    Abstract: A turbine engine comprising an engine core having a rotor and a stator, and a floating seal assembly sealing at least portions of the rotor and the stator relative to a higher-pressure area and a lower-pressure area. The floating seal assembly can comprise a carriage assembly at least partially defining a seal cavity and a seal body floating within the seal cavity. The floating seal assembly can further include at least one of a seal located between the seal body and the carriage assembly, and a seal face located between the seal body and the carriage assembly.

    Abstract: A seal assembly for a turbomachine includes a rotating component, a non-rotating component having a ring carrier, a face seal ring, and a joint disposed between the ring carrier and the non-rotating component. The non-rotating component is arranged with the rotating component at a sealing interface. The joint is capable of linear and tilt displacement to allow the non-rotating component to displace with respect to the rotating component. The sealing interface defines a gap between the face seal ring and the rotating component. The seal assembly also includes at least one damping element arranged with the ring carrier for maintaining the seal assembly centrally in a radial direction in the turbomachine. Further, the damping element(s) includes at least one mass element.

    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 of a rotary includes a radially oriented plate that axially opposes a front and rear support plates of a stator interface. The seal assembly also includes a film-riding shoe coupled with the radially oriented plate. The shoe forms a shoe fluid bearing between the shoe and a rotating component responsive to rotation of the rotating component and pressurization of fluid in the rotary machine upstream of the stator interface. One or more of the stator interface or the film-riding shoe includes one or more ports or pathways through which higher-pressure fluid upstream of the stator housing in the rotary machine flows to form an aft axial fluid bearing between the radially oriented plate and the rear support plate of the stator interface.

    Abstract: A face seal assembly including a thermal fluid circuit, a turbomachine including the face seal assembly and a method of operating the turbomachine are disclosed. The face seal assembly includes a seal ring including a seal bearing face, at least one internal cavity including a cavity inlet and a cavity outlet. The face seal assembly further including a fluid inlet channel in fluid communication with the cavity inlet of the at least one internal cavity and a pressurized fluid and a fluid outlet port in fluid communication with the cavity outlet of the at least one internal cavity. The at least one internal cavity, the fluid inlet channel and the fluid outlet port define a thermal fluid circuit providing thermal management of the seal ring. In the turbomachine, the face seal assembly is disposed between a stationary component and a rotating component including a rotating component bearing face.

    Abstract: A seal assembly for a rotary machine is positioned between a rotating component and a stationary component of the rotary machine. The seal assembly includes a seal bearing face that opposes the rotating component and a slide device. The slide device is positioned between different fluid pressure volumes in the rotary machine. The slide device axially moves toward the rotating component responsive to pressurization of the rotary machine. The slide device includes cross-over ports and the seal bearing face includes feed ports. The feed ports extend through the seal bearing face to form an aerostatic portion of a film bearing between the seal bearing face and the rotating component. The seal bearing face and/or the rotating component is a non-planar surface that, during rotating motion of the rotating component, forms an aerodynamic portion of the film bearing between the seal bearing face and the rotating component.
