Abstract:

The development of unmanned aerial vehicles (UAV), in industry and research centers, has increased substantially in recent years. The configurations and features of the new UAVs are limited only by the imagination of designers. So, the use of techniques based on design optimization algorithms is an essential tool for making decisions during the conceptual design phase. This work formulates the application of a multi-objective design methodology for the conceptual design of a C wing tip for a flying wing powered by an electric power plant. The design objective is to propose C wing geometric configurations regarding flying wing dynamic characteristics, expressed in terms of the longitudinal flying qualities. The multi-objective optimization will be performed using a multi-objective evolutionary algorithm (AEM), which uses the so-called meta-heuristic Differential Evolution. The maximum between the short and long frequencies and the time that would take an unstable aircraft to duplicate the amplitude of the oscillations, after being disturbed, are the optimization objectives. The selection of the solutions that represent the best compromise between the optimization goals is based on Pareto dominance. It is expected that the family of solutions provided by the proposed design method for the C wing may help designers to tailor the appropriate latency of the real-time control system to command the flying wing.
