Abstract (en)
Compressor stator has upstream ventilation (17,19) and downstream ventilation (18, 20) for air which is hotter than upstream ventilation. It has collar (11) delimiting gas flow vein (12). First portion of collar, subjected to upstream ventilation has annular structure continuous over circumference and in low thermal expansion material. Second portion of collar, subjected to downstream ventilation, has structure formed from juxtaposed angular sectors in material with more significant thermal expansion.
