摘要：
A method for operating a turbofan engine includes providing a first fan disk configured to rotate in a first rotational direction, coupling a first fan blade to the first fan disk, the first fan blade including a dovetail, an airfoil coupled to the dovetail, and a plurality of channels extending through the dovetail, and channeling airflow through the at least one fan blade such that the airflow is discharged from the airfoil trailing edge to facilitate reducing the operational noise level of the turbofan engine and improve.
