Miyazaki Citizen's Plaza), Miyazaki, Japan, The study involved investigating the aerodynamic performance of several wings with different leading edge angles to validate the usefulness of a forward-swept wing in significantly reducing sonic boom at supersonic cruise. A total of 13 wing-body-engine nacelle configurations for supersonic business jet model were defined with varying wing planforms; the associated aerodynamic drag was evaluated using the three-dimensional compressive Euler equation, and the augmented Burgers equation was used to evaluate the acoustic level of the sonic boom. The calculated results for supersonic cruise conditions indicated that the maximum acoustic level of the sonic boom of a forward-swept wing was approximately 4.8 PLdB lower than that of the original backward-swept wing. Furthermore, a forward-swept wing reduced the aerodynamic drag as effectively as a backward-swept wing in supersonic cruise. The sonic boom signature on the ground level indicated that forward-sweeping of the wing led to multi-peaks signature on the bottom peak of the trailing sonic boom, and thus, the forward-swept wing could reduce the intensity of trailing sonic boom., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1830029020, レポート番号: JAXA-SP-18-005},
