Analysis of Ways to Increase the Technical Indicators of the Energy Installation of the Drive Unit Circuit of AIrport Multipurpose AIr Conditioner Amk-24/56-131

The article analyzes the operational features of the power unit block (PUB) as an energy component of the AMK-24/56-131 airport multi-purpose air conditioner (AMAC) under the conditions of airport-technical flight support during prolonged continuous operation. It examines the statistics of typical AMAC failures and malfunctions that reduce its operational reliability and proposes alternative solutions for their elimination. The study explores ways to improve the PUB’s operational parameters to ensure the AMAC’s failure-free performance. The objective of this work is to enhance and increase the reliability and operational efficiency of the airport multi-purpose air conditioner.Research methods used: data collection, systematization, and analysis; mathematical analysis and numerical integration; theory and design of automotive and special equipment; reliability theory; fundamentals of production, operation, and repair of airport-technical flight support equipment; expert assessments; and comprehensive comparison of technical and technical-economic indicators. The analysis of ways to improve the operational performance and reliability of the AMK-24/56-131 AMAC’s power unit indicates that 70% of AMAC failures are caused by the PUB engine. As a result, the AMAC’s readiness factor is 0.40, its probability of failure-free operation is 0.79, and its mean time between failures (MTBF) is 108 operating hours. The most feasible solution is replacing the outdated Russian-made ZMZ gasoline engine with a modern, reliable, and fuel-efficient Mercedes-Benz OM364 diesel engine.By increasing the probability of failure-free operation of the power unit with the new Mercedes-Benz OM364 engine to 0.95, the overall probability of failure-free operation of the AMAC would rise to 0.8, significantly improving the readiness factor, operational reliability, and MTBF. The advantages of this approach include relative simplicity of implementation and lower costs compared to designing a new PUB for the AMAC. The material from this article will be used for further research on AMACs and their potential modernization. The findings are applicable in airport-technical and logistical support for the Air Force of the Armed Forces of Ukraine, automotive repair enterprises of the Ministry of Defense of Ukraine, research and military educational institutions of the Armed Forces of Ukraine.
