Abstract
A multi-organizational effort led by the Air Force Research Laboratory conducted acoustic emissions measurements on the F-35A and F 35B aircraft at Edwards Air Force Base, California, in September 2013. These measurements followed American National Standards Institute/Acoustical Society of America S12.75-2012 to collect noise data for community noise models and noise exposures to aircraft personnel. In total, over 200 unique locations were measured with over 300 high fidelity microphones. Multiple microphone arrays were deployed in three orientations: circular arcs, linear offsets from the jet-axis centerline, and linear offsets from the jet shear layer. The microphone arrays ranged from distances 10 ft outside the shear layer to 4000 ft from the aircraft with angular positions ranging from 0° (aircraft nose) to 160° (edge of the exhaust flow field). A description of the ground run-up acoustic measurements, data processing, and the resultant data set is provided.
