Abstract

A buoy released from an aircraft for carrying out under water listening includes a balloon fixed to a body by way of a set of halyards extending from the top to the base of the balloon and fixed inside the neck of the body of the buoy. The inflation air penetrates into this neck then into the balloon through triangular openings formed in the neck. A textile sleeve fixed to the internal wall of the neck above the inflation openings turns inside out after impact on the water so as to close these openings, which avoids deflation of the balloon and loss of the buoy.
