METHODOLOGY FOR ANALYZING THE FAULT SAFETY OF SYSTEMS AND AGGREGATES OF A MULTI-AGENT GROUP OF AIRCRAFT

Abstract

Areas of application of CALS technologies are considered to be: improvement of activities
in the field of heterogeneous processes occurring at all stages of the life cycle (LC) of products;
supply chain management throughout the entire LC of products (from the creation of the product
concept to its disposal); electronic integration of organizations (enterprises) involved in these
processes at various stages of LC; management of support for LC products One of the most relevant
areas of development in the aviation industry are: multi-agent technologies for improving the
efficiency of aircraft (aircraft of various types in a group and a single mission) and CALS technologies.
The article proposes a methodology for analyzing the fault safety of systems and aggregates
of the multi-agent group of aircraft as a whole, by types of aircraft, their systems, and aggregates.
The methodology is given on the example of statistical data of AP and PAP 16 systems: flight navigation,
exhaust, ignition, fuel, control, power supply, air conditioning; hydraulic, radio communication
equipment, control devices, and aggregates: engine, propellers, wings, windows, lantern,
ten aircraft AN-2, L-410, Yak-40, An-24, Tu-134, Yak-42, Tu-154, IL-62, IL-62M, IL-86. In the
proposed methodology for analyzing statistical data of AP and PAP, transformations with matrices
are used, which allow not to be limited to the number of systems, aggregates, and the aircraft
themselves. The operating time before the functional failure of systems and aggregates by types of
aircraft was calculated, the average probability of functional failure of each of the systems and
aggregates in a multi-agent group was determined, and the time before the functional failure of a
multi-agent group of 10 aircraft as a whole, which was 132.5 hours, and it was determined that
PAP and AP are more likely to occur with the chassis and engine of the aircraft. The given methodology
allows: to correlate quantitative reliability requirements for systems and aggregates,
taking into account random factors and uncertainty factors; to assess the feasibility of the established
reliability requirements; to conduct a comparative analysis and justification of the choice of
a rational variant of the composition of the aircraft group.
