FIELD: weapons and ammunition. ^ SUBSTANCE: torpedo includes thermal engine, hollow shaft with noise silencer, whistle, self-guidance microphones and electric suppression filters. Whistle is put on end of silencer after propeller. Whistle provides the possibility for exhaust gas to pass through it with reduce noise level. Self-guidance microphones have the possibility of conversion of acoustic radiation to sound signals. Electric suppression filters have the possibility of passing only ship-target noise signals. ^ EFFECT: increasing sensitivity of torpedo self-guidance system. ^ 5 dwg |
