Annular stator blade platform for low pressure turbine in a gas turbine engine

摘要

The platform has a downstream part for supporting a fixed blade (14) delimiting radially an aerodynamic channel (24). The channel extends longitudinally between a leading edge (14a) of the fixed blade and a trailing edge (12a) of a mobile blade (12). An upstream part extends longitudinally around the leading edge of the fixed blade towards the trailing edge to increase the length of the channel. An Independent claim is also included for a guide vane of a low pressure turbine.
