A model-scale airframe noise test of a high-speed civil transport (HSCT) was conducted in the Boeing Low-speed Aeroacoustic Facility. The test had the following objectives: provide an estimate of HSCT airframe noise levels; identify the major HSCT airframe noise sources; and assess the accuracy of the current HSCT airframe noise predictions. The noise levels were estimated by projecting data from free-field microphones to full-scale conditions. The result was an approach level of 91 EPNdB, well… CONTINUE READING
