A thrust assembly motor is described, which can be used in a distributed electric propulsion system. The thrust assembly motor may include a revolved-wedge shaped ring on a leading edge of a motor stator, with a row of axial stator blades extending therefrom. The revolved-wedge shaped ring provides a mounting surface for the axial stator blade row while also controlling the ratio of airflow mass entering the outer gap versus the inner gap. The axial stator blade row, mounted to the revolved-wedge shaped ring, is configured to convert tangential kinetic energy (i.e., associated with a velocity component of the airflow) in the cooling airflow aft of the cooling fan rotors into static pressure rise after interaction with the axial stator blade row, during flight of the hybrid-propulsion aircraft.
