GUIDE APPARATUS DIVIDED INTO SECTORS FOR TURBOMACHINE, LOW-PRESSURE TURBINE AND TURBOMACHINE Russian patent published in 2013 - IPC F01D9/04 F01D11/00 

FIELD: machine building.

SUBSTANCE: guide apparatus of a turbomachine, which is divided into sectors, includes internal and external platforms connected to each other with radial blades. Internal platform is connected to a radial partition wall carrying the elements from abrasive material. Elements from abrasive material are fixed on an annular support divided into sectors, which has a slot opening radially outwards, into which internal periphery of partition wall is introduced. Each sector of the support on one of its external ends includes a hole for installation on the partition wall of a guide apparatus sector. On the other end of its external ends the support sector includes devices forming a stop in circumferential direction and guide apparatus sectors interacting with the partition wall sector provide retention towards circumferential direction of the partition wall relative to the support sector. Other inventions of the group refer to a low-pressure turbine of a turbomachine and a turbomachine containing the above guide apparatus divided into sectors.

EFFECT: inventions allow simplifying replacement of worn-out elements from abrasive material, as well as production of a guide apparatus of a turbomachine.
