1. An apparatus for an aircraft propulsion system, comprising:
a duct structure including a transition duct, an inlet duct and a bypass duct, the duct structure configured as a monolithic body;
the transition duct including an inlet, a first outlet and a second outlet, the transition duct extending longitudinally along a longitudinal centerline from the inlet to the second outlet, the first outlet arranged longitudinally along the longitudinal centerline between the inlet and the second outlet, and a centerline axis of the first outlet angularly offset from the longitudinal centerline;
the inlet duct extending longitudinally along the longitudinal centerline to the inlet; and
the bypass duct extending longitudinally along the longitudinal centerline from the second outlet;
wherein at least a portion of the longitudinal centerline along the bypass duct is non-straight when viewed in a reference plane perpendicular to the centerline axis of the first outlet.
