Foundry method for fabricating jet engine blade, involves manufacturing shell whose additional part is arranged on another part, where additional part is plane and perpendicular to vertical axis of latter part

摘要

The method involves manufacturing a wax spray having models of part to be fabricated, and manufacturing a shell (302) around the spray. The shell has an additional part (90) that is arranged on a part (32) of the shell while manufacturing the shell. The additional part is plane and perpendicular to a vertical axis (22) of the part (32). The part (32) is formed around a central shaft of the spray. Independent claims are also included for the following: (A) a spray for implementing the foundry method (B) a shell for implementing the foundry method (C) an aircraft engine equipped with a jet engine blade.
