PROTECTED FROM FOULING BY MARINE GROWTHS BY A FOIL OF ANTI-FOULING METAL SUCH AS COPPER OR A COPPER ALLOY ADHESIVELY BONDED THROUGHOUT ITS AREA TO THE HULL BELOW THE WATER LINE. THE FOIL IS CONVENIENTLY APPLIED TO THE HULL BY PRESSURE SENSITIVE OR HEAT SENSITIVE ADHESIVE.
摘要:
An ultra-fast trimaran deep water and littoral naval ship suited to combat, search and rescue, and/or deployment operations has a plurality of semi-planing hulls connected to the underside of a deck in a trimaran configuration. Further, a plurality of propulsion stages including a cruise propulsion stage, a wind assisted propulsion stage, and a vectored direct thrust propulsion stage may be independently operated alone or in conjunction to propel the ship at various speeds suited to different situations.
摘要:
A floating unit comprising: a hull having a recess in which a deployable wall is mounted, the wall being movable between a first and a second position; wherein in the first position the wall is enclosed within the hull in the recess; and in the second position the wall at least partly protrudes from the hull, thereby defining a partly enclosed space; and wherein the floating unit further comprises means for supplying air bubbles to the partly enclosed space, the partly enclosed space being configured to constitute an underwater air pocket filled with air bubbles upon supplying the air bubbles from the means for supplying the air bubbles when the floating unit floats in the water with the wall in the second position.

Stabilizers (14.1, 14.2) coupled to associated stanchions (20.1, 20.2) and associated linkage assemblies (16.1, 16.2) on both sides of a central hull (12) provide for piercing or cutting through waves (76′). Aerodynamic surfaces (18.1, 18.2, 112, 114, 116, 118) over the linkage assemblies (16.1, 16.2) provide lift, as may a central keel (68) on the central hull (12). In one embodiment, each stanchion (20.1, 20.2) is coupled to the central hull (12) with a four-bar linkage assembly (16.1′, 16.2′) incorporating pivot bushings (78, 80, 86, 88, 92, 94, 98, 100) depending from the central hull (12) and the associated stanchion (20.1, 20.2) in cooperation with two pairs of non-parallel hinge pins (82.1, 82.2, 82.3, 82.4), respectively, with associated wedge-shaped aerodynamic surfaces (112′, 114′, 116′, 118′) attached to the linkage assembly (16.1, 16.2). The height of the stabilizers (14.1, 14.2) relative to the central hull (12) is adjustable using associated actuators (42.1, 42.2) in cooperation with the linkage assemblies (16.1, 16.2) either providing for, or responsive to, different operating conditions. Dampers (42′) may be associated with or incorporated in the actuators (42.1, 42.2) to provide for dampening associated shock and vibration.
