Abstract
A barrel-stave projector that uses a rod of Terfenol-D for the driving element is described. Radial slots rather than laminations were used to control eddy currents in the Terfenol drive rod. The effectiveness of these slots was studied experimentally and by finite element modelling. The performance of a prototype barrel-stave projetor equipped with a radially slotted Terfenol driver was measured and is compared with the performance of a projector powered by PZT-4.
