Dependability of Avionics Unmanned Aerial Vehicles

The paper considers the dependability of avionics of unmanned aerial vehicles. Different methods of calculating dependability and durability are compared. Methods of calculation using statistical data, an exponential and diffusion-nonmonotonic failure model are presented. The difference in the results is shown when calculating the parameter of the failure flow and the probability of failure-free operation of lambda and the probabilistic-physical methods. Statistical calculation methods are presented. Avionics of modern unmanned aerial vehicles consists of systems with a modern elemental base. The advantage of calculating the durability and reliability of such systems is proved by the probabilistic-physical method. This is important to consider when assigning a warranty life and lifetime. The graphs of the failure intensity and the reliability function measures calculate with help lambda and probabilistic-physical methods of modern navigation systems of unmanned aerial vehicle.
