The biological flight involves the movement of a wing (lift surface) in viscous medium and it generates lift and resistance for going forward through friction compared to Reynolds number. The morphing concept is generally based on optimizing the aerodynamic form during the mission so it can execute a maneuver flight. This article desires a short passage through the mathematical aspect in 2D of the morphing profile concept.

In the field of UAV, information processing centers most often materialize through ground control stations (GCS) that are used in various variants from simple commercial products in the form of tablets or radio control stations for controlling the vector within the visual range at low altitudes and autonomies, or portable, fixed or self-propelled technologies for missions beyond the visual range at high altitudes and autonomies. The article wants an overview of the theoretical bases on the construction and operation of GCS and aspects of flight mission debriefing using freeware tools.

The missions of small flying wing UAVs require maneuver capabilities as well as optimal flight performance to balance the low operating and manufacturing costs. The basic principles in designing aviation structures must be readjusted due to the innovative concepts regarding the use of advanced materials as well as to the perspectives of using alternative energy aboard UAVs. The current paper is a synthesis of the 2D and 3D aerodynamic analysis of small swept flying wing UAVs that offers a global image of the possibilities of a multidimension optimization (miniaturization-scalability, payload-flexibility, minimum performances requirements).
