Strilets V. Information technology of aircraft system diagnosis under input data uncertainty

The research object is the processes of diagnosis aircraft systems in operation; the research objective is improving the aircraft systems fault tolerance level by the development of new models, methods and information control and diagnosing technology of aircraft systems under input data uncertainty; novelty: for the first time developed a mathematical model of the rational solutions synthesis of the nonlinear diagnosing aircraft systems problem with multiple failures, which unlike existing identifies their technical condition using data interval analysis and monitoring of the system controlled parameters; improved methods of aircraft systems technical condition classification based on probabilistic neural networks, in which the Mahalanobis distance is applied to the activity, which improves the probability of single and multiple system failure detection; was further developed information technology to automate the process of decision support in the aircraft systems technical state diagnosis by using the established computer systems that can improve the efficiency and depth of diagnosis; the degree of implementation - implemented in the design of gas turbine engines ground control systems; scope of use - information technology.
