Aviation is the domain with one of the greatest technical developments. Thus the emergence and development at the consumer level of commercial UAVs has put the entire aerospace industry and national security system in front of a fulfilled fact. These unmanned human onboard systems and the continuous development of hardware and software systems are currently creating one of the biggest challenges: integration in airspace. The article reviews the risks, threats and concepts of illegal use of the drones.

Abstract:The multi-copter UAV landing gear is used for ground station and shock damping for landings. The materials used in the construction of landing gears are selected by using a simple criterion: minimal mass versus maxim resistance at shocks. Article contains an evaluation of a kinematics mechanism quadrilateral landing gear is mounted on a multicopter.
