摘要

The propulsive concept of Goldschmied- Skaleski proposes simultaneously the drag reduction of an aerodynamic body and the increase of propulsive efficiency through the ingestion and control of the boundary layer. In an effort to increase the technology readiness level of this concept, the authors apply it to the aerodynamic design of a main landing gear wheel fairing of a racer aircraft named Anequim designed to be the fastest piston engine aircraft in the world. Over this test model, a design of experiments methodology was used with almost 2,700 different geometries to study the influence of specific design parameters over the overall drag force. This study was carried out using 2-D and 3-D CFD simulations provided by commercial software. The relevant design parameters were identified using a correlation matrix of the 2-D results. Finally, in order to verify the proposed methodology a 3-D CFD simulation was performed. The results show a reduction on the drag force of the wheel fairing for an operational range of the suction system and also an increase on the axial force due to the fan thrust.
