Fixed vane for distributing air flow in low pressure turbine of turbomachine of aircraft, has annular sealing plate extended in upstream of platform with respect to air flow in vane and integrally formed with support crown of blades

摘要

The vane (10) has an annular lower platform (12) on which a set of radial blades (11) is fixed. The platform includes a support crown (121) of the blades. An annular sealing plate (20) is extended in upstream of the platform with respect to a flow of air in the vane. The sealing plate is integrally formed with a support crown of the blades. The sealing plate is an annular protuberance toward upstream of the support crown of the blades, where the sealing plate is formed with a circumferential groove (22). An independent claim is also included for a method for manufacturing a fixed air flow distributing vane.
