Title
(EN) A TECHNIQUE FOR COOLING A ROOT SIDE OF A PLATFORM OF A TURBOMACHINE PART
(FR) TECHNIQUE DE REFROIDISSEMENT D'UN CÔTÉ DE BASE D'UNE PLATEFORME D'UNE PARTIE DE TURBOMACHINE
Abstract
(EN)
A platform cooling device (10) for directing a cooling fluid onto a root side (52) of a platform (50) of a turbomachine part (2) is presented. The platform cooling device (10) includes a first segment (20) to be positioned at a root (60) of the turbomachine part (2) and a second segment (30), at an angle to the first segment (20), to be positioned at the root side (52) of the platform (50) of the turbomachine part (2). The second segment (30) includes at least one impingement channel (32) having an inlet (34) for receiving at least a part of the cooling fluid and an outlet (36) for releasing the received cooling fluid onto the root side (52) of the platform (50). The first segment (20) and the second segment (30) define a path for the cooling fluid via the impingement channel (32). A turbomachine component (1) including the platform cooling device (10) is also presented.

L'invention concerne un dispositif de refroidissement de plateforme (10) permettant de diriger un fluide de refroidissement sur un côté de base (52) d'une plateforme (50) d'une partie de turbomachine (2). Le dispositif de refroidissement de plateforme (10) comprend un premier segment (20) devant être positionné au niveau d'une base (60) de la partie de turbomachine (2) et un second segment (30), formant un angle avec le premier segment (20), devant être positionné au niveau du côté de base (52) de la plateforme (50) de la partie de turbomachine (2). Le second segment (30) comprend au moins un canal d'impact (32) comprenant une admission (34) permettant de recevoir au moins une partie du fluide de refroidissement et une évacuation (36) destinée à libérer le fluide de refroidissement reçu sur le côté de base (52) de la plateforme (50). Le premier segment (20) et le second segment (30) définissent un trajet pour le fluide de refroidissement par le biais du canal d'impact (32). L'invention concerne également un élément constitutif de turbomachine (1) comprenant le dispositif de refroidissement de plateforme (10).
