摘要：
An airfoil for a gas turbine engine is provided that includes a first sidewall and a second sidewall coupled together at a leading edge and a trailing edge, such that a cavity is defined therebetween. A central plenum and an impingement chamber are defined within the cavity. The central plenum channels cooling fluid to the impingement chamber where cooling fluid impinges on the sidewalls. Cooling fluid is discharged from the impingement chamber via film cooling holes.
