Abstract
A turbine flowpath structure includes a first generally U-shaped flowpath channel having a first leg having a first inwardly facing side shaped as a turbine blade suction-side airfoil surface, a second leg having a second inwardly facing side shaped as a turbine blade pressure-side airfoil surface, and a web connecting the first leg and the second leg, wherein the web has an inwardly facing inner flowpath surface. There is typically provided a spar that engages at least one of the first leg and the second leg. In one application, there is a plurality of the generally U-shaped flowpath channels arranged around the periphery of a turbine disk, and a plurality of spars positioned between each pair of adjacent generally U-shaped flowpath channels to anchor them to the turbine disk.
