Evaluation of effect of size of wear particles (accumulated on filter element) on the intensity of their x-ray fluorescence when diagnosing the oil system of aviation GTE

UDC 621.452.3:53.082.56 BBK 39.55:22.345/.346

Stepuk T. D., Pavlinsky G. V.

The article gives the assessment of the aviation engine technical status based on intensity of the flush x-ray fluorescence from its filter element. The evaluation rests on dependence of x-ray fluorescence analytical signal on the size of metal particles in the flush. The number of the large particles characterizes the level of wear of the engine.

Key words: x-ray fluorescence; aviation engine technical status; flush from filter element; impact of the size of particles on intensity; wear processes.

Simulating of air transport systems with the aid of markov-process apparatus

UDC 004.588 BBK 74.5

Chokoj V. Z.

The article presents the author’s packet of tool skins for an ECM enabling to simulate technological processes in air transport systems during aircraft maintenance. The tool skins implement mathematical models as a base for different Markov processes.

The presented tools of mathematical modeling are supposed to be useful along with the educational process for operating organizations which are interested in the issues of optimization and management of technological processes.

Key words: mathematical model, air transport system, Markov processes, Markov sequences, Markov chains, reproduction and death processes, mean-value dynamics method.

Optimization tools for air transport waiting systems

UDC 004.588 BBK 74.5

Chokoj V. Z.

The author considers ECM tools enabling to solve the problems of optimizing the structure and operating modes of civil air transport systems. The tools are mathematically rested on the apparatus of the waiting theory. The tools functionality provides modeling the multi-channel and  separated,  opened and completed waiting systems, waiting systems without queues or with the various queuing disciplines, waiting systems with different sources and characteristics of service requests. 

The tools for multi-aspect modeling of waiting systems are supposed to find application not only in the educational process, but also in the real experience of civil air transport systems.  

Key words: air transport system, waiting theory, request flow, request servicing mode, waiting system
