ABSTRACT:
A bladder shaped to conform to the form of the sonar transducer housing of a torpedo in which it is located compensates for volume changes because of temperature changes of the oil which fills the transducer housing. The bladder also compensates for the change in water pressure produced by the depth at which the torpedo is operating. The bladder is sufficiently stiff so that it maintains a predetermined shape substantially midway between its fully extended and fully compressed position during the time that the housing is air evacuated and then filled with oil at near atmospheric pressure. The bladder is thus capable of expanding or contracting to accommodate changes in the volume of the contained oil as the temperature of the oil changes. The bladder is preferably made of a material without substantial spring force or stretch.
