| Abstract: | This paper presents a test method of force measurementto measure different pitching moment at the same condition by changingdistance between model and reference point of moment of balance.Thenby means of mathematical processing or drawing,accurate centre of pr-essure was obtained at small angle of attack.The present method was used for certain model of wind tunnel andthe results were satisfactory. |
