    摘要: A hybrid airfoil (142) for a gas turbine engine comprises a leading edge portion (148), a trailing edge portion (150) and an intermediate portion (151) between said leading edge portion (148) and said trailing edge portion (150). The leading edge portion (148) is made of a first material, the trailing edge portion (150) is made of a second material, and the intermediate portion (151) is made of a third material. At least two of said first material, said second material and said third material are different materials. A a portion (115) between said leading edge portion and said intermediate portion includes a pocket (127) that receives a non-metallic portion (102A). A connection interface is established between said leading edge portion (148) and said non-metallic portion (102A).
