Abstract

La présente invention concerne une turbomachine (1) comprenant au moins deux hélices non carénées (10, 11) contrarotatives et présentant des pales (20, 21) s'étendant radialement, dont une hélice amont (10) et une hélice aval (11), caractérisé en ce que : - l'hélice amont (10) présente un diamètre inférieur à l'hélice aval (11); et - l'hélice amont (10) présente une vitesse de rotation supérieure à l'hélice aval (11).
