The invention discloses a high-flow and high-frequency pulse air blowing device. The device comprises a front-end plenum chamber; one end of the front-end plenum chamber is an air inlet end, and the opposite other end is an adapter end; the device further comprises a rotating shaft which is provided with an inner cavity with one end communicating with the adapter end, and multiple sets of air guide holes communicating with the inner cavity are formed in the side wall of the rotating shaft; the device further comprises a shell which is arranged outside the rotating shaft; a group of air blowingholes are formed in the shell, and the positions of the air blowing holes match those of the air guide holes; the device further comprises a motor which is connected with the rotating shaft and drives the rotating shaft to rotate. The high-flow and high-frequency pulse air blowing device can be used for high-flow and high-frequency pulse air blowing, and can be suitable for a large-size model pulse air blowing flow control test.
