Abstract (en)
[origin: EP1450005A1] The device has an upstream (32) and downstream annular plate (34) extending radially from upstream and downstream flanges (36, 38) of a lower platform, respectively. An airtight device (42) extends longitudinally between the plates to seal an annular cavity. Bolded links (83) maintain the upstream and downstream plates against the respective flanges. Holes (70) inject cooling air towards a turbine disc.
