TOWED UNDERWATER VEHICLE EQUIPPED WITH HYDROACOUSTIC EQUIPMENT FOR SLUDGED OBJECTS AND PIPELINES Russian patent published in 2012 - IPC B63C11/48 B63G8/42 G01V1/38 

FIELD: transport.

SUBSTANCE: invention relates to underwater works for seafloor sounding in order to perform bottom shaping, pipeline laying-out with binding to geographical coordinates, revelling sludged objects. Towed underwater vehicle is equipped with hydroacoustic equipment and made as hollow cylindrical housing with removable head and tail fin, provided with penetrating device and equipped with parametrical profile recorder and control and computation module, and is connected with towing vessel by strength-power communications cable. Stabilising fin consists of two planes forming X-shaped structure. Penetrating device is made as horizontal wing and two vertical wings mounted on half-axles located in transversal plane relative to cylindrical housing. On the horizontal wing, towing assembly with sealed connector for strength-power communications cable attachment is installed. Here, hydrodynamic penetrator is installed. In the lower part of cylindrical housing in niche, crate with parametrical profile recorder elements attached to it is mounted. Hydroacoustic equipment includes parametrical profile recorder, consisting of emitting parametrical pumping antenna and receiving antenna, facilities for processing and recording hydroacoustic signals.

EFFECT: increased reliability of underwater objects detection due to higher accuracy of towed underwater vehicle orientation.
