SELF-PROPELLED SIMULATOR OF SUBMARINE Russian patent published in 1994 - IPC

FIELD: hydroacoustic countermeasures. SUBSTANCE: self-propelled simulator of submarine has body with propelling device, control block and means of hydroacoustic countermeasures, system of propelling device noises compensation in chosen direction, that is made in the form of cylindrical surface radially fitting, mounted coaxially to longitudinal axis of symmetry, located on its covered with sound absorbing layer inner surface N receivers, placed on outer surface radially relatively to the receivers N emitters and N-channelled block of propelling device noises compensation. Each pair of radially located receivers-emitters is connected with corresponding channel of propelling device noises compensation block, each of which is electrically connected with control block.
