Turbine airfoil suction aided film cooling means |
摘要 |
Film cooling effectiveness for internally air cooled turbine blades of gas turbine engines is enhanced by including an interconnecting passage to the film cooling hole that is in communication with a lower internal pressure in the blade to create a suction at the exit end of the film hole to limit penetration into the gas stream.
