Abstract

Abstract

To study the initial trajectory of a wire-guided torpedo launched by a battery-activated outside tube, hydrodynamic theory was used to analyze the dynamics of the torpedo when sailing outside the tube. Subsequently, a dynamic model of the torpedo movement in the vertical plane was built based on the dynamic equations of the torpedo and characteristics of a wire-guided torpedo. The initial trajectory of the longitudinal plane of the torpedo at different values of rail control rudder angle and tube speed was simulated. The horizontal distance and depth difference between the torpedo and launch boat, torpedo pitch angle, and speed were all obtained before power battery activation; thereafter, the simulation data were analyzed. The results show that the above two parameters influence the initial trajectory and navigation attitude of the wire-guided torpedo. A safe initial trajectory and good attitude control were achieved by setting the rail control rudder angle, improving the tube speed, and verifying the feasibility of the launch method.
