Tricoaxial structure type injector for injecting e.g. liquid hydrogen in combustion chamber of rocket engine, has aerodynamic bowl fixed at downstream end of injector body and widened toward inner side of combustion body
The injector (10) has an injector body (12) rotating around a symmetry axis (14). The injector body has an injection element opened at a downstream end of a combustion body (16), where the element is formed of an injection central channel (18) and injection slots (20, 22). The combustion body includes an annular wall (38) centered on the axis and connected to a downstream end of the injector body. An aerodynamic bowl (40) centered at the axis is fixed at the downstream end of the injector body and widened toward inner side of the combustion body.
