Zusammenfassung:	An attritable engine (100) includes an engine case (105), which includes an outer wall (110) and a fuel rail (120) integral with the outer wall (110). The fuel rail (120) includes a fuel line (121) integral with the outer wall (110), a fuel ring (124) configured to receive fuel from the fuel line (121), and an injector throat (126) configured to receive aerated fuel from the fuel ring (124). The engine case (105) includes counter distortion webbing (130) defining the injector throat (126) and is integral with the fuel rail (120) and the outer wall (110). The engine case (105) includes a combustion chamber (140) configured to receive fuel from the injector throat (126).
