FIELD: engines and pumps.SUBSTANCE: gas turbine engine element comprises outer ring including inlet with path made of abradable material in direct contact with inner surface of said ring and outlet whereto stator blades are connected. Stator blades are furnished with flat beds separated from outer ring. Outlet edge of abradable path is located nearby set of outlets of said flat beds. In making said element, stator blades are jointed with aforesaid ring to produce, in fact, continuous annular space inside said outer ring. Then, abradable material is applied inside the ring using the region intended for forming edge of said abradable path. One more invention relates to gas turbine engine incorporating said element.EFFECT: simplified design, killed vibrations.10 cl, 3 dwg |
