Abstract. The authors constructed a mathematical model for changing the parameters of an aircraft engine for use in the ECTM (Engine Condition Trend Monitoring) system, which will allow for the maintenance of foreign-made aircraft under sanction restrictions based on the airline data.

The mathematical model was constructed with the regression analysis method on the basis of statistical data of PT6A-114A engines technical operation over a five-year operation period. The proposed solution allows the values of the basic parameters of the PT6A-114A aircraft engine to be obtained, the operator having the opportunity to independently analyze the trends of changes in the engine condition without the ESTM system. The main advantage of the obtained research results is independence of the aircraft operator on foreign engine parameter assessment services. The airline can assess the engine parameters independently. One of the next stages of further implementation of the ECTM system within the airline is the development of software that will automate the process of reading the aircraft engine parameters, conduct their analysis and correlate to the engine operation and maintenance documentation and issue a plan of corrective actions on the engine and its components.

Keywords: aircraft engine, parameters, regression analysis, basic values, maintenance.

Abstract. The use of modern surveillance equipment in accordance with ICAO recommendations is aimed at improving the efficiency of air transportation, increasing the capacity of airspace and airfields, and improving the safety of flights and ground operations. The introduction in the Russian Federation of a multi-position surveillance system (MPSS) based on automatic dependent surveillance of the broadcast type (ADS-B) is intended to facilitate the implementation of state and regional aviation development programs in terms of creating conditions for improving flight safety, availability and quality of air navigation services for airspace users. Therefore, the analysis of the principles of constructing a working area and processing navigation information in a multi-position surveillance system for improving the accuracy of aircraft position-fixing is an urgent research task. An approach to improving the efficiency of the MPSS operation when processing information in conditions of noise and interference has been considered. Analysis of the results of modeling the proposed algorithm based on the discrete Kalman filter shows high accuracy of estimating the planned coordinates of an aircraft. Specialized software has been developed to automate the process of calculating and constructing working areas of a multi-position surveillance system.

Keywords: multi-position surveillance system, multilateration technology, automatic dependent surveillance, Kalman filter, working area, location, least squares method.

Abstract. In the International Civil Aviation Organization, an important area is the development of new approaches to constructing and maintaining effective aircraft flight paths. Developing a flight control system capable of not only stabilizing the position, but also accurately tracking the trajectory for an aircraft is a rather complex task. In this paper, an algorithm for generating trajectory tracking control is proposed based on the methods of optimal control theory (OCT) using optimal filtering theory (OFT) approaches to estimate the trajectory motion parameters. The formulation of an autonomous optimal control problem is considered. In the paper, the flight route maintenance quality indicator is formulated as minimizing the deviation of the actual flight path from the specified one. The expediency of implementing the proposed approach is confirmed by the methods of simulation statistical modeling. To test the validity of the proposed approach, a simulation modeling of a typical flight path tracking under expected operating conditions was performed. Analysis of the results obtained during the simulation modeling shows that the deviation of the controlled flight path parameters from the specified values does not exceed 5Β m. The results demonstrate the efficiency of the algorithm for tracking a specified flight path and its stability to external disturbances.

Keywords: aircraft, flight path, Kalman filter, optimal control, optimal filtering, global navigation satellite system, trajectory control system.

Abstract. The article considers the urgent task of optimizing the use of the existing and promising fleet of aircraft of domestic production within the framework of the creation of a single Far Eastern airline. The data on the assessment of the required number of aircraft of domestic production through a single consolidated order from all airlines of the Far Eastern region analyzed. It is shown that mathematical modeling and optimization methods play a significant role in the optimal design of the number and nomenclature of aircraft in the region, which are successfully used to select the best parameters and characteristics of aircraft or its subsystems at various stages of design, dividing the task into two interrelated models: parametric and operational. A systematic scientific and methodological approach to the external design of aircraft proposed, so it is possible to generate many design options for aircraft, limiting only those parameters that significantly affect the efficiency of the airline’s operation. The result of the study is the fulfillment of the task of optimizing the aircraft model range for subsequent operation in the conditions of the Far North, the Arctic, Siberia and the Far East. The analytical materials obtained allow us to compare the expansion plan of the route air transport network and the calendar plan for the production of aviation equipment for the united Far Eastern airline based on the produced relationship chart between airlines and aircraft manufacturers.

Keywords: mathematical modeling methods, unified Far Eastern airline, model range optimization, unified consolidated order.

Annotation. The article provides statistical data on passenger turnover of air transport in comparison with other types of transport in Russia, as well as flight safety indicators over the last decade. The leading types of events leading to aviation accidents have been identified. It has been revealed that the cause of many of the negative aviation events that have occurred are violations of the functional state, loss of performance and errors of crew members, which are facilitated by the conditions of the person’s environment.

The authors study the variability of heart rhythms, reflecting changes in the psycho-emotional state of a person during noise. The results of the study confirm that a change in the activity of the sympathetic and parasympathetic parts of the autonomic nervous system of the human operator. This indicates the development of stress under the influence of noise.

The authors demonstrate the importance of counteracting the negative effects of noise on aviation personnel to improve flight safety and reduce injuries and propose to use otoprotection with an oxygen-argon gas mixture to concentrate the attention of the crew in extreme situations.

Key words: air transport, aviation accidents, human factor, noise, otoprotection, argon.
