摘要： An airfoil (10) comprises an airfoil body (12) with an internal cavity (16) and inner and outer covers (32,34). The airfoil body defines a first major surface of the airfoil, and a rib (18) extends along the internal cavity. The inner cover (32) is bonded to the airfoil body (12) over the internal cavity (16), and includes a coupling element (20) extending along the internal cavity in cooperative engagement with the rib. The outer cover (34) is bonded to the airfoil body (12) over the inner cover (32), and defines a second major surface of the airfoil.

摘要： A rotor blade (26) is provided for a turbine engine. This rotor blade (26) includes an airfoil (30) extending longitudinally between a leading edge (42) and a trailing edge (44). The airfoil (30) extends spanwise to a tip (28). The airfoil (30) is configured with a plurality of projections (74) arranged longitudinally along the tip (28).
