Abstract

La soufflante radiale décrite comprend un logement hélicoïdal (1) pourvu d'une languette (2), ainsi que des ouvertures d'entrée et une ouverture de sortie (5). Dans le logement hélicoïdal (1) est monté un rotor (6) pourvu d'un arbre (7) portant un disque. Sur la périphérie des surfaces latérales du disque sont montées des ailettes (10) formant des cavités (11) internes au rotor. Le logement hélicoïdal (1) est pourvu de parois de séparation montées en porte à faux sur le logement. Les extrémités libres (19) des parois de séparation sont disposées dans les cavités (11) internes au rotor avec un décalage (alpha1) par rapport à la languette (2) dans la direction opposée à la direction de rotation du rotor (6). Les espaces libres (delta1) compris entre la languette (2) et les bords de fuite (12) des ailettes proximales (10) sont égaux à 0,03 - 0,2 fois la distance (R1) comprise entre l'axe (O1 - O1) de rotation du rotor (6) et le bord de fuite (12) de l'ailette (10).
