Hydraulic Component Acoustic Compatibility Study
1979
Shimamoto, M. S.
The Remote Unmanned Work System (RUWS) is a cable-tethered, unmanned work vehicle capable of performing deep ocean search, inspection and work tasks to depths of 20,000 feet. The vehicle and primary cable termination are open frame structures; thus, hydraulic components are located directly in seawater. Since the submersibles generally require simultaneous use of their propulsive capability and acoustic sensors such as sonar, the acoustic noise of the equipment must be low so that performance of the acoustic sensors is not degraded. This document reports the investigation of acoustic noise outputs off- the-shelf hydraulic components for use aboard RUWS.
