• This paper describes a study on the development of a proper airfoil section for the vertical axis wind turbine (VAWT). We aim to abtain pitching moment in the negative direction without losing the excellent characteristics of a symmetrical-type airfoil section. Thus, we propose an increase of the thickness of the symmetrical-type airfoil by giving a meanline reversal, that is, negative meanline near leading edge and positive one near trailing edge, measured from blade chord line. Thus, the airfoil section can be designed by setting the parameters of a reverse meanline and basic airfoil section, and this airfoil section will be called the TW series airfoil section. From the three component force characteristics measured in wind tunnel experiment, TW series airfoil section is regarded to preferable for VAWT, thus, validity of design concept of TW series airfoil section using reverse meanline was demonstrated.
