Abstract

The present disclosure provides methods and systems for an airfoil of a gas turbine engine. An airfoil of a gas turbine engine may comprise an airfoil body having a body contact surface, and an airfoil edge coupled to the body contact surface, wherein at least one of the airfoil body or airfoil edge comprises a fiber metal laminate.

Claims (25)

1. An airfoil in a gas turbine engine, comprising:

a pressure side half of the airfoil comprising a fiber metal laminate, wherein the pressure side half comprises:

a middle pressure side layer comprising a middle pressure side ply length and a middle pressure side plurality of plies;

an outer pressure side layer coupled to the middle pressure side layer, wherein the outer pressure side layer comprises an outer pressure side ply length and an outer pressure side plurality of plies; and

an inner pressure side layer coupled to the middle pressure side layer, the inner pressure side layer comprising an inner pressure side ply length and an inner pressure side plurality of plies,

wherein the outer pressure side ply length is larger than the middle pressure side ply length, and the middle pressure side ply length is larger than the inner pressure side ply length, wherein the outer pressure side plurality of plies comprises fewer plies than the middle pressure side plurality of plies, and wherein the middle pressure side plurality of plies comprises fewer plies than the inner pressure side plurality of plies; and

a suction side half of the airfoil comprising the fiber metal laminate, wherein the suction side half comprises:

a middle suction side layer comprising a middle suction side ply length and a middle suction side plurality of plies;

an outer suction side layer coupled to the middle suction side layer, wherein the outer suction side layer comprises an outer suction side ply length and an outer suction side plurality of plies; and

an inner suction side layer coupled to the middle suction side layer, the inner suction side layer comprising an inner suction side ply length and an inner suction side plurality of plies,

wherein the outer suction side ply length is larger than the middle suction side ply length, and the middle suction side ply length is larger than the inner suction side ply length, wherein the outer suction side plurality of plies comprises fewer plies than the middle suction side plurality of plies, and wherein the middle suction side plurality of plies comprises fewer plies than the inner suction side plurality of plies, and

wherein the pressure side half is coupled to the suction side half.

2. An airfoil in a gas turbine engine, comprising:

a pressure side half of the airfoil comprising a fiber metal laminate, wherein the pressure side half comprises:

a middle pressure side layer comprising a middle pressure side ply length and a middle pressure side plurality of plies;

an outer pressure side layer coupled to the middle pressure side layer, wherein the outer pressure side layer comprises an outer pressure side ply length and an outer pressure side plurality of plies; and

an inner pressure side layer coupled to the middle pressure side layer, the inner pressure side layer comprising an inner pressure side ply length and an inner pressure side plurality of plies,

wherein the outer pressure side ply length is shorter than the middle pressure side ply length, and the middle pressure side ply length is shorter than the inner pressure side ply length, wherein the outer pressure side plurality of plies comprises more plies than the middle pressure side plurality of plies, and wherein the middle pressure side plurality of plies comprises more plies than the inner pressure side plurality of plies; and

a suction side half of the airfoil comprising the fiber metal laminate, wherein the suction side half comprises:

a middle suction side layer comprising a middle suction side ply length and a middle suction side plurality of plies;

an outer suction side layer coupled to the middle suction side layer, wherein the outer suction side layer comprises an outer suction side ply length and an outer suction side plurality of plies; and

an inner suction side layer coupled to the middle suction side layer, the inner suction side layer comprising an inner suction side ply length and an inner suction side plurality of plies,

wherein the outer suction side ply length is shorter than the middle suction side ply length, and the middle suction side ply length is shorter than the inner suction side ply length,

wherein the outer suction side plurality of plies comprises more plies than the middle suction side plurality of plies, and wherein the middle suction side plurality of plies comprises more plies than the inner suction side plurality of plies, and

wherein the pressure side half is coupled to the suction side half.
