Abstract: A rotary machine, such as a turbomachine of a gas turbine engine, for example, including a rotor and a rotor seal assembly. The rotor is rotatable about a rotational axis and has a rotor seal face. The rotor seal assembly includes a seal body, one or more primary fluid conduits formed in the seal body, and a retraction assembly. The seal body has a seal face and is positionable to form a fluid-bearing gap between the seal face of the seal body and the rotor seal face. The one or more primary fluid conduits are fluidly connected to the fluid-bearing gap to supply a fluid to the fluid-bearing gap. The retraction assembly is connected to the seal body to move the seal body in a retraction direction away from the rotor seal face.

Abstract: A turbomachine includes a rotor shaft having an outer surface, a seal carrier forming an annulus about the rotor shaft, and a seal member. The seal carrier at least partially defines a pressure chamber. The turbomachine further includes a seal member support system including a flex body having a contact portion in contact with the seal carrier, and a flex portion extending from the contact portion towards the outer surface of the rotor shaft. The flex portion is coupled to the seal member and is configured to hold the seal member at a radial distance away from the outer surface of the rotor shaft when a pressure inside the pressure chamber is equal to or below a minimum pressure threshold value, and to flex and move the seal member towards the outer surface of the rotor when the pressure inside the pressure chamber exceeds the minimum pressure threshold value.

Abstract: A seal assembly for a rotary machine, such as a turbine engine, may include a seal rotor comprising a rotor face, a seal slider comprising a slider face, a seal stator, wherein the seal slider is slidably coupled to the seal stator, and wherein the slider face and the rotor face define a primary seal. The seal slider may be configured to slidably engage and retract the slider face with respect to the rotor face. The seal assembly may further include a secondary seal disposed between the seal slider and the seal stator. The secondary seal may be configured to compress and rebound and/or to expand and rebound, over at least a portion of a range of motion of the seal slider.
