FIELD: transport.SUBSTANCE: this circular sector has inner shell sector, set of blades and assy that makes the outer shell sector. Blades are secured to said assy making the outer shell sector and to inner shell sector. Said assy making the outer shell sector comprises multiple elementary sectors spaced apart along the assy tangential direction and damping wedges. Every damping wedge is fitted between two elementary sectors arranged directly along said tangential direction. Profile of every damping wedge approximates to that of elementary sectors. Damping wedges extend along inclined position of aforesaid assy. Another invention of this set relates to turbomachine including said blade circular sector.EFFECT: better damping properties.5 cl, 8 dwg |
