In this paper, two kinds of horizontal axis wind turbines, namely, upwind and downwind, were investigated and compared. In this experiment, the strain distribution and the rate of strain fluctuation on the surface of the rotating blade, and the strain and bending moment on the blade root, etc. were measured. As a result, the difference between upwind and downwind types was solved. The result is very important for the design of a horizontal axis wind turbine.
