<p>According to the invention, in order to assemble two parts (154, 162) made of materials having different thermal expansion coefficients at their edge portions (154a, 162a) and engaged with each other, the method comprises forming along the thinned edge of one of the parts tabs (170) separated by slots (172) and obtained by cutting or machining the material of the part, and assembling the parts by attaching them (174) to the tabs. The edge portions are mutually engaged in order to be brought into mutual substantially tight contact at the high temperatures achieved during operation. The invention can particularly be used for assembling parts respectively made of a metal and a ceramic-matrix composite material, in particular in an aircraft gas turbine such as the upstream and downstream secondary nozzles.</p> |
