Aero engine, stator flow guide assembly and design method of stator flow guide assembly

The invention provides an aero-engine, a stator flow guide assembly and a design method of the stator flow guide assembly. The stator flow guide assembly comprises an outer ring piece, an inner ring piece, a honeycomb piece and a plurality of guide vanes arranged on the outer ring piece and the inner ring piece. The stator flow guide assembly is characterized in that the inner ring piece, the honeycomb piece and the guide vanes are constructed into a whole through an additive manufacturing process, and a part, between the outer surface of the inner ring piece and the honeycomb piece, below a vane runner line is of an inner ring hollow structure, and is filled with an inner ring supporting structure. Due to the optimization of the inner ring structure, and the vane-honeycomb integrated design, the installation step of the inner ring piece is reduced; the additive manufacturing machining process is adopted, so that the manufacturing cost is reduced, the manufacturing period is shortened;and reliability is impro
