抄録
Devices for reducing jet noise were tested and evaluated from the aerodynamic and aeroacoustic points of view. Investigated suppressors were slotted tubes and perforated tubes. Slotted tubes were varied in the number and the length of slot. As for the perforated tube, the effect of perforation angle that is the angle between the perforation axis and the tube axis were investigated as well as the effect of porosity. The length, the exit diameter and the thickness were fixed to 50, 10 and 2mm respectively in the present report. Sound pressure level and thrust of devices for reducing noise were measured and compared with each other. Slotted tubes showed rather preferable performance with respect to thrust while perforated tube exerted better noise reducing effect.
