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

This abstract first appeared for US patent application 18180449 titled 'SEAL SUPPORT ASSEMBLY FOR A TURBINE ENGINE

The abstract describes a turbine engine with a seal assembly supported by a seal support assembly, including a first seal segment with a seal face, lip assembly, and body.

The turbine engine includes a rotor, stator with a carrier, seal support assembly, and seal assembly.
The seal assembly has a high pressure side and a low pressure side, with multiple seal segments including a first seal segment.
The first seal segment has a seal face that forms a fluid bearing with the rotor, a lip assembly, and a body.
The lip assembly on the high pressure side has a seal lip with a high pressure surface at a first angle and a low pressure surface at a second angle, where the second angle is greater than the first angle.

Potential Applications: - Aerospace industry for aircraft engines - Power generation for gas turbines - Marine propulsion systems

Problems Solved: - Improved sealing efficiency - Enhanced performance and durability - Reduced maintenance and downtime

Benefits: - Increased engine efficiency - Extended component lifespan - Enhanced reliability and safety

Commercial Applications: Title: Advanced Turbine Engine Seal Technology This technology can be utilized in commercial aircraft engines, power plants, and marine vessels, offering improved performance and reliability. Market implications include cost savings, increased efficiency, and competitive advantages in the industry.

Questions about Turbine Engine Seal Technology: 1. How does the seal assembly contribute to the overall efficiency of the turbine engine?

  - The seal assembly reduces leakage and improves the performance of the engine by maintaining proper sealing between the rotor and stator.

2. What are the key advantages of using a lip assembly with high and low pressure surfaces in the seal segment?

  - The lip assembly design allows for effective sealing under varying pressure conditions, enhancing the overall performance and durability of the turbine engine.

Original Abstract Submitted

A turbine engine is provided. The turbine engine includes: a rotor; a stator having a carrier; a seal support assembly coupled to the carrier; and a seal assembly disposed between the rotor and the stator and supported by the seal support assembly, the seal assembly defining a high pressure side and a low pressure side and including a plurality of seal segments, the plurality of seal segments having a first seal segment, the first seal segment having a seal face configured to form a fluid bearing with the rotor, a lip assembly, and a body, the lip assembly positioned on the high pressure side, the lip assembly including a seal lip having a high pressure surface defining a first angle with an axial direction and a low pressure surface defining a second angle with the axial direction, the second angle being greater than the first angle.
