Abstract

An airfoil (120) for use with a gas turbine engine (20) includes a pressure side wall (402) and a suction side wall (404). The suction side wall (404) is configured to be exposed to less pressure than the pressure side wall (402) during operation of the gas turbine engine (20). The blade (120) also includes a plurality of ribs (425) forming a plurality of trapezoidal shaped cavities to receive a cooling airflow. The plurality of ribs (425) being shaped in a way to allow for thermal growth of the airfoil, while minimizing stress in the airfoil (120).
