FIELD: engines and pumps.
SUBSTANCE: turbine ring that makes rotor casing consists of multiple sectors butt-jointed via sealing systems comprising plates arranged between adjacent sectors. Every sealing system consists of rectilinear plates inserted into appropriate mutually independent rectilinear cuts on sector radial sides. Every sealing system arranged between two sectors incorporates first and second plates arranged chevron-like on inner side of aforesaid radial sides of sectors. Second plate is arranged between the point located nearby rear side of every sector and inward it, and the point arranged nearby said first plate, in fact, between its center and two thirds of its length. The other invention of proposed set relates to turbine comprising above described turbine ring.
EFFECT: reduced leaks through intersector space and simple cut design and plates mounting.
