Latest Patents

Liszka holds a patent for a "Low drag body conformal acoustic array." This invention features a plurality of transducers that closely conform to the surface of a low-drag nose. The transducers are baffle mounted in close pack configurations to eliminate grating lobes. The baffle assembly is strategically mounted outside a pressure hull within a thin acoustically transparent fairing. Additionally, a plurality of pressure compensators are attached outside the pressure hull. The cavity between the pressure hull and fairing is filled with pressure compensating acoustic fluid. Larger portions of unused volume are first filled with a syntactic foam to minimize the amount of fluid required. The pressure compensators balance fluid pressure against external sea pressure to prevent fairing collapse. This array maximizes available nearby internal nose volume, allowing beamforming electronics to be located within the pressure hull in close proximity to the array elements, connecting via a plurality of short coaxial cables. The increased surface area of a conformal array permits the use of a greater number of transducers, resulting in a wide aperture and a narrower beamwidth than is possible with a planar array. This array has the capability of steering a beam forward, backward, and to the side with little variation in beam sensitivity. When scanning forward along the torpedo axis, it projects a larger aperture forward than planar configurations.
