#CMT# #/CMT# The device has an acoustic exchanger (2) stepped from a submarine boat and connected with the boat by a message line i.e. energy transfer line (4). The exchanger accommodates a transmission unit i.e. acoustic transducer (8), while a receiving unit (9) i.e. hydrophone, is installed in the boat. The exchanger has an adjusting electronics, a power amplifier (7) and a cassette (6) for the message line, where the electronics and the amplifier are arranged outside of the transmission unit. The exchanger is coupled with the receiving unit, and has a loading and starting device (3). #CMT#USE : #/CMT# Device for repelling a torpedo engaged at a submarine boat. #CMT#ADVANTAGE : #/CMT# The exchanger accommodates the transmission unit i.e. acoustic transducer, while the receiving unit i.e. hydrophone, is installed at the submarine boat, thus receiving background noise of the submarine boat by the hydrophone and radiating the noise at a exchanger position, and hence ensuring sufficient decoupling between the transmission and receiving units of the acoustic exchanger. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a submarine boat. 2 : Acoustic exchanger 3 : Loading and starting device 4 : Energy transfer line 6 : Cassette 7 : Power amplifier 8 : Acoustic transducer 9 : Receiving part. |
