A potential flow model based on the Douglas–Neumann formulation that can handle interaction problems has been used to analyze the pressure distribution produced by a stator-strut system at the rotor trailing edge. A pressure disturbance sensitivity analysis of some stator and strut parameters was performed and results are discussed in both space and frequency domains. A method for pressure distribution optimization is presented and the outcome analyzed. The optimum stator-strut configuration brings about reduced potential flow disturbances. The pressure wave amplitude produced by the strut is lowered to the same order of magnitude as that induced by the stator alone.
