Research abstract
Applied Physical Sciences will develop a sound projector to support acoustic communication for submarines operating at tactical depths and speeds. The projector will have a nominal bandwidth and submergence depth rating of nominally 150 to 300 Hz and 1 km, respectively. System concepts that compare and contrast a single, stand-alone projector versus multiple projectors in an array format will be assessed. Analysis will also be performed to evaluate the utility of singly and doubly resonant projectors for each of the system concepts under consideration. Lumped parameter electro-mechanical-acoustical circuit models and finite element models will be used to evaluate the performance of each projector concept. Together with system-wide sonar analysis, a projector design will be down-selected and a quarter-scale prototype will be fabricated and tested.
