Paper Abstract

The paper presents the results of experimental studies of the acoustic field generated by a supersonic flooded jet on the wind tunnel of the Vertical Jet Unit (VJU) ITAM SB RAS. The submerged jet came out vertically upward into a large enough room. Measurements are made by 9 microphones, which are placed on a ring with a radius of 265 mm, which moved vertically. The microphone inputs are installed at a radius of 235 mm (through 36°) symmetrically with respect to the axis of the jet. The time spectra of the acoustic field and the shape of the phase front at npr = 5 at heights from -50 to 495 mm are considered. The Mach number in the output section was equal to unity.
