Abstract
A cooling circuit according to an embodiment includes: a cooling circuit for a multi-wall blade, the cooling circuit including: a pressure side cavity with a surface adjacent a pressure side of the multi-wall blade; a suction side cavity with a surface adjacent a suction side of the multi-wall blade; a central cavity disposed between the pressure side and suction side cavities, the central cavity including no surfaces adjacent the pressure and suction sides of the multi-wall blade; a first leading edge cavity with surfaces adjacent the pressure and suction sides of the multi-wall blade; and at least one impingement opening for fluidly coupling the leading edge cavity with a second leading edge cavity.

A cooling circuit for a multi-wall blade, comprising:
- a pressure side cavity with a surface adjacent a pressure side of the multi-wall blade;
- a suction side cavity with a surface adjacent a suction side of the multi-wall blade;
- a first leading edge cavity with surfaces adjacent the pressure and suction sides of the multi-wall blade, the first leading edge cavity located forward of the pressure and suction side cavities;
- a second leading edge cavity with surfaces adjacent the pressure and suction sides of the multi-wall blade, the second leading edge cavity located forward of the first leading edge cavity;
- at least one leading edge film hole for fluidly coupling the second leading edge cavity to a leading edge of the multi-wall blade;
- at least one channel for fluidly coupling the second leading edge cavity to a tip of the multi-wall blade;
- a turn for directing a first portion of a flow of cooling air from the pressure side cavity into the first leading edge cavity;
- a turn for directing a second portion of the flow of cooling air from the suction side cavity into the first leading edge cavity, the first and second portions of the flow of cooling air recombining into a recombined flow of cooling air in the first leading edge cavity;
- and
- a turn for directing the recombined flow of cooling air from the first leading edge cavity into the second leading edge cavity.
