Mini airplane: Design, aerodynamic modeling and stability

Abstract

This paper presents the development of a mini airplane UAV, focusing on the aerodynamic design, modeling and stability. Mathematical model of the vehicle is obtained using the Euler-Lagrange formulation and includes aerodynamic parameters of the design. For the stability, a classic control law is proposed taking in account the aerodynamic parameters and the sensors bandwidth implemented in the aircraft. Simulation results are shown for the closed-loop system of the vehicle. Finally, aerodynamic design and avionics are based on flying and handling qualities for having a mini airplane that performs a reliable and stable flight.
