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 current paper has been written in order to find the best solutions to replace the antitorque rotor of single-rotor helicopters, with removal of its disadvantages through the Coandă Effect. This would significantly increase the flight performance. The research mainly aims at obtaining a controlled lateral force due to Coandă flows through the tail boom, a force which would be useful for the stabilization needed because of the lifting rotor during the flight of single-rotor helicopters.

This paper analyzes a method of evaluating the reliability of the rolling bearing in anti-aircraft guns. In evaluating its reliability, the factors that depend on the operating conditions of the anti-aircraft gun are taken into account, as well as the factors of design, technology, materials and assembly

Using of the flying wing (the UAVs category) in various fields (civilian and military) determine interests sustained of the aerodynamic and trajectory optimizations. The article presents analysis of wing flying performance (in morphing concept) by studying optimizing the maneuvers control and wind tunnel tests.
