摘要: A rotor blade includes an airfoil, integral platform, and a dovetail integrally joined to the platform. The neck extending between pair of lobes configured engage complementary slot in disk. undercut outer face for introducing stress concentration thereat. relieves at expense increasing high cycle fatigue life blade.
