A rocket nozzle having an inlet (10), a middle region (20), a throat (30) and an outlet, wherein a ratio of the cross-sectional area of the inlet to the throat is about 1.1. The middle region preferably has a shape which rises to an apex. Such a configuration places particles resulting from combustion on a trajectory which misses the wall of the nozzle at the throat or choke point, thereby decreasing throat erosion/ablation.
L'invention porte sur une buse de tuyère pourvue d'un orifice d'admission (10), d'une région centrale (20), d'un col (30) et d'un orifice d'évacuation, le rapport de la section transversal de l'orifice d'admission par rapport au col étant de 1.1. La région centrale a de préférence une forme montante jusqu'à un apex. Cette configuration permet de placer sur une trajectoire des particules résultant de la combustion, cette trajectoire évitant la paroi de la buse au niveau du col ou point d'étranglement, ce qui réduit l'érosion/ablation du col.
