Abstract
This paper shows the wind tunnel study of pressure distribution on a rotor blade of horizontal axis wind turbine. Comparison of the pressure distribution of rotational and static situation for the tip and root regions of the blade. The pressure distribution at tip region coincides for rotational and static situation. The pressure distribution at root region shows much difference for rotational and static situation. Especially for low tip speed, the normal force coefficient at root region shows larger value than those for the static situation.
