GAS TURBINE ENGINE WITH CARBON/CARBON COMPOSITE PISTON SEAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17994188 titled 'GAS TURBINE ENGINE WITH CARBON/CARBON COMPOSITE PISTON SEAL

Simplified Explanation

The abstract describes a gas turbine engine with a seal made of a composite material containing carbon fibers in a carbon matrix.

• The rotor of the gas turbine engine has a seal surface.
• The shaft has an annular seal channel that opens to the seal surface.
• A seal made of a composite material is disposed in the annular seal channel to seal against the seal surface.
• The composite material of the seal includes carbon fibers in a carbon matrix.

Potential Applications

The technology described in this patent application could be applied in various gas turbine engines used in aerospace, power generation, and other industrial applications.

Problems Solved

This innovation helps improve the efficiency and performance of gas turbine engines by providing a durable and effective sealing solution that can withstand high temperatures and pressures.

Benefits

The composite seal material offers enhanced wear resistance, reduced maintenance requirements, and increased longevity compared to traditional seal materials.

Potential Commercial Applications

One potential commercial application of this technology could be in the manufacturing and maintenance of gas turbine engines for aircraft, power plants, and other industrial machinery.

Possible Prior Art

One possible prior art could be the use of traditional seal materials such as rubber or metal in gas turbine engines. However, the use of a composite material with carbon fibers in a carbon matrix for sealing purposes may be a novel approach.

How does the composite seal material compare to traditional seal materials in terms of cost-effectiveness and manufacturing processes?

The article does not provide information on the cost implications or manufacturing processes associated with the composite seal material compared to traditional seal materials.

What are the specific performance advantages of the composite seal material in high-temperature and high-pressure environments?

The article does not detail the specific performance advantages of the composite seal material in extreme operating conditions typically found in gas turbine engines.

Original Abstract Submitted

A gas turbine engine includes a rotor that that has a seal surface, a shaft that has an annular seal channel that opens to the seal surface, and a seal disposed in the annular seal channel for sealing against the seal surface. The seal is made of a composite having carbon fibers disposed in a carbon matrix.
