1. , for separating of a mixer for steam turbines jet engine nozzle, described mixer longitudinally axis (X-X '"'"') comprising:

  • fastening cover (10), described mixer to be connected to the exhaust casing of described nozzle, and lobe structure (20), to mix the air-flow from turbojet engine, described lobe structure has lobe and outside lobe (22 and

         21) inside continuous print, and they circumferentially distribute around the longitudinal axis (X-X '"'"') of described mixer, the feature of described mixer is, described lobe structure (20) is made up of ceramic matric composite, and it also comprises the stiffening device for forming connection between described inner side lobe (22) of described lobe structure, thus described lobe structure is prevented to be out of shape due to the flowing of the air-flow from described turbojet engine, described stiffening device is set to stiffening ring (30), described stiffening ring is secured to each inner side lobe (22) of described lobe structure (20) near the end of described inner side lobe via bolted connection (40), described ring also comprises the streamline device for integrating corresponding joint (40) in the following manner, namely aerodynamic losses is limited, and for described ring provides the intensity of opposing flexural load.
