Abstract:
In order to assemble together two parts (154, 162) of materials having different coefficients of expansion via mutually engaged edge portions (154a, 162a), tongues (170) are formed in the thinned edge of one of the parts, the tongues being separated by slots (172) obtained by cutting or machining the material of the part, and the parts are assembled together by fastening (174) via the tongues. The edge portions are mutually engaged in such a manner as to be in substantially leaktight contact at the high temperatures encountered in operation. The method is applicable in particular to assembling together parts made respectively of metal and of ceramic composite material, in particular in an aviation gas turbine, for example, upstream and downstream secondary nozzles.
