Abstract (en)

A turbine blade assembly includes a first and a second blade root of a first and a second turbine blade inserted adjoining to each other, into a rim section of a rotor disc thereby defining a common cavity between a first and a second non-aerofoil sections of the turbine blades. A sealing element is located inside the common cavity, adhered to an inner surface of the common cavity. The sealing element extends between the first and the second non-aerofoil sections to at least partially fill the common cavity. The sealing element includes an adhesive material, or is formed solely from the adhesive material. The sealing element seals the gap between the non-aerofoil sections and consequently protects the non-aerofoil sections, particularly the shanks of the turbine blades and the rim section of the rotor disc, from the harmful effects of the hot working gases.
