Abstract
A rotor for high temperature and high speed applications including a rotatable hub, a plurality of rotor blades mounted on the hub for rotation therewith, and a shroud coupled to the rotor for rotation therewith and lying radially outwardly of at least a portion of the blades so that, upon rotation of the rotor, the shroud is unevenly deformed due to the centrifugal force resulting from the mass of the blades. This uneven deformation of the shroud places it in shear. The shroud is stronger in hoop tension than in shear. Centrifugal members are positioned between adjacent blades to apply a centrifugal force to the shroud between the blades. This causes the shroud to be more evenly deformed to reduce the shear.
