FLEXIBLE THRUST LINKS FOR FIXATION OF PARTS FROM COMPOSITE MATERIALS WITH CERAMIC MATRIX Russian patent published in 2013 - IPC F02K1/04 F02K1/80 

FIELD: engines and pumps.

SUBSTANCE: output device of an aviation engine comprises a metal circular part and a part of the output device from a composite material with a ceramic matrix, which has the shape of the revolution solid in the upper part along the flow. The part of the output device is installed on the circular part with the help of elastic fastening legs. Each fastening leg has the first end fixed on the circular part and the second end fixed on the upper section of the output device part in direction of the flow. At the same time in one of versions of output device realisation each fastening leg comprises an axial thrust element that diverts radially from the second end of the leg and arranged opposite to the first end, and a radial thrust element at the level of the second end of the leg arranged above the first end in the radial direction. In another version of realisation a part of the output device is installed downstream the circular part, and the edge of the upper part of the output in direction of the source is maintained in the axial direction opposite to the outer radial surface of the circular part, and in the radial one - above the first end of the fastening legs. The first end of each fastening leg comprises a leg stretching along the axis in direction from the circular part. Another invention of the group relates to an aviation engine comprising the above output device.

EFFECT: inventions make it possible to increase reliability of a fixation unit of an output device without increase of its weight.
