| Zusammenfassung: | The mixer (7) has a conical ring (8) including scoops (9) provided with recesses (10) extending through the ring, and scuttles (11) for covering the recesses. The scuttles are connected at edges of the recesses while converging towards the ring in a direction downstream of a conduit, and forming an opening with the ring in a direction upstream of the conduit. The recesses are narrowed in the downstream direction of the conduit. The cowling is formed in a central section of the scoop at an angle ranging between 18 and 61 degrees with respect to an axial direction of the nozzle.
Le mélangeur (7) comprend une virole (8) plate, de forme généralement conique, pourvu d'écopes (9) comprenant un évidement (10) et un capotage (11 ou 12) captant une partie d'un flux gazeux et le canalisant pour le précipiter dans un flux voisin au-delà du mélangeur (7). Les caractéristiques de mélange sont excellentes. Application aux turboréacteurs à double flux. |
