Abstract (en)
[origin: EP1580401A2] The two parts (1, 2) are designed so that when the turbine is in the idle state a gap (3) is present between the two passages (1a, 2a) and when the turbine is working this gap is sealed as a result of different thermal expansion of these parts. The first part is a heat shield comprising a material with a greater thermal expansion coefficient than the second part, which is a support structure for a gas turbine.
