摘要： A spreader arm aperture generation system for use with a towed array is provided. The spreader arm aperture generation system broadly comprises a plurality of lines and a plurality of hydraulically activated, inflatable tubes for generating horizontal and vertical separation among the lines. Each of the tubes is filled with seawater to a desired pressure to achieve the desired horizontal and vertical line separation. Preferably, each of the tubes is formed from a high strength woven fabric.

摘要： A hydraulically activated device for spacing plural towed lines includes a toroidal and inflatable tube member defining an aperture in an opening of the toroid shape. A plurality of connectors each secure a corresponding one of the plural towed lines to the toroidal and inflatable tube member. The toroidal and inflatable tube member is inflated with sea water to a predetermined volumetric configuration suitable to an operating speed range of the towed lines and upon inflation will space the towed lines in a three-dimensional arrangement therearound. A sheath may also be formed around the toroidal and inflatable tube member, the sheath being formed in cross section as a tear drop or similar streamlined shape.

摘要： There is disclosed a method for determining damping coefficients, the met including the steps of providing a damper assembly including a bar of known parameters, and a viscous damper, wherein a first end of the bar is disposed in the viscous damper while the second end of the bar is free, applying a known force to the second end of the bar in a direction toward the first end of the bar, measuring the response function of the assembly, comprising the ratio of the bar acceleration to the applied force, determining the eigenvalues of the response function, and from the eigenvalues computing the damping coefficient of the damper assembly.
