TURBINE COMPONENT SURFACE COOLING SYSTEM WITH PASSIVE FLOW MODULATION

摘要

A system (20) according to various embodiments includes: a cooling network (210) within a turbine component (2), the cooling network (210) including at least one passageway (220) fluidly connected with a surface of the turbine component (2); a cooling fluid source (230) for providing a cooling fluid to the cooling network (210); and a temperature-actuated flow modulating device (240) fluidly connected with the cooling fluid source (230) and the cooling network (210), the temperature-actuated flow modulating device (240) configured to: detect an ambient air (250) temperature proximate the turbine component (2); and control a flow of the cooling fluid to the cooling network (210) based upon the detected ambient air (250) temperature.
