The invention relates to a turbo-machine (1) comprising a rotor (25) that extends along a rotational axis (15). Said rotor (25) has a peripheral surface (31) which is defined by the outer radial delimitation surface of the rotor (25) and has a receiving structure (33) as well as a first moving blade (13A) and a second moving blade (13B). Each moving blade comprises a blade footing (43A, 43B) and a blade platform (17A, 17B). The blade platform (17A) of the first moving blade (13A) and the blade platform (17B) of the second moving blade (13B) border one another, and a gap (49) is formed between the blade platforms (17A, 17B) and the peripheral surface (31). A sealing system (51) is provided in the gap (49) on the peripheral surface (31).

L'invention concerne une turbomachine (1) comportant un rotor (25) s'étendant le long d'un axe de rotation (15). Ledit rotor (25) comprend une surface périphérique (31) définie par la surface de délimitation du rotor (25), ainsi qu'une structure de réception (33) et une première aube mobile (13A) et une seconde aube mobile (13B), qui présentent chacune une emplanture (43A,43B) et une plate-forme (17A,17B). La plate-forme (17A) de la première aube mobile (13A) et celle (17B) de la seconde aube mobile (13B) se jouxtent. Un espace intermédiaire (49) est formé entre les plates-formes (17A,17B) et la surface périphérique (31). Un système d'étanchéité (51) est prévu sur la surface périphérique (31), dans l'espace intermédiaire (49).
