Abstract
A new method for silencing internal machinery generated torpedo noise is proposed. This innovative solution to the problem has the added capabilites of: controlling on a wavevector basis the acoustic signal radiated by the torpedo and simulation of boundary layer excitation on a torpedo hull. The proposed device thus offers the capability to not only suppress internally generated noise, but flow noise as well. The Phase I program encompasses an actuator design study, supported by an ongoing APTEK Navy Potential Contractor Program (NPCP) with NUWC. Also included is testing of a pro-prototype device on a simplified geometry, and a design proposal for a prototype actuator to be tested on an actual torpedo in Phase II.
