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 non-metallic engine case inlet compression seal for a gas turbine engine to form a compression interface with an airframe bulkhead, comprising:

a non-metallic arcuate interface section;

a non-metallic longitudinal leg section that extends from said non-metallic arcuate interface section, said non-metallic longitudinal leg section configured to be at least partially radially supported on an outer case structure of said gas turbine engine, said non-metallic longitudinal leg section comprises a stepped surface adjacent to a forward circumferential edge of said outer case structure;

a non-metallic mount flange section that extends transversely from said longitudinal leg section, said non-metallic mount flange having a multitude of apertures to mount said non-metallic engine case inlet compression seal to said outer case structure of said gas turbine engine; and

a fiber reinforcement bonded to an outer surface of at least one of said non-metallic arcuate interface section, said non-metallic longitudinal leg section, and said non-metallic mount flange section.

2. The non-metallic engine case inlet compression seal as recited in claim 1 , wherein said fiber reinforcement includes an aramid material.

3. The non-metallic engine case inlet compression seal as recited in claim 1 , wherein said non-metallic arcuate interface section has a durometer hardness different than a durometer hardness of said non-metallic longitudinal leg section.

4. The non-metallic engine case inlet compression seal as recited in claim 1 , wherein said non-metallic longitudinal leg section is circular.
