GAS TURBINE ENGINE AND SEAL ASSEMBLY THEREFORE

摘要

The present disclosure relates generally to a hydrostatic advanced low leakage seal having a shoe supported by at least two beams. An anti-vibration beam spacer is disposed in contact with two adjacent beams and operative to mitigate an externally induced vibratory response of the beams.

主权项

1. A seal assembly disposed between a stator and a rotor, the seal assembly comprising:
a hydrostatic advanced low leakage seal including:
a base;a shoe; anda spring element including a first spring element end operatively coupled to the base and a second spring element end operatively coupled to the shoe, the spring element further comprising:
a first beam extending between the first and second spring element ends; anda second beam extending between the first and second spring element ends and radially spaced from the first beam; anda first beam spacer disposed in contact with the first beam and the second beam and operative to mitigate an externally induced vibratory response of the spring element;wherein the base is operatively coupled to one of the stator and the rotor.
