The invention discloses a helicopter tail rotor simulation system for a wind tunnel test. The system comprises a base, a driving mechanism, a supporting arm, a tilting adjustment mechanism and a tailrotor transmission measurement control module, wherein one end of the supporting arm is a fixed end, the other end is a tilting end, the fixed end of the supporting arm is rotatably connected with thebase, the driving mechanism is used for driving the supporting arm to rotate around the base, the tilting adjusting mechanism is installed at the tilting end of the supporting arm and can move in theaxial direction of the supporting arm and rotate around the axial direction of the supporting arm, and the tail rotor transmission measurement control module is rotatably connected with the tilting adjustment mechanism. Flight states of different helicopters at different inclination angles can be simulated.
