Description
Summary:Two measurement campaigns were conducted as part of a study to quantify the effect of atmospheric turbulence on sonic boom propagation. Supersonic overflights were conducted at the NASA Armstrong Flight Research Center and the Kennedy Space Center to provide different atmospheric conditions for study. Measurements were made of the strength of the turbulence along with the height of the atmospheric boundary layer. Multiple microphone arrays recorded the sonic booms from instrumented aircraft. This work will present statistics detailing the variation of measured booms as a function of the strength of the turbulence and the propagation distance through the atmospheric boundary layer.
