BLADE EQUIPPED WITH SHELVES, HAVING SUPPORTING LEG Russian patent published in 2019 - IPC B29B11/16 

FIELD: machine building.

SUBSTANCE: invention relates to a workpiece for a gas turbine engine blade, as well as to a single-piece blade, which can be made using such a workpiece, to a blade wheel and to a gas turbine engine containing such a blade. Proposed blank of gas turbine engine comprises first lengthwise section (31), second lengthwise section (32), third lengthwise section (33) and first crosswise section (34). First longitudinal section (31) is configured to form at least a portion of the shank of the blade. Second longitudinal section (32) continues upward the first longitudinal section and is configured to form at least part of leg. Third longitudinal section (33) continues upwards the second longitudinal section and is made with possibility to form the feather part. First cross-section (34) extends transversely from the connection between the second and third longitudinal sections and is configured to form a first flange. First inclined section (36) passes from the connection between the first and the second longitudinal sections to the first cross-section and is made with possibility to form a supporting strut for the first shelf.

EFFECT: invention makes it possible to increase flange rigidity and to reduce its deformation during operation.
