Abstract
A nose cone for attachment to an underwater vehicle for shielding a sonar ray in a nose portion of the vehicle from acoustic pressures in a water environment, the nose cone comprising a tubular body for surrounding side wall portions of the vehicle nose portion, a cap fixed to one end of the nose cone body for overlying a forward-most portion of the vehicle nose portion, and bleed tubes extending through the body and/or cap for permitting air to escape from between the vehicle nose portion and the nose cone when the nose cone is placed on the vehicle nose portion. There is further contemplated a method for acoustically shielding sonar arrays in nose portions of underwater vehicles, which includes utilization of the aforementioned nose cone.
