SEAL SUPPORT ASSEMBLY FOR A TURBINE ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240318567 titled 'SEAL SUPPORT ASSEMBLY FOR A TURBINE ENGINE

Simplified Explanation:

This patent application describes a gas turbine engine with a seal assembly that includes multiple seal segments supported by a carrier, forming fluid bearings with the rotor. A seal support assembly with a tangential spring extension biases the seal segments away from each other in the circumferential direction.

The gas turbine engine includes a rotor, stator with a carrier, and a seal assembly between them.
The seal assembly consists of multiple seal segments supported by the carrier, forming fluid bearings with the rotor.
A seal support assembly with a tangential spring extension biases the seal segments away from each other in the circumferential direction.

Potential Applications:

This technology can be applied in various gas turbine engines used in power generation, aviation, and industrial applications.

Problems Solved:

This innovation addresses issues related to sealing efficiency and rotor-stator interaction in gas turbine engines, improving overall performance and reliability.

Benefits:

The benefits of this technology include enhanced sealing effectiveness, reduced wear on components, and improved efficiency of gas turbine engines.

Commercial Applications:

Potential commercial applications include power generation plants, aircraft engines, and industrial gas turbines. This technology can lead to more reliable and efficient operations in these sectors.

Prior Art:

Prior art related to this technology may include research on seal assemblies in gas turbine engines, rotor-stator interactions, and fluid bearing systems.

Frequently Updated Research:

Researchers may be conducting studies on the optimization of seal assemblies in gas turbine engines, advancements in rotor-stator technology, and the development of more efficient fluid bearing systems.

Questions about Gas Turbine Engine Seal Assembly:

1. How does the tangential spring extension in the seal support assembly improve the performance of the seal segments? 2. What are the specific challenges in designing seal assemblies for gas turbine engines, and how does this innovation address them?

Original Abstract Submitted

a turbine engine is provided. the gas turbine engine includes: a rotor; a stator comprising a carrier; a seal assembly disposed between the rotor and the stator, the seal assembly comprising a plurality of seal segments supported at least in part by the carrier, the plurality of seal segments having a first seal segment and a second seal segment, the first and second seal segments each having a seal face forming a fluid bearing with the rotor; and a seal support assembly comprising a tangential spring extension extending between the first seal segment and the second seal segment for biasing the first seal segment away from the second seal segment in the circumferential direction.
