METHOD FOR PRODUCTION OF METAL BLADE ELEMENT FOR AVIATION TURBOMACHINE Russian patent published in 2022 - IPC B23P15/02 C23F1/04 B22D25/02 

FIELD: aviation.

SUBSTANCE: invention relates to the production of a metal blade element for an aviation turbomachine, which can be stator or rotor elements. The blade element contains at least one blade with a lower surface and a back located between a front edge and a rear edge of the blade, while the rear edge should have thickness X1. In this case, the method includes a stage of a) manufacture of the blade element by casting by smelted models, wherein the rear edge has thickness X2. The stage b) includes chemical milling of at least the rear edge of one or each blade to obtain the specified thickness X1, which cannot be reached directly at the stage a), wherein thickness X1 is less than thickness X2.

EFFECT: invention allows for obtainment of blade elements with precise sizes and thin rear edges for small blade elements.
