Abstract: A seal for a rotary machine includes a flexible element extending circumferentially about a rotor and extending generally radially from a first end to a free second end. The flexible element is coupled proximate the first end for rotation with the rotor. The flexible element extends at substantially a first angle between at least an intermediate portion of the flexible element and the free second end when the rotor is operating at less than a critical speed, such that a clearance gap is defined between the free second end and a stationary portion. The seal also includes a retaining plate having a stop that orients the flexible element at a second angle proximate the free second end when the rotor is operating at equal to or greater than the critical speed, such that the flexible element forms a dynamic seal between the rotor and the stationary portion.

The shoe plate is disposed along the rotor. The seal base is disposed radially outward of the shoe plate. At least one intermediate member is coupled to and disposed between the seal base and the shoe plate. The at least one intermediate member includes an actuator portion (302, 402, 702, 902) having first coefficient of thermal expansion and a constrictor portion (304, 404, 704, 904) having a different, second coefficient of thermal expansion. The at least one intermediate member is configured to move the shoe plate from a radially outward position to a radially inward position with respect to the rotor responsive to the at least one intermediate member undergoing a temperature change.

Abstract: A tunneling device includes a body assembly, an expander coupled to the body assembly and extending along a longitudinal axis, and a tip coupled to the expander. The expander is disposed between a force transmitter and the tip. The expander is expandable in a direction perpendicular to the longitudinal axis between a first configuration having a first width measured perpendicular to the longitudinal axis and a second configuration having a second width measured perpendicular to the longitudinal axis. The tip has a width measured perpendicular to the longitudinal axis. The first width of the expander is equal to or less than the width of the tip. The force transmitter is configured to deliver a force through the expander to the tip to move the tip in a direction parallel to the longitudinal axis with the expander in the second configuration.

Abstract: This disclosure is directed to seal assemblies for a turbomachine. The seal assemblies include one or more paired rotors and stators and at least one interface between the rotors and the stators. The components of the stator may be axially and radially movable by vibrations and other mechanical interference. The stators comprise a sealing element, a seal housing, and a stator interface connected to the engine housing. In some examples, seal assembly includes a damping element to isolate one or more of the rotating components from vibrations mechanical interference that might misalign the rotating components from the stationary components while the turbomachine is operational. In some examples, the damping element is positioned between the seal housing and the stator interface. In other examples, the damping element is positioned between the stator interface and the engine housing.

Abstract: A flexible seal for sealing between two adjacent gas turbine components includes a forward end, an aft end axially separated from the forward end, and an intermediate portion between the forward end and the aft end. The intermediate portion defines a continuous curve in the circumferential direction, such that the aft end is circumferentially offset from the forward end. In other cases, the forward and aft ends are axially, radially, and circumferentially offset from one another. A method of sealing using the flexible seal includes inserting, in an axial direction, the aft end of the flexible seal into a recess defined by respective seal slots of two adjacent gas turbine components; and pushing the flexible seal in an axial direction through the recess until the forward end is disposed within the recess.
