Waseda University, International Conference Center), Tokyo Japan, Nonlinear effect, as well as geometrically decreasing effects, in jet noise is examined by Burgers equation. A captive firing test conducted in JAXA is used. The resulting facts are that (1) propagation mode changes from cylindrical type to spherical one as the longitudinal coverage becomes longer due tu reflection from the ground and so on, (2) nonlinearity distributes acoustic energy around peak frequency to waves with higher frequency. Especially, what is important for the purpose of rocket launch is that, the increase of sound pressure level in higher frequency region resulting from the energy distribution stated above is in 130-2000 Hz, and the maximum value is likely to be about 6dB., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065207044, レポート番号: JAXA-SP-11-015},
