DEVICE FOR AUTOMATIC CONTROL OF BUOYANCY, HEEL, TRIM, DEPTH AND ALTITUDE IN SUBMERSIBLE VEHICLES

摘要

The present device falls within solutions of motion and equilibrium control of submersible vehicles, namely in terms of heel, trim, depth and altitude. An embodiment comprises 3 or more flexible buoys or tanks of liquid ballast, each one with an air inlet valve and an air outlet valve, with electrically controlled opening and closing; an electronic control unit for independent opening and closing of the air inlet and outlet valves of the tanks of liquid ballast; a reservoir for storing compressed air connected to the air inlet valves of the tanks of liquid ballast; wherein said tanks of liquid ballast comprise a free communication with the exterior of the tank via one or more holes placed on the inferior part of the tank. The solution considerably reduces size and weight of the equipment and improves manoeuvrability of the vehicle.
