Abstract

Injecteur (12’) d’un mélange d’air et de carburant pour une chambre de combustion (10) d’une turbomachine, en particulier d’aéronef, comportant un corps (14) comprenant ou définissant au moins un circuit de carburant (16) et au moins un circuit d’air (18), l’injecteur comportant en outre une coupole (20’) située à une extrémité dudit corps et configurée pour délimiter une chambre (22) de prémélange de l’air et du carburant sortant desdits circuits, la coupole comportant une ouverture (24’) de projection d’un cône air-carburant, caractérisé en ce que cette ouverture a un bord périphérique (26’) présentant des encoches (30’). Figure pour l’abrégé : Figure 3Injector (12 ') of an air and fuel mixture for a combustion chamber (10) of a turbomachine, in particular of an aircraft, comprising a body (14) comprising or defining at least one fuel circuit ( 16) and at least one air circuit (18), the injector further comprising a dome (20 ') located at one end of said body and configured to delimit a chamber (22) for premixing the air and the fuel leaving said circuits, the dome comprising an opening (24 ') for projecting an air-fuel cone, characterized in that this opening has a peripheral edge (26') having notches (30 ').
