Title:
IMPINGEMENT HOLES FOR TURBINE ENGINE COMPONENT
Document Type and Number:
Japanese Patent JP2017141829
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide impingement holes for a turbine engine component.SOLUTION: An apparatus for an impingement hole for an engine component of a gas turbine engine includes an impingement baffle. The impingement baffle is separated from an impingement surface and includes a plurality of impingement holes for providing an impingement flow to the impingement surface. The impingement holes can have an angled upstream edge such that an inlet has a greater cross-sectional area than an outlet. Walls of the impingement holes can have a hood to provide a higher shear flow content to minimize dust accumulation on the impingement surface.SELECTED DRAWING: Figure 1
