PURPOSE: A inversion dynamometer for the underwater moving object tank experiment is provided to reduce the mechanical noise by not using the gear, and to offer the inversion dynamometer for the tank experiment in which the structure is simple. CONSTITUTION: The inversion dynamometer for the underwater moving object tank experiment includes: an internal flange type propelling shaft(6); an electric motor(1); a first hollow type 2-axis force sensor(5); a flange type hollow propelling shaft(12); a hollow type electric motor(7); and a second hollow type 2-axis force sensor(11). The internal flange type propeller shaft is connected to the rear part propeller. The electric motor runs the inward flange type propeller shaft. The first hollow type the biaxial force sensor is arranged between the electric motor and internal flange type propeller shaft and measures thrust and torque of the internal flange type propeller shaft generated by the rotation of the propeller at the same time. The flange type hollow propeller shaft is all connected above statement to propeller. The hollow electric motor runs the flange type hollow propeller shaft. The second hollow biaxial force sensor is arranged between the flange type hollow propeller shaft and hollow electric motor and measures thrust and torque of the flange type hollow propeller shaft which all generated by the rotation of propeller at the same time. The internal flange type propeller shaft passes through the hollow electric motor, and the second hollow biaxial force sensor and flange type hollow propeller shaft and the electric motor and hollow electric motor(7) are serially arranged.
