Underwater Drag Body

Introduction   

Underwater drag body dragged by towing the platform from the drag, when towing, in the hydrodynamic, gravity and buoyancy under the combined effect of maintaining the ideal towing posture and drag position, through its load sensors and functional components to complete the corresponding function. At the same time, through the underwater towing cable can also drag the cable to maintain the ideal posture or shape, by dragging the cable carrying sensors and functional components to complete the corresponding functions, such as the depth of the device and the expander belongs to this type of underwater drag body.

Main technical indicators are as follows:

         (1) fixed depth : 0 ~ 1000m;
         (2) depth control accuracy : better than 5m;
         (3) the depth of fluctuation range : less than ± 1m;
         (4) attitude to maintain the ability to : roll less than ± 3 °, pitch less than ± 2 °, pendulum less than ± 2 °;
         (5) posture swing period : ≥ 20s;
         (6) Speed adaptation range : 0 ~ 20kn.
