TURBINE GUIDE VANES FOR GAS TURBINE ENGINE, SECTOR OF GUIDE VANES, CONTINUOUS CIRCULAR BRACKET, LOW PRESSURE TURBINE OF GAS TURBINE ENGINE AND GAS TURBINE ENGINE Russian patent published in 2014 - IPC F01D9/04 F01D11/00 

FIELD: engines and pumps.

SUBSTANCE: each sector of an internal platform is connected to a sector of a radial partition. The internal peripheral part of each sector of the partition is equipped with teeth and comprises solid parts that alternate with parts that contain grooves. Elements from worn material are fixed on the continuous circular bracket, comprising facilities of fixation on partition sectors. The bracket is made as capable of rotation and turning in the circumferential direction between the assembly position and the disassembly position and the blocking position, in which fixation facilities interact with solid parts of partition sectors for provision of bracket retention on the partition. Fixation facilities form sections of a circular groove opening in the radial direction to outside, in which solid parts of partition sectors are placed in the blocking position. Other inventions of the group relate to the sector and the continuous circular bracket of the guide vanes specified above, and also to the lower pressure turbine and the gas turbine engine including such guide vanes.

EFFECT: group of inventions makes it possible to simplify manufacturing of guide vanes sectors.
