Cooling arrangement for a turbine engine component

摘要

An example turbine component cooling arrangement includes a film plate (86) having a plurality of film channels (82) extending from film channel entrances (98) on a first side of the film plate (86) to corresponding film channel exits (94) on an opposing second side of the film plate (86). The arrangement also includes an impingement plate establishing a plurality of impingement channels. The impingement plate (78) is spaced a distance from the film plate (86). The plurality of impingement channels (74) are configured to direct a fluid across the distance to contact the film plate (86) between adjacent ones of the film channel entrances (98). In one example, the distance from the film plate (86) to the impingement plate (78) is between two and four times more than diameter of one of the impingement channels (74).
