Abstract
The invention relates to a guide vane system for a turbomachine with at least one guide vane, which can be rotatably mounted around an adjustment axis and is arranged with a radially inner end region in a corresponding recess of an inner ring, wherein the arrangement of the guide vane on the inner ring is secured by a securing element in a form-fitting manner. For an especially advantageous securing of this arrangement, it is provided that the securing element is designed as an oblong element, which is arranged at least in a recess and/or through-opening of the radially inner end region of the guide vane directed in the peripheral direction of the turbomachine and is arranged at least in a recess and/or through-opening of the inner ring directed in the peripheral direction of the turbomachine. In addition, the invention relates to a turbomachine, in particular an aircraft engine, and to a method for assembling a guide vane system.

12. A method for assembling a guide vane system for a turbomachine, comprising the steps of:
-
providing at least one a guide vane that can be rotatably mounted around an adjustment axis and that has a radially inner end region having at least one recess and/or through-opening directed, in the installed position of the guide vane, in the peripheral direction of the turbomachine, providing an inner ring with a recess corresponding to the radially inner end region of the guide vane and with at least one recess and/or through-opening directed in the peripheral direction of the turbomachine, and providing a securing element formed as an oblong element; inserting the radially inner end region of the guide vane into the recess of the inner ring; and inserting the securing element into the recess and/or into the through-opening of the inner ring and into the recess and/or into the through-opening of the guide vane for the form-fitting securing of the arrangement of the guide vane on the inner ring.
