Acoustic bulletin, Vol. 7 ¹ 3, (2004) |
| A model of direct-flow hydrodynamic projector formed by elastic flooded jet membrane is considered. A basic frequency of the acoustic signal is calculated as a function of geometrical and hydrodynamic parameters of the jet. Theoretical results are compared with the experimental ones. A criterion for the resulted model conformity to practical projectors of a given type is proposed. |
