The invention discloses a wind tunnel test platform for helicopter maneuvering flight state simulation, which comprises a connecting part, a lifting mechanism, an advancing and retreating mechanism, a rolling mechanism, a pitching mechanism and a yawing mechanism, and is characterized in that the connecting part is used for connecting a to-be-tested rotor mechanism; the yawing mechanism comprises a front yawing piece and a rear yawing piece, the front yawing piece is in shaft hinge with the rear yawing piece through a first shaft, the rear yawing piece is in shaft hinge with the lifting mechanism or the advancing and retreating mechanism through a second shaft, the second shaft and the first shaft are both parallel to the Z axis, and the front yawing mechanism is connected with the connecting part through a rolling mechanism and/or a pitching mechanism; the front yawing piece is provided with a first power assembly used for enabling the front yawing piece to rotate with the first shaft as the axis, and the rear yawing piece is provided with a second power assembly used for enabling the rear yawing piece to rotate with the second shaft as the axis. Multi-degree-of-freedom motion simulation can be carried out, and when yaw motion simulation is carried out, the technical problems that an existing test platform is poor in continuity and the orientation of a to-be-tested rotor mechanism cannot be changed in real time can be solved.
