Abstract
An airfoil cooling system (54) for a gas turbine engine (10) is disclosed. The airfoil cooling system (54) may be formed from at least a first cooling fluid supply system (56), and a second cooling fluid supply system (58). The first cooling fluid supply system (56) may be configured to supply cooling fluids at a first pressure to one or more airfoils of a first row (68) of airfoils, and the second cooling fluid supply system (58) may be configured to supply cooling fluids at a second pressure to the one or more airfoils of the first row (68) of airfoils. Additionally, the second pressure may be lower than the first pressure. As such, each of the one or more airfoils may be cooled by cooling fluids at two different pressures. In particular embodiments, this may allow the airfoils to be cooled, while lowering the cost to the turbine engine (10) for providing such cooling.
