<p>PURPOSE: A tip airfoil of a blade for a wind power generator is provided to guarantee an excellent lift-to-drag ratio and lift coefficient, and to rotate the blade with light wind. CONSTITUTION: A tip airfoil(100) of a blade for a wind power generator comprises a suction side(104) and a pressure side(105). The suction and pressure sides are formed at upper and lower sides from a chord which connects a leading edge(101) to a trailing edge(102), respectively. The operating Reynold's number is 30,000~599,000, and an attack angle of the airfoil is 0~21 degrees. The maximum lift coefficient is 1.2~1.5, and the minimum lift coefficient is 0.01~0.06.</p> |
