Marine waterjet recently was introduced as potential prime mover for smaller naval craft; underwater noise producing characteristics of these jets have been investigated by U S Naval Engineering Experiment Station and compared with those of standard propeller driven unit; waterjet unit investigated was axial type pump coupled directly to standard 6-cyl gasoline fueled marine engine rated at 100 hp; differences in type of noise, noise spectra, etc, are reported; based on 20 db difference between 2 power drives, indications are that conventional propeller craft could be detected at distance 10 times farther away than waterjet; applications are noted. Reprinted from BuShips J Aug 1963.
