However, the shroud also imposes penalties in the form of a mass at the tip of the blade, which requires body loads due to the centrifugal force field to be carried by the rest of the airfoil.
Dynamic stresses, thus, must be adequately taken into consider- ation in the design of vanes and struts, but the absence of centrifugal force poses less strin- gent requirements than for rotating blades.
This observa- tion is consistent with the blade experiencing increased stiffness as a direct consequence of the higher centrifugal force, as the rotor speed increases.
where {Po}, {T}, and {F()} are stationary gas pressure, thermal condition, and centrifugal forces.
