High-load turbine rotor blade ceramic core weight reduction structure

The utility model relates to a high-load turbine rotor blade ceramic core weight reduction structure, which belongs to the field of aero-engines. The high-load turbine rotor blade comprises a blade body (1), a reinforcing rib (3), a rim plate (4), an extending root (5), and a ceramic core positioning hole (6). The high-load turbine rotor blade ceramic core weight reduction structure is characterized in that the blade body (1) and the extending root (5) are provided with a weight reduction mechanism. The high-load turbine rotor blade ceramic core weight reduction structure is advantageous in that a single-chamber and double-chamber structure is adopted; the structure is simple and easy to be realized, and the weight reduction effect is obvious; in order to meet the demand of high negative heat load, the reinforcing rib having a space angle along the radial direction is disposed at the middle part of the blade, near the air inlet area, which ensures the strength for the blade operation; a unique weight reductio
