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

This abstract first appeared for US patent application 17994182 titled 'GAS TURBINE ENGINE WITH CARBON/CARBON COMPOSITE PISTON SEAL

Simplified Explanation

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

• Gas turbine engine with a rotor having a seal surface
• Shaft with an annular seal channel opening to the seal surface
• Seal made of composite material with carbon fibers in a carbon matrix

Potential Applications

The technology could be applied in gas turbine engines for aerospace, power generation, and other industrial applications where sealing against high temperatures and pressures is required.

Problems Solved

The composite seal provides improved sealing performance in high-temperature and high-pressure environments, reducing the risk of leakage and increasing engine efficiency.

Benefits

- Enhanced sealing capabilities - Increased engine efficiency - Improved durability and reliability

Potential Commercial Applications

Optimizing Gas Turbine Engine Efficiency with Composite Seals

Possible Prior Art

Prior art may include traditional seals made of materials like rubber or metal, which may not offer the same level of performance in high-temperature and high-pressure conditions.

Unanswered Questions

How does the composite material affect the overall weight of the gas turbine engine?

The article does not provide information on whether the composite seal adds significant weight to the engine, which could impact overall performance and efficiency.

Are there any limitations to the use of composite seals in gas turbine engines?

The article does not address any potential drawbacks or limitations of using composite seals in gas turbine engines, such as compatibility with different fuels or maintenance requirements.

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.
