冷却スロット保護装置および保護シールド、ならびに構成部品を覆う方法

Document Type and Number:

Japanese Patent JP4283270

Kind Code:

B2

Abstract:

A gas turbine engine is used for power generation or propulsion and includes vanes (26). Each vane (26) includes a trailing edge (30) having a curvature and cooling slots (32) that cool the vane. A photochemical edge shield (34) includes an edge (36) and projections (38) that project from the edge (36). Before coating the vane, the photochemical edge shield (34) is positioned on the vane (26) such that each of the projections (38) is received in one of the cooling slots (32). A ceramic coating is then applied to the vane. The photochemical edge shield (34) prevents the ceramic coating from entering and clogging the cooling slots (32) of the vane (26) during the ceramic coating process.
