GTWT Flow-through Anechoic Chamber Design.

Abstract

Preliminary cost figures are presented to provide estimates of the funding required to complete the flow through anechoic chamber at the Garfield Thomas Water Tunnel. Information necessary to obtain these estimates required major decisions on the philosophy of design and operation of the chamber. Plenum wall details were discussed with the scientist who performed tests of a 1/6 scale model of the chamber for his Master's degree in architectural engineering. This report describes the construction details and turbulence control measures that resulted from these discussions. The total cost to complete the anechoic chamber test facility is estimated to be approximately $330K. This figure does not include cost of instrumentation or signal processing equipment. Appendix A describes the design of a simple adjustable wedge mechanism. Appendix B contains a survey of existing air flow anechoic chambers. Appendix C includes copies of reports of flammability of anechoic wedge materials.
