Abstract
An attachment device for coupling one or more removable turbine components to a carrier of a turbine engine. The attachment device may include a securement structure rotatable about an axis of rotation and including one or more arms for grasping an arm extending from a support structure. A fastener may extend from the support structure and be inserted into a fastener receiving recess in the securement structure for preventing the securement structure from rotating and becoming disengaged from the support structure. The attachment device may also include a fastener retaining device for preventing the fastener, which may be a threaded bolt, from becoming disengaged from the attachment device, traveling downstream in a turbine, and damaging a turbine assembly.
