摘要： An insertion apparatus (102) includes an insertion end (106) positionable within a cavity (146) and configured to travel through the cavity, a steering end (108) opposite the insertion end, and a body (104) extending from the insertion end to the steering end and sized to fit within the cavity. The body includes a plurality of members (110) flexibly coupled together and individually actuated. Each member of the plurality of members includes at least one actuator strand (120). At least one member of the plurality of members has a first configuration in which the at least one member of the plurality of members has a first stiffness and a second configuration in which the at least one member of the plurality of members has a second stiffness greater than the first stiffness. At least a portion of the body is flexible to facilitate travel of the body through the cavity when the at least one member of the plurality of members is in the first configuration. The at least a portion of the body is configured to maintain a selected shape when the at least one member of the plurality of members is in the second configuration.

摘要： An insertion apparatus (134) for use with a rotary machine includes a body (160) extending from an insertion end (146) to a steering end (148) and sized to fit within an annular cavity (138). The body has a first stiffness and curves along a circumference of the annular cavity as the insertion end travels through the annular cavity. The insertion apparatus also includes a stiffener (174) coupled to the body and extending from the steering end to the insertion end. The stiffener has a second stiffness greater than the first stiffness. The insertion apparatus further includes at least one maintenance device (150) coupled to the insertion end of the insertion apparatus and a displacement mechanism (154, 200) configured to adjust a position of the at least one maintenance device relative to the body.

摘要： An inflatable device equipped with a guiding mechanism and methods of installing the inflatable device to form a temporary barrier within a gas turbine engine are provided. In one aspect, an inflatable device includes a backbone (310) and an inflatable bladder (350) connected thereto. The backbone is formed of a flexible and inextensible material. The inflatable bladder is formed of an expandable material. To install the inflatable device within an annular chamber of a gas turbine engine, the backbone is inserted into a first access port of the engine and is moved circumferentially around the annulus of the chamber. The backbone is retrieved through a second access port. The inflatable bladder is moved into position within the chamber by pushing the backbone into the first access port and/or pulling the backbone out of the second access port. When positioned in place, the inflatable bladder is inflated to form an annular seal.

摘要： A system for use in servicing a turbomachine, the system including a first tubular body (128) including an interior channel (132), and a second tubular body (130). The first and second tubular bodies are bendable between a neutral shape and a biased shape. The bodies are bent when in the neutral shape. The second tubular body (130) includes a tip end (146), and the second tubular body (130) is translatable within the interior channel (132). The first tubular body (128) and the second tubular body (130) are rotatable to selectively orient the tip end (146) in multiple degrees of freedom. The system also includes a steering cable (158) extending from the tip end (146), wherein the steering cable (158) biases the tip end (146) for selective orientation in additional degrees of freedom.

摘要： A system for use in servicing a machine. The system includes a tubular assembly (124) comprising a guide tube (126) and a tubular body (128) including a longitudinal axis (136), a tip end (138), a dispensing nozzle (140) defined at the tip end (138), and an interior channel (142) in flow communication with the dispensing nozzle (140). The tubular body (128) is configured to be flexible. An actuator (144) is configured to selectively modify an orientation of the tubular body (128). A reservoir (168) is in flow communication with the interior channel (142). The reservoir (168) is configured to supply a maintenance fluid to the tubular body (128) for discharge from the dispensing nozzle (140).

摘要： A flexible seal 160 for sealing between two adjacent gas turbine components includes a forward end 162, an aft end axially separated from the forward end, and an intermediate portion 164 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.
