GAS TURBINE ENGINE COMPONENT ARRANGEMENT

摘要

A gas turbine engine component is provided that can be cooled with a cooling media such as air using a variety of passages. In one form, cooling fluid is routed through a hole that exits at least partially through a pedestal formed between walls. A plurality of cooling holes can be provided through a trench face and in some forms can include a diffusion through a divergence in the hole exit. J-Hook passages can be provided through a trench face, and, in some forms, multiple trenches can be provided. A cooling hole having a neck portion can be provided, as can a cooling hole with one or more turns to reduce a total pressure. In one form, a corrugated cooling passage can be provided.

主权项

1. An apparatus comprising
a multi-wall gas turbine engine component having an internal passage disposed between a first wall and a second wall and structured to flow a cooling fluid through the internal passage to cool the multi-wall gas turbine engine component, a support connecting the first wall with the second wall, the cooling fluid routed along a side of the support during operation of the component, and a hole oriented to pass through a portion of the support and configured to flow the cooling fluid, the hole in fluid communication with the internal passage.
