Summary

The subject of the study is the optimization of static port placement on aircraft fuselage using computational fluid dynamics (CFD) to minimize aerodynamic errors, particularly under propeller-induced flow influences. The paper addresses the challenges in traditional wind tunnel testing, which is resource-intensive, and proposes numerical modeling as an efficient alternative. The purpose is to develop a methodology for simulating static port performance in various flight regimes, identify high-error zones, and recommend low-error installation points. Methodology: the study employs the finite volume method in OpenFOAM with a modified solver to simulate incompressible turbulent flow and propeller effect via an actuator disk. Results were overlaid using a multiplication-normalization method to localize optimal zones. Results: distributions showed significant propeller influence, with asymmetric error zones on the fuselage. Optimal areas (errors <2.5-5%) were identified, excluding engine, propeller, and structural disturbances. Flight tests confirmed the numerical simulation. Conclusions: the approach reduces experimental needs, enhances accuracy via software compensation, and is applicable to small aircraft design. It highlights “propeller mode” impacts and its asymmetry, offering practical guidelines for static port installation.
