Reliability Synthesis for UAV Flight Control System

This paper presents the models and methods for reliability synthesis for components of UAV flight control system: flight computer and navigation system. The developed reliability models depict different variants of faulttolerant designs including designes for systems with complex reliability behavior. They have a high level of adequacy, since effectiveness of detection and switching devices was taken into account. Based on the models, we proposed the reliability synthesis methods for flight control system components that allows making reasonable design decisions. As an example of using these methods, the reliability requirements and recommendations for rational choice of fault-tolerant designs were developed to meet required reliability level of UAV flight computer and navigation system.
