Implementation of a Physics-Scaling Propulsor Noise Model

Abstract

A Naval Undersea Warfare Center Division, Newport, RI, physics- scaling, broadband radiated noise model has been implemented for use in the design and analysis of weapon propulsors. For over 20 years, experiments have been performed in an attempt to isolate the contribution of the propulsor to the radiated noise signature of underwater vehicles. The focus of this effort was to bring more sophisticated hydroacoustic computational tools on line to supplement the experimental efforts of the Closed-Cycle ADCAP Propulsion System (CCAPS) special Initiatives Assessment (SIA) program. The most recent version of the computational tool is known as program BBN2. Described herein is the implementation of program BBN2 from the initiation of the CCAPS SIA effort through the most recent analyses.
