Abstract

A non-metallic engine case inlet compression seal for a gas turbine engine includes a non-metallic longitudinal leg section that extends from the non-metallic arcuate interface section and a non-metallic mount flange section that extends from the longitudinal leg section.

Claims (8)

1. A gas turbine engine, comprising:

an outer case structure defined along an engine axis;

a non-metallic mount flange section having a multitude of apertures to mount said non-metallic mount flange section to said outer case structure forward of a fan section of said gas turbine engine;

a non-metallic longitudinal leg section that extends transversely from said non-metallic mount flange section, said non-metallic longitudinal leg section at least partially radially supported on said outer case structure; and

a non-metallic arcuate interface section that extends from said non-metallic longitudinal leg section, said non-metallic arcuate interface section defined around said engine axis, wherein said non-metallic arcuate interface section has a durometer hardness different than a durometer hardness of said non-metallic longitudinal leg section.

2. The gas turbine engine as recited in claim 1 , wherein said non-metallic longitudinal leg section is generally parallel to said engine axis.

3. The gas turbine engine as recited in claim 1 , wherein said non-metallic longitudinal leg section comprises a stepped surface that abuts a forward edge of said outer case structure.

4. The gas turbine engine as recited in claim 1 , wherein said outer case structure that forms said forward edge of said outer case structure is stepped.
