Aft loaded airfoil

摘要

An example airfoil array includes an airfoil array configured to rotate within a turbomachine at a different rotational speed than a fan within the turbomachine. The airfoil array includes a first airfoil (58) that is circumferentially spaced a distance (98) from an adjacent second airfoil (58a). A ratio of the distance (98) to an axial chord length (82) of the first airfoil (58) is less than 1.3. An uncovered turning angle of the first airfoil (58) is greater than 15 degrees.
