Abstract
A trailing edge cooling system for a multi-wall blade, including: a set of outward legs extending toward a trailing edge of the multi-wall blade and fluidly coupled to a coolant feed; a set of return legs extending away from the trailing edge of the multi-wall blade and fluidly coupled to a coolant collection passage; and a connecting system for fluidly coupling the set of outward legs and the set of return legs; wherein the set of outward legs is radially offset from the set of return legs along a radial axis of the multi-wall blade.

A trailing edge cooling system for a multi-wall blade, comprising:
- a set of outward legs extending toward a trailing edge of the multi-wall blade and fluidly coupled to a coolant feed;
- a set of return legs extending away from the trailing edge of the multi-wall blade and fluidly coupled to a coolant collection passage;
- and
- a connecting system for fluidly coupling the set of outward legs and the set of return legs;
- wherein the set of outward legs is radially offset from the set of return legs along a radial axis of the multi-wall blade.
A multi-wall turbine blade, comprising:
- a trailing edge cooling system disposed within the multi-wall turbine blade, the trailing edge cooling system comprising:
- a set of outward legs extending toward a trailing edge of the multi-wall blade and fluidly coupled to a coolant feed;
- a set of return legs extending away from the trailing edge of the multi-wall blade and fluidly coupled to a coolant collection passage;
- and
- a connecting system for fluidly coupling the set of outward legs and the set of return legs;
- wherein the set of outward legs is radially offset from the set of return legs along a radial axis of the multi-wall blade.
A turbomachine, comprising:
- a gas turbine system including a compressor component, a combustor component, and a turbine component, the turbine component including a plurality of turbine blades, at least one of the turbine blades including a multi-wall blade;
- and
- a trailing edge cooling system disposed within the multi-wall blade, the trailing edge cooling system including:
- a set of outward legs extending toward a trailing edge of the multi-wall blade and fluidly coupled to a coolant feed;
- a set of return legs extending away from the trailing edge of the multi-wall blade and fluidly coupled to a coolant collection passage;
- and
- a connecting system for fluidly coupling the set of outward legs and the set of return legs;
- wherein the set of outward legs is radially and circumferentially offset from the set of return legs along a radial axis of the multi-wall blade.
