The Analysis of Aerodynamic Parameters of a Solar Plane with Usage of CFD Modeling

The world today faces many difficult challenges, including environmental pollution, climate changes and energy crisis. Due to this the usage of the renewable energy, especially the solar one is more and more popular. Not only to the energetic purposes but also to provide the power source in transportation. Airplanes powered by solar energy via photovoltaic panels are a relatively new segment for aerospace industry, but they quickly gained significant interest. These planes convert solar energy directly into electrical energy by means of solar cells. Surplus energy generated by them can be storage in batteries which allows to carry out the flight also at night. For further development of this technology computational fluid dynamic (CFD) might be used. This technique allows to precisely predict and confirm airplane flight characteristics. Moreover, it makes the whole process high-performing and cost-effective. The aim of airplanes simulations is to maximize lift to drag coefficient (L/D). The efficient aerodynamic performance also might be provided by suitable selection of the wing airfoil. This study shows simulations carried out in ANSYS Fluent 18.2/19.0 for 2D model of airfoil and 3D models of the whole plane. The lift and drag coefficients and forces were calculated. Results from FLUENT are mainly presented in terms of velocity and pressure contours. Keywords - CFD Modeling, Aerodynamic Parameters, Photovoltaic, Solar Aircrafts.
