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

This abstract first appeared for US patent application 18357322 titled 'SEAL SUPPORT ASSEMBLY FOR A TURBINE ENGINE

Simplified Explanation

A gas turbine engine with a seal assembly between the rotor and stator is described in the patent application. The seal assembly includes multiple seal segments supported by a carrier, with a tangential spring extension biasing the segments apart.

The gas turbine engine includes a rotor, stator, and seal assembly with multiple seal segments.
The seal segments have seal faces forming fluid bearings with the rotor.
A tangential spring extension biases the seal segments apart in the circumferential direction.

This technology can be utilized in various industries such as aviation, power generation, and marine propulsion systems to enhance the performance and efficiency of gas turbine engines.

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.
