The invention provides a high-speed wind tunnel gust generating device based on a trailing edge blowing form. The high-speed wind tunnel gust generating device comprises a wing-shaped left side wall plate, a wing-shaped right side wall plate, an upper end plate, a lower end plate, an adjusting switch, a coupling, a driving motor and a gas supply pipeline, and the wing-shaped left side wall plate, the wing-shaped right side wall plate, the upper end plate and the lower end plate are respectively connected together to form a wing-shaped shell; a pressure stabilizing cavity and an adjusting cavity are formed in the wing-shaped shell in the chordwise direction and communicate with each other, a jet flow hole channel is formed in the tail edge of the wing-shaped shell and connected with the adjusting cavity, and vertical gust is generated through tangential blowing of the jet flow hole channel; and an adjusting switch is installed in the adjusting cavity, and the flow of the jet flow hole channel can be adjusted by controlling the rotation degree of the adjusting switch. The device can be conveniently connected with a wind tunnel without inertial load; and the control form is simple, and gust fields with a wide frequency range and various forms can be generated so as to realize reasonable simulation of gust disturbance in the atmosphere.
