Reflexed airfoil4/30/2023 ![]() Equations of motion for FWMAV have been written in a body axis system yielding a 6-DOF model. Rate derivatives and elevon control derivatives have also been calculated. Static aerodynamic coefficients were evaluated using wind tunnel tests conducted at cruise velocity of 20 m/s for varying angles of attack. The vehicle was fabricated using hot wire machine with EPP styrofoam of density 50 Kg/ m 3. Elevon control surfaces have been designed and evaluated for longitudinal and lateral control. Eppler-387 proved to be the most efficient reflexed airfoil and therefore was selected for fabrication and further flight testing of vehicle. Airfoil aerodynamic parameters have been calculated using a potential flow solver for ten candidate airfoils. The selection procedure of airfoil has been developed by considering parameters related to aerodynamic efficiency and flight stability.
