Design and Determination of Aerodynamic Coefficients of a Tail-Sitter Aircraft by Means of CFD Numerical Simulation

Vertical take-off and landing (VTOL) aircraft have become important aerial vehicles for various sectors, such as security, health, commercial sectors. These are capable of operating in different flight modes, allowing the covering most requirements environments. A tail-sitter is a type VTOL vehicle that has ability to take off land vertically on it elevators (its tail) or some rigid support element extends behind trailing edge. Most designed with fixed-wing adaptation rather than having their own design. The design carried out this work had particularity not being an quad-rotor system swept-wing aircraft, but, rather, was made from its geometry twin-rotor configuration. performed using ANSYS SpaceClaim CAD software, numerical analysis performance Fluent CFD software. results were satisfactorily validated empirical correlations calculation polar curve, proposed satisfactory compared those found literature. velocity pressure contours obtained angles attack. force moment coefficients showed trends similar reported
