Ordinary, we research the characteristics of turbine blades with cascade tunnel, but we cannot expect from those researches the characteristics of turbine blades at moving state. Then, it is necessary to carry actual turbine testings to know the dynamical characteristics of turbine blades. We are researching the dynamical characteristics of various turbine blades with two testing turbines ; the one is the impulse turbine of partial admission and the other is the specially designed low pressure turbine of double motion type. In this paper, we report the results which have been obtained by the former. We measured the torque and thrust of turbine shaft, and calculated the amount and direction of exit velocity from blades. On the other hand, we measured the outlet flow angle and velocity by yaw meter and pitot tube. Then, compared these two methods and found that the first method is more simple than the second and there is good agreement between the both results.
