A centerbody for a tangential entry nozzle having a longitudinal axis and a radially outer surface including a frustum portion defining the outer surface of a frustum that is coaxial with the longitudinal axis and flares toward the frustum base thereof, and a curved portion which is integral with the frustum portion and preferably defines a portion of the surface generated by rotating a circle which is tangent to the frustum portion and has a center which lies radially outward thereof about the longitudinal axis. The centerbody has a base which includes at least one air supply port extending therethrough, and an internal passageway. The frustum portion tapers towards a discharge orifice of the internal passageway, and terminates at the plane in which the discharge orifice is located. A fuel-lance that is coaxial with the axis and extends through the base and terminates within the internal passageway provides fuel to the air flow in the centerbody.

Corps central pour injecteur avec entrée tangentielle ayant un axe longitudinal et une surface extérieur radiale comprenant un tronc définissant la surface extérieure d'un tronc coaxial par rapport à l'axe longitudinal et qui s'évase vers la base du cône, et une partie courbée faisant partie intégrante du cône et définit préférablement une partie de la surface générée par la rotation d'un cercle qui fait tangente au cône, et comporte un centre qui fait saillie radialement autour de l'axe longitudinal. Le corps central a une base qui comprend au moins un orifice d'alimentation en air se prolongeant à travers de celle-ci, ainsi qu'un passage interne. Le cône va en s'amincissant vers l'orifice de sortie du passage interne et se termine au plan sur lequel est défini l'orifice d'évacuation. Une lance de carburant qui est coaxiale par rapport à l'axe et se prolonge à travers la base et se termine dans le passage interne alimente le jet d'air en carburant dans le corps central.
