The Interdisciplinary Consulting Corporation (IC2) proposes to develop a field-deployable wireless data acquisition system (WDAS) for microphone phased arrays that are applicable in noise-source localization or beamforming measurements such as those encountered during airframe noise flyover measurement tests. This proposed technology is in response to NASA SBIR 2019 Phase I solicitation subtopic A1.02 Quiet Performance - Airframe Noise Reduction for the improvement of ldquo;innovative source identification techniques for airframe noise sources, such as landing gear and high lift systems.rdquo;The proposed measurement system expands NASArsquo;s technology portfolio to allow for faster, higher-accuracy, lower-effort/cost testing by minimizing the technological, logistical, and cost-prohibitive issues of performing field-deployed microphone phased-array tests. These improvements will allow for increased usage of phased-array flyover testing, and increased size/resolution arrays. Potential applications for the system include field-deployed noise flyover-measurement tests, and field-deployed engine-stand noise emissions tests.The realization of this capability not only benefits the testing of next-generation innovative noise-reduction airframe structures, but also impacts turbine and fairing test facilities, extending the current capabilities of NASArsquo;s flight- and ground-test facilities.
