Abstract
An acoustic projector which includes an outer shell (8) formed of a reinforced epoxy resin having a longitudinal slot (14) has an inner reinforcing liner (20) formed of metal to reduce stress. The liner (20) extends throughout the length of the outer shell and has a longitudinal slot (22) aligned with the slot (14) formed in the shell (8). An arcuate shaped driver (10) is mounted along a portion of the I.D. of the metal liner (20) and separated therefrom by insulation (24).
Claims15
An underwater acoustic projector comprising an outer shell formed of a graphite/epoxy material including wound resin impregnated graphite strips, an inner concentric acoustic driver, and an inner concentric insulative layer, a metallic liner located between the outer shell and insulative layer, and a longitudinal slot formed in the outer shell, metallic liner and driver.
An acoustic projector comprising
- an outer cylindrical shell having an I.D. formed of wound resin impregnated graphite strips;
- a metallic liner concentrically mounted within the shell and extending along a portion of the I.D. of the outer shell to provide structural reinforcement thereto:
- a driver mounted within the metallic liner;
- and
- insulation separating the driver from the metallic liner.
