A testing air turbine of double rotation type for the purpose of researching the dynamical characteristics of turbine blades is described together with the testing method, and the test results obtained from the conventional nozzle blades are also described. The test carried out measuring the torque and thrust acting on the nozz1e diaphragm and the air outlet angles and the velocity coefficients of blade were obtained. The results obtained from the Pitot tube traverses which were performed at same time, coincided with the results by our "torque-thrust method". And the experiments have revealed that the mean velocity and pressure of fluid flow into the turbine blades can be measured directly by the "torque-thrust method" at the running state of turbine.
