Abstract

L’invention concerne une roue mobile de turbine de turbomachine, ladite roue mobile comportant un disque (21a) et une pluralité d’aubes comprenant chacune une pale (23) avec un bord d’attaque (A) et un bord de fuite (F), ainsi qu’un pied (24) et une plateforme intérieure (25) séparant la pale (23) et le pied d’aube (24), caractérisée en ce qu’un caisson (27) est porté au moins par ladite plateforme (25), ledit caisson (27) étant adapté pour capter un écoulement secondaire remontant du disque (21a) et/ou du pied (24), ledit caisson (27) étant conformé et dimensionné pour guider et réinjecter ces gaz à travers au moins une ouverture de réinjection (28) que comporte la partie amont de la plateforme (25), avec une orientation et une vitesse voisines de celles des gaz de ladite veine au voisinage de ladite pale (23).
