FIELD: machine building.
SUBSTANCE: invention relates to a turbine containing fixed guide vanes of a turbine of a composite with a ceramic matrix, attached to the turbine housing. Turbine contains a plurality of fixed guide vanes, a support element and a housing. Set of fixed guide vanes of the turbine are located around the axis of the jet engine for the formation of a nozzle of the turbine apparatus and are made of a composite with a ceramic matrix, and each of them contains a part with an aerodynamic profile, continuing radially relative to the axis of the jet engine, the outer bandage part, continuing continuously from the radially outer end of the part with the aerodynamic profile in the direction of the circumference in one direction relative to the axis of the jet engine, and the inner banding part, continuing continuously from the radially inner end of the part with the aerodynamic profile in the direction along the circumference in the same direction. Support element is made of metal material and contains a front hook part for coupling with the front section of the outer bandage part located on the gas input side, and a rear hook portion for coupling with the rear portion of the outer bandage portion located on the gas outlet side. Turbine housing is made of a metal material to which the supporting element is attached.
EFFECT: supporting element has grooves in the front hook-shaped part and the rear hook-shaped part to enable the front section to be inserted respectively and the rear portion of the outer bandage portion in the circumferential direction to the grooves, thereby providing adhesion of the outer bandage portion to the support member.
