It is necessary to carry out actual turbine testings to know the characteristics of turbine blades in the moving state. Then, we research the dynamical characteristics of turbine blades with two testing turbines ; one is an impulse turbine of partial admission and the other is a specially designed low pressure turbine of double rotation type. In this paper, we report the results which have been obtained with the former. We measured the torque and thrust of turbine shaft, and calculated the magnitude and direction of exit velocity from blades. On the other hand, we measured the outlet flow angle and velocity by yawmeter and pitot tube. Comparing these two methods we found that the first method was more simple than the second and there was a good agreement between both results.
