Abstract
An assembly is provided for a turbine engine with an axial centerline. This turbine engine assembly may include a blade outer air seal segment, a linkage and an actuation device. The linkage may include a shaft and a head, where the shaft is connected to the blade outer air seal segment and extends radially outward to the head. The actuation device may include a sloped slide block located radially within and engaged with the head. The actuation device may be configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment.
Claims19
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward to the head;
- and
- an actuation device including a sloped slide block located radially within and engaged with the head, the actuation device configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment;
- wherein the sloped slide block radially tapers as the sloped slide block extends laterally.
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward to the head;
- and
- an actuation device including a sloped slide block located radially within and engaged with the head, the actuation device configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment;
- wherein the sloped slide block is a first sloped slide block, and the head is configured with a second sloped slide block which engages the first sloped slide block.
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward to the head;
- and
- an actuation device including a sloped slide block located radially within and engaged with the head, the actuation device configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment;
- wherein the actuation device further includes a base with a groove, and the sloped slide block is arranged within the groove;
- and
- wherein the sloped slide block is a first sloped slide block, and the base includes a second sloped slide block which engages the first sloped slide block.
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward to the head;
- and
- an actuation device including a sloped slide block located radially within and engaged with the head, the actuation device configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment;
- wherein the actuation device further includes a base with a groove, and the sloped slide block is arranged within the groove;
- and
- wherein the actuation device further includes an actuation arm pivotally attached to the sloped slide block and pivotally attached to the base, and the actuation arm is configured to laterally translate the sloped slide block.
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward to the head;
- an actuation device including a sloped slide block located radially within and engaged with the head, the actuation device configured to laterally translate the sloped slide block and thereby radially move the blade outer air seal segment;
- a second blade outer air seal segment;
- a second linkage including a second shaft and a second head, the second shaft connected to the second blade outer air seal segment and extending radially outward to the second head;
- and
- a second actuation device including a second sloped slide block and an actuation arm, the second sloped slide block is located radially within and engaged with the second head, the second actuation device configured to laterally translate the second sloped slide block and thereby move the second blade outer air seal segment;
- wherein the actuation arm is pivotally attached to the sloped slide block and pivotally attached to the second sloped slide block, and the actuation arm is configured to laterally translate the sloped slide block and the second sloped slide block.
An assembly for a turbine engine with an axial centerline, comprising:
- a blade outer air seal segment;
- a turbine engine case circumscribing the blade outer air seal segment;
- a linkage including a shaft and a head, the shaft connected to the blade outer air seal segment and extending radially outward through the turbine engine case to the head;
- and
- an actuation device including a base, a sloped slide block and an actuation aim;
- the base mounted to the turbine engine case;
- the sloped slide block mated with the base, and the sloped slide block slideably engaged with and radially between the base and the head;
- and
- the actuation arm pivotally attached to the sloped slide block and pivotally attached to the base, and the actuation arm is configured to laterally translate the sloped slide block and thereby move the blade outer air seal segment.
