Abstract

Interaction between a sonic boom and cascaded blades is studied numerically. The incident sonic boom is modeled by a finite amplitude N wave with a short rising time, and the time dependent transonic cascade flow with a passage shock inside is solved. Detailed mechanism on reflection and transmission of a sonic boom by the cascade and unsteady aerodynamic force exerted on blades are elucidated. The peak amplitude of the unsteady blade force is the same order of magnitude as the pressure amplitude of the incident sonic boom.
