  • Patent number: 11092039
    Abstract: Embodiments of the present disclosure can provide an apparatus for circumferentially separating turbine blades. An apparatus according to the present disclosure may include: a length-adjustable elongate member having opposing first and second ends; a first clasp coupled to the first end of the length-adjustable elongate member, the first clasp shaped to at least partially engage an airfoil profile of a first turbine blade positioned circumferentially adjacent to a dovetail slot, relative to a centerline axis of the turbomachine; and a second clasp coupled to the second end of the length-adjustable elongate member, the second clasp shaped to at least partially engage an airfoil profile of a second turbine blade circumferentially positioned adjacent to the dovetail slot, the first and second turbine blades being circumferentially adjacent to the dovetail slot at opposing circumferential ends thereof.

  • Patent number: 11014205
    Abstract: Embodiments of the present disclosure relate to the installation or removal of turbine blades at a turbine blade base thereof. An apparatus according to the present disclosure can include: an operative head configured to engage an axial sidewall of a turbine blade base; and a mount removably coupled to a portion of a turbomachine assembly by a coupler, wherein the operative head is slidably coupled to the mount such that the operative selectively engages the axial sidewall of the turbine blade base, and wherein the operative head is shaped to impart an axial and a circumferential force against the turbine blade base.
