FIELD: mechanical engineering; gas turbines.
SUBSTANCE: proposed device for fastening blades of gas turbine first stage has plates with U-shaped projection arranged between two adjacent blades for engagement with corresponding U-shaped groove and pair of ends bent through 90o relative to axis of plate for locking blade axially relative to disk. Blade fastening device of gas turbine second stage has plates arranged between end part of blade base and turbine disk. Each said plate is provided with ends for axially holding the blade. Rotor disk on section of second stage is provided with cavities for fitting blades of second stage.
EFFECT: provision of non-expensive device consisting of smaller number of parts for fastening gas turbine blades.
