The invention discloses an integrated ducted fan test bench, and relates to the technical field of test benches, a driving element and a tilting module are both installed on a lower bench body, an output shaft of the driving element is connected with an input shaft of a speed change element, and an output shaft of the speed change element is connected with a rotor system through a rotating main shaft. A torque rotating speed measuring instrument is installed on the periphery of the rotating main shaft, a connecting frame is installed at the upper end of the tilting module, the middle weighing element and the peripheral weighing element are both installed on the connecting frame, a first upper cover plate is installed at the upper end of the peripheral weighing element, the duct body is installed on the first upper cover plate, the peripheral weighing element is arranged around the periphery of the middle weighing element, and a second upper cover plate is installed at the lower end of the duct body. And the upper end of the middle weighing element penetrates through the first upper cover plate and is connected with the rotor wing system. Various aerodynamic force data of the duct body and the rotor wing system can be measured independently at the same time, the integration degree is high, the test cost is greatly reduced, and the test efficiency is improved.
