| Abstract: | A code of towed cable-array system simulation was written according to a finite difference approximation. The code was improved with boundary condition taking rope drag on free end. Tow model cables were simulated to test the code validity. A practical towed cable-array system has been used to investigate behaviour on turning maneuvers. The results of the simulation shows that drop\|down phenomenon happened while turning angle velocity is under about 0.007 rad/s. |
