BOTTOM DRAG-RESISTANT SELF-CONTAINED HYDROACOUSTIC MODULE Russian patent published in 2013 - IPC G01S15/00 G01S3/80 G01V1/38 

FIELD: physics.

SUBSTANCE: disclosed is a bottom drag-resistant self-contained hydroacoustic module which is fitted with subsystems and devices which are placed in the housing of the bottom module and on the conducting rope of a vertical hydroacoustic antenna and facilitate operation of the module. On the conducting rope of the hydroacoustic antenna there is a float, hydrophones, a transceiving unit for acoustic underwater communication. In the housing of the bottom part of the module there is a subsystem for collecting and preprocessing information from all sensors mounted on the vertical antenna, a subsystem of geographic coordinates of the module. Drag-resistance of bottom self-contained hydroacoustic module is provided by that the housing of the bottom part of the module consists of two flattened cones. The bottom flattened cone faces the mud line with its large base and the small base is mated with the top flattened cone and has a surface inclination angle of 30-40 degrees. The top flattened cone is mated with the bottom cone by its large base and has a surface inclination angle of 10-20 degrees.

EFFECT: providing stable drag-resistance of the hydroacoustic module.
