The invention belongs to the technical field of turbine engines, and discloses a fluid velocity pulsation generator which comprises a casing (1), a flange (2), a baffle (3), a rotating shaft sleeve (4), a rotating shaft (5), a bearing (6) and a flower wheel (8). The outer side of the casing (1) is fixedly connected with the flange (2); a baffle (3) is fixed on the inner wall of the casing; the side wall of the casing is provided with a through hole through which the rotating shaft sleeve (4) penetrates and is fixed with the casing; the rotating shaft (5) penetrates through the bearing sleeves (4), and the two ends of the rotating shaft (5) are supported in the bearing sleeves (4) through bearings (6); and the pattern wheel (8) is fixed on the rotating shaft (5). The flow area is periodically changed due to relative rotation between the pattern passing wheel and the baffle, so that pulsation of air flow is generated; the excitation frequency can be changed by adjusting the rotating speed of the motor; by chang
