A coolable rotor blade for an axial flow rotary machine which comprises: a spar which extends spanwisely, which has a projection and which has a root section and an airfoil section; a shell for defining the airfoil surface of the rotor blade which extends telescopically over and against a portion of the projection on the spar, which is spaced from the airfoil section of the spar and which is joined to the airfoil section of the spar for defining cooling passages therebetween and for transmitting radial loads acting on the shell to the airfoil section of the spar during operation of the rotor assembly; a platform which extends over the projection on the spar and over and against the portion of the shell extending over the projection on the spar to trap the shell between the platform and the projection on the spar.
