Instrumentation and Equipment Upgrades to Improve Acoustical and Fluid Dynamic Measurements in the Garfield Thomas Water Tunnel

Abstract

The overall objective of the project was to plan and implement the necessary Garfield Thomas Water Tunnel mechanical, electrical, and instrumentation upgrades to support R&D for the next generation platforms and propulsors. However, in order to appropriately assess designs intended to meet the future hydrodynamic and acoustic goals, additional improvements in tunnel quieting and unsteady flow and acoustic signal processing were required. In addition, improved accuracy and resolution were needed for validation of design tools that will allow "out of the box" design tradeoffs at the small computational resolutions necessary for acoustics. This report describes the systems acquired under the grant.
