<p>A family of airfoils for use in a high solidity factor blade (100) having a leading edge portion (115) and a trailing edge portion (125), a tip portion, and a root portion, has a plurality of airfoil sections (20, 30,40,60,75). Each section has : one of any of a plurality of camber lines extending from the leading edge portion (115) to the trailing edge portion (125), the camber lines being scalable relative to each other, each having the same relative shape, the camber lines having a minimal slope from the leading edge to about a 40% chord and an apogee at about a 74% chord; a scalable thickness ratio of between about 2% to about 7.5%; and, a maximum thickness position which is located from about a 37.5% chord for an airfoil at the tip portion of the blade (100) to about a 35.0% chord for an airfoil at the root portion of the blade (100).</p> |
