Patent abstract

A hybrid drive (HD) multi-mode pipe projector (MMPP) for use in underwater acoustic applications is provided. The HD MMPP is formed with an inner magnetostrictive drive motor nested within an outer drive motor. The inner motor is surrounded by a magnetic field generating coil winding. Preferably the inner drive motor is a Terfenol-D motor and the outer drive motor is a radially-poled piezoceramic drive motor. This nested configuration provides increased bandwidth and low-frequency extension to the MMPP design.
