Abstract:

The underwater acoustic power of type BK Electrodynamic Transducers has yielded extraordinary reliable propagation ranges in the Pacific Basin. These tests have utilized the MOD 3B version described in NEL Report 1151. The MOD 3 Series built extensively of magnesium and with large internal air voids requires mass loading to even submerge and imposes need for unnecessarily large volume air compensation. The MOD 7 corrects these features and has other improvements. The smaller pistons however, reduce the radiated acoustic power at 20 cs and below.
