Acoustic Array Installation

D&D Mechanical’s Role

D&D Mechanical, Inc. was selected by Jacobs ROME Group and NASA LaRC to provide the structural, electrical and mechanical scopes of work required to integrate the new acoustic sensor array and associated traverse mechanism into the existing wind tunnel. The project required the construction and installation of a modular building addition and substantial structural reinforcement of the existing structure. Additionally due to the extreme accuracy required for repeatability of positioning of the acoustic array and the associated traverse assembly precision alignment utilizing tracking lasers was required to maintain tolerances across the 22 foot wide traverse throughout a 70 linear foot rail system designed to support the traverse and acoustic array in the wind tunnel test cell. Due to the nature of the equipment interface into the existing building it was desired to maintain all associated work under one contract to ensure minimal impact to the project schedule due to coordination.
