Since the first flights in the early 19th century, the humanity fights to understand and enhance the technology and methodology of designing an airplane. The current project will employ the progressive method which has been achieved, during aircraft design toward maximum endurance of electric powered UAV. For this propose, computational tools are going to be explored in order to establish the design procedure, evaluating its capability to deal with a large number of parameters in the conceptual design phase. Naturally, they require that a group of aircraft configurations are going to be created, analyzed and compared, then a specific configuration will be chosen via the optimization process for a fixed requirement and mission profile, considering the cruise performance and consumption analysis for electrical propeller motion system.
