A thruster assembly that in addition to propulsion provides water flow to/from compartments and systems on board a vessel. In a first position, the thruster assembly provides propulsion/steering. Pivoted to a second position, operation of the thruster in a first direction draws a flow into the vessel and in a second direction draws a flow out of the vessel. The flows may be conveyed to/from compartments/systems on board the vessel via conduits in communication with a chamber having an opening through which the thruster drives the flows. The flows may be used to submerge/surface the vessel, or to provide systems cooling or serve other functions. Pivoted to a third position the thruster assembly is retracted and enclosed within the chamber to form a hydrodynamically clean exterior.

An explicit integration algorithm for computations of discontinuous wave propagation in heterogeneous solids is presented, which is aimed at minimizing spurious oscillations when the wave fronts pass through several zones of different wave speeds. The essence of the present method is a combination of two wave capturing characteristics: a new integration formula that is obtained by pushforward-pullback operations in time designed to filter post-shock oscillations, and the central difference method that intrinsically filters front-shock oscillations. It is shown that a judicious combination of these two characteristics substantially reduces both spurious front-shock and post-shock oscillations. The performance of the new method is demonstrated as applied to wave propagation through a uniform bar with varying courant numbers, then to heterogeneous bars. © 2012 John Wiley & Sons, Ltd.

Variable stiffness fluidic flexible matrix composites (f 2mc) are investigated for vibration isolation through analysis and experiments. The fluidic flexible matrix composites are novel structures that have been shown to achieve significant changes in stiffness through simple valve control. The objective of this research is to develop analysis tools to investigate the f 2mc variable modulus system for semi-active vibration isolation and to validate the results through experiment. A nonlinear analytical model of an isolation mount based on the f2mc tube with a proportional valve is developed. Analysis results indicate that the f 2mc based isolation mount is effective for reducing the force transmitted to the foundation. Simulation studies demonstrate that the transmissibility ratio can be tuned via a proportional valve, where the resonant frequencies and damping can be regulated. Experimental results agree with analysis results and validate semi-active vibration isolation using a proportional valve. © 2011 SPIE.


A submersible vessel having wing and keel assemblies that are extendable for wind-powered surface operation and retractable to reduce drag for submerged operation or to place the vessel in a more compact configuration. A deployment mechanism including an actuator and linkage pivots the wing and keel assemblies simultaneously between the deployed and retracted configuration. The vessel may have first and second pressure hulls flanking the wing and keel assemblies. A drive mechanism including a motor and a gear train employing pulley-and-cable assemblies rotates either the wing and flap together such that the flap angle relative to the wing is constant, or to change the flap angle relative to the wing with the wing angle of incidence held constant. The invention also provides a retractable wind-powered propulsion apparatus that is mountable to the hull assembly of a submersible or non-submersible vessel.

In a three-day US Naval exercise that took place last month in Rhode Island's Narragansett Bay, Lockheed Martin achieved a world-first. It used an unmanned submersible to launch an unmanned aerial vehicle (UAV), while an unmanned surface vehicle provided surface reconnaissance and surveillance. The exercise began with Ocean Aero's Submaran surface vehicle relaying instructions from a ground control station to Lockheed Martin's Marlin MK2 autonomous underwater vehicle, via underwater acoustic communications. Acting on those instructions, the Marlin in turn released a canister containing the company's fixed-wing Vector Hawk UAV, with its wings folded back. Upon reaching the surface, that canister opened and the UAV unfolded its wings and took off, proceeding to follow a predetermined flight path. Propelled by either an electric thruster or a retractable wingsail, the 4.14-meter (13.6-ft) Submaran (seen below) is equipped with solar panels that allow it to remain operational for months at a time. It can be outfitted with a variety of sensors for different applications, and is even capable of submerging beneath the surface. The 10-ft (3-m) battery-powered Marlin can descend to up to 1,000 ft (305 m), cruising for up to 24 hours and managing a maximum payload of 250 lb (113 kg). The Vector Hawk, meanwhile, can remain airborne for over 70 minutes on one charge of its battery pack, and has a line-of-sight range of up to 15 km (9 miles).
