<p>#CMT# #/CMT# The blading (10) has a coaxial annular inner platform (12) and an annular outer platform interconnected by radial blades (11). The inner platform includes an annular radial partition (120) and a blade support crown (121) extending from either side of a radially outer end of the partition. An annular sealing plate (20) is brought back on the inner platform at an upstream side of the radial partition with respect to an air flow. The sealing plate is attached to the blade support crown, where the sealing plate includes a circumferential groove. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing the blading. #CMT#USE : #/CMT# Fixed blading for air flow distribution in a low pressure turbine of a turboshaft engine. #CMT#ADVANTAGE : #/CMT# The annular sealing plate is brought back on the inner platform at the upstream side of the radial partition with respect to the air flow, thus enabling to shorten and lighten the sealing plate, so as to reduce the production cost of the sealing plate while enabling to avoid the step to undulate the sealing plate to reduce its rigidity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial perspective view of a blading. 10 : Blading 11 : Radial blades 12 : Annular inner platform 20 : Annular sealing plate 120 : Radial annular partition 121 : Blade support crown.</p> |
