Abstract:
A turbine ( 1 ) for a turbine engine, the turbine comprising a casing ( 4 ) and a turbine nozzle stage ( 2 ), the nozzle stage ( 2 ) of the turbine ( 1 ) being made of a ceramic matrix composite material and comprising a plurality of annular sectors ( 20 ) forming a ring presenting an inner shroud ( 240 ) and an outer shroud ( 260 ), each annular sector ( 20 ) having both an inner platform ( 24 ) forming a portion of the inner shroud ( 240 ) and an outer platform ( 26 ) forming a portion of the outer shroud ( 260 ), and at least one airfoil ( 28 ) extending between the outer platform ( 26 ) and the inner platform ( 24 ) and secured thereto, said airfoil ( 28 ) presenting a hollow profile defining an inside housing ( 280 ) extending between the inner platform ( 24 ) and the outer platform ( 26 ), and each of the inner and outer platforms ( 26, 28 ) presenting an orifice ( 245, 265 ) communicating with said inside housing ( 280 ) of the airfoil ( 28 ). Each annular sector ( 20 ) of the nozzle stage ( 2 ) includes at least one strut ( 6 ) passing through said orifices ( 245, 265 ) in the platforms and through the inside housing ( 280 ) of said at least one airfoil ( 28 ), said strut firstly being fastened to said casing ( 4 ) and secondly being in connection with said annular sector ( 20 ).

Claim (Index 5):
A turbine ( 1 ) for a turbine engine, the turbine comprising a casing ( 4 ) and a turbine nozzle stage ( 2 ), the nozzle stage ( 2 ) of the turbine ( 1 ) being made of a ceramic matrix composite material and comprising a plurality of annular sectors ( 20 ) forming a ring presenting an inner shroud ( 240 ) and an outer shroud ( 260 ), each annular sector ( 20 ) having both an inner platform ( 24 ) forming a portion of the inner shroud ( 240 ) and an outer platform ( 26 ) forming a portion of the outer shroud ( 260 ), and at least one airfoil ( 28 ) extending between the outer platform ( 26 ) and the inner platform ( 24 ) and secured thereto, said airfoil ( 28 ) presenting a hollow profile defining an inside housing ( 280 ) extending between the inner platform ( 24 ) and the outer platform ( 26 ), and each of the inner and outer platforms ( 24 ,  26 ) presenting an orifice ( 245 ,  265 ) communicating with said inside housing ( 280 ) of the airfoil ( 28 );\n the turbine being characterized in that each annular sector ( 20 ) of the nozzle stage ( 2 ) includes at least one strut ( 6 ) passing through said orifices ( 245 ,  265 ) in the platforms and through the inside housing ( 280 ) of said at least one airfoil ( 28 ), said strut firstly being fastened to said casing ( 4 ) and secondly being in connection with said annular sector ( 20 ); and first and second pegs ( 63 ), the inner platform ( 24 ) having a portion ( 242 ) projecting towards the inside of the ring of the nozzle stage ( 2 ) and presenting both a circular first orifice ( 244 ) configured to receive the first peg ( 63 ) and an oblong second orifice configured to receive the second peg, the strut ( 6 ) further including both a circular third orifice ( 66 ) and a circular fourth orifice, the first peg ( 63 ) passing through the first orifice ( 244 ) and the third orifice ( 66 ), and the second peg passing through the second orifice and the fourth orifice in order to fasten the strut ( 6 ) to the annular sector ( 20 ).
