FIELD: engines and pumps.
SUBSTANCE: invention relates to the jet engine shielding elements. Shielding element (30) is located on above of the gaps between the turbine rotor adjacent blades (10) flange (20) sections and is made of a composite material with a ceramic matrix with possibility of the gap between the flange (20) sections shielding due to coming into contact along the flange sections bodies internal surfaces. From the airfoil input edge the shielding element section is made elongated and includes a second shielding surface located between the turbine rotor adjacent blades tail portions. Each of the flange sections includes a rear skirt, made on the flange section corresponding body output edge side. First contact areas are configured to come into contact with the turbine rotor adjacent blades tail sections side surfaces and with the rear skirts holding sections. Second contact areas are configured to come into contact with the turbine rotor adjacent blades tail sections side surfaces.
EFFECT: technical result is the shielding of gaps between the turbine rotor adjacent blades flange sections.
