1. Sector of the turbine guide nozzle (110), containing a segment of the outer platform (102) and a segment of the inner platform (104), between which one or more hollow blades (106) are located, each blade containing a cavity of the trailing edge (116), designed to supply cooling air into it and communicating with several ventilation channels (118) dispersed along the trailing edge of the blade, while these ventilation channels allow to remove part of the cooling air, characterized in that this cavity (116) is connected to the outlet opening (130) air, which is located at the level of the outer platform (102) and allows you to remove part of the cooling air, as well as the fact that the air outlet (130) is made in the part that is attached to the segment of the outer platform (102). ! 2. The turbine nozzle sector according to claim 1, wherein the cross-sectional area of the air outlet (130) is greater than or equal to 2 mm2. ! 3. The turbine nozzle sector according to claim 1, wherein the cross-sectional area of the air outlet (130) is less than or equal to 8 mm2. ! 4. The turbine nozzle sector according to claim 2, wherein the cross-sectional area of the air outlet (130) is less than or equal to 8 mm2. ! 5. The turbine nozzle sector according to claim 1, wherein the part is a metal plate (140) soldered onto a segment of the outer platform (102). ! 6. A manufacturing method according to which: the delivery of the turbine nozzle sector (110) according to any of the previous paragraphs; a protective coating is applied on this sector by saturation from the gas phase in such a way, �
