Abstract
L'invention concerne l'étanchéité dans une turbomachine à gaz. Des passages (52) pour un fluide gazeux barrière sont prévus à travers une partie de rotor, de même que des moyens de soufflage de ce fluide gazeux. Les passages débouchent, à travers une léchette (41) ou, à proximité de cette léchette, à travers une portion de rotor pourvue de la léchette, de façon que du fluide gazeux soufflé puisse être présent dans une zone (55) située radialement entre un revêtement (46) en matière abradable et la léchette (41) ou ladite portion qui en est pourvue.
