Abstract
A coolable airfoil 10 for rotary machines is disclosed. The airfoil has a passage 54 extending spanwisely through the leading edge region 26 of the blade. The passage has a plurality of trip strips 68 canted toward the direction flow. Each trip strip includes a vortex generator integrally formed with the trip strip which is spaced from the wall of the airfoil. In one embodiment, a plurality of trip strips each having an integral vortex generator are disposed in the passageway and at least one of the vortex generators is of greater height than the remaining vortex generators.
