Claims

[Claims for Utility Model Registration] In an axial flow fluid machine that converts fluid energy into rotation of a rotor, a blade portion having a similar tooth profile is engaged with a tooth profile provided around a rotor disk and extending in the axial direction. The blade assembly is used in place of a non-cooled blade assembly having a turbine blade that is attached to the rotor disk together with a guide device that guides a flow of cooling air into a plenum chamber between the blade part and the rotor disk. A cooled blade assembly comprising: a blade having a wing portion and a root portion that engages the rotor disk within a recess thereof; and a blade having a blade portion having a root portion that engages the rotor disk within a recess thereof; a guide device for guiding the airfoil into an outlet to the power fluid surrounding the wing; a first guide device disposed at the downstream end of the plenum chamber and engageable with the root for sealing the plenum chamber on the downstream side; a separate sealing device having a portion and a second portion disposed in a recess of the rotor disk.
