FIELD: engines and pumps.
SUBSTANCE: mixer for nozzle with separated flow of turbojet engine comprises vane structure arranged in lengthwise direction and made from composite material with ceramic matrix, retaining ring and appliances of rigidity. Vane structure serves to mix flows coming from turbojet engine and comprises sets of inner and outer vanes distributed around the mixer lengthwise axis. Metal retaining ring is intended for fastening said mixer to nozzle exit casing. Appliances of rigidity joint inner vanes to add to resistance against pressure caused by flows from turbojet engine. Vane structure is jointed to retaining ring by means of flexible fastening grips to compensate for difference in thermal expansion of retaining ring and vane structure. The other invention of the set relates to turbojet engine that comprises above described nozzle with said mixer.
EFFECT: lower weight, higher rigidity.
