“…According to Seshaiah et al (2021), a higher value of aerodynamic efficiency allows a lower buoyant force to lift the wings in the air. Thus, fuel consumption is reduced, as explained by Azeez et al (2020) and Gavrilović (2015).…”

This work goal is to achieve a better flight performance and to support the loading of the highest payload possible. The aerodynamics sector works to improve the aircraft aerodynamic efficiency; therefore, the aerodynamicist looks for the best solution to contribute to the aircraft efficiency by reducing drag forces. The induced drag comes from the lift force, it is related to the escape vortices which occur at the wing tips and it is the most relevant drag component. The use of structural components, as winglets, helps to reduce these vortices and the total aircraft drag. In the context of the SAE Brazil AeroDesign competition, the use of these components can support the project requirements due to the regulatory restrictions. The methodology employed was a simulation using the ANSYS CFX® software for wings modeled with different winglet configurations and the same boundary conditions to verify the best application for the studied wing. The winglet dihedral angle was set at 45°, the strings were maintained and the winglet height was used as a parameter. In the simulations, the wing attack angle was varied to obtain the variation of the drag force. With the obtained results, it was possible to verify that the wings lift forces with h=10% of the half-span winglet have lower values of drag force and present higher values of lift force, for all the analyzed angles, with a variation of up to 6 N of lift force, regarding to the wing without winglet. It is concluded the possibility to observe an improvement in the performance of the wing with the application of the winglet, in the above-mentioned context, and the compensation of a higher efficiency can help competition teams to carry more load on the aircraft due to the lift increase, and to assist the aircraft takeoff and landing handling.

“…Therefore, a winglet concept was developed, changing the velocity and pressure field it diffuses the created vortex and reduces the downwash. Consequently, the induced drag is also reduced (JOHANSEN & SORENSEN, 2006;PANAGIOTOU et al 2014).…”

“…Among the passive flow control, the use of winglets 7 – 15 at the wingtips is a most common method, but it is typically used to reduce the induced drag caused by the downwash of wing-tip vortices. Another prominent passive technique is the use of riblets 16 – 21 .…”

This study explores the efficacy of dimples in influencing the aerodynamic performance of a straight rectangular wing. Computational Fluid Dynamics based numerical simulations were performed to model turbulent flow and quantify the forces exerted on the wing. The k-ω Shear-Stress Transport turbulence model was chosen to solve the underlying equations. To ascertain reliability, the results of numerical simulations were compared with both experimental and simulation results of the previous studies. The impact of various dimple configurations, placed at 15%, 50% and 85% of the chord length, on the aerodynamic performance of the wing was investigated. The evaluation involved analyzing the drag coefficient (CD), lift coefficient (CL), lift-to-drag (L/D) ratio, streamlines and the flow field around wing in both chordwise and spanwise directions. The findings indicated that a wing with a dimpled surface could yield a reduced drag coefficient of up to 6.6% compared to the unmodified wing. This reduction is attributed to the dimples ability to sustain attached airflow and delay flow separation. The results demonstrated negligible deviation in the lift coefficient with the incorporation of dimples. The incorporation of dimples on the wing surface has been demonstrated to enhance the aerodynamic performance of lifting surfaces.

“…Energy simulation (ES) is widely used in the field of architecture. Computational fluid dynamics (CFD), a type of computer-aided engineering tool, is also widely used for analyzing houses and offices [ 9 , 10 ], for studying energy-efficient designs for heat pumps [ 11 ], as well as to perform blood flow analyses in medical fields [ 12 ] and aerodynamic analyses of aircraft [ 13 ]. ES is an excellent tool for performing transient calculations for building construction, making it suitable for power consumption estimation.…”
