The article conducted a modeling number of the working process in the flame tube of the main chamber of combustion of the turbojet engine of tactical aviation aircraft. The geometric model of the flame tube has been created and adapted for carrying out the interconnecting calculation of heat and stress-strain stations of the walls of the flame tube under the influence of operating factors at the numerical modeling of the working process. Quantitative-qualitative analysis of modeling results was carried out and the connection between peculiarities of working process flow and characteristic damage of the flame tubes discovered in operation was established. The possibility of using modern CAD/CAE systems to solve scientific tasks to ensure maximum use of resource opportunities of the main and especially responsible parts of turbojet engune on the basis of the assessment of their damage. The obtained results of work process numerical calculations, thermal state and VAT of the heat pipes walls of the main combustion chamber refuse: identify critical areas and perform optimal construction; the decision to establish or extend the heat pipes resource is substantiated based on the assessment of the degree of depletion of harmfulness in conditions where the developer and manufacturer do not fulfill their obligations in terms of author support; to provide recommendations to aircraft repair companies regarding the finalization of aircraft structures during the implementation of the overhaul, avoiding long-term experiments to determine their ultimate state.

The armed aggression of the russian federation showed that the number of military formations does not give advantages on the battlefield. Thanks to skillful leadership and modern weapons, which include guided air bomb, it is possible to gain an advantage on a specific section of the front. Recently, the modern world trends are to increase the accuracy of ammunition damage. The effectiveness of guided air bomb damage in comparison with conventional air bombs is beyond doubt. The method of forming regions of permitted dropping conditions of guided aerial bombs of modular design is a procedure for finding sets of vertices of the area of permitted dropping conditions. Its essence consists in selecting a subset of points with extreme properties from a set of some points in the space of phase states of the bomb. This procedure is iterative, convenient to implement, and the use of well-researched methods of linear programming allows to ensure computational stability of the procedure in the entire range of possible conditions of combat use of bombs. The problem of optimal control is reduced to a boundary value problem – to find a solution to a system of equations whose phase coordinates satisfy the initial conditions and boundary conditions. In addition, according to the principle of the maximum, the Hamiltons function under optimal control should reach a maximum. Based on the results of research, it was established, that: function H reaches its maximum at the obtained control values; from the position obtained as a result of the solution of the minimax filtering algorithm with correction from the satellite navigation system, the hypothetical problem of optimal launch of the guided air bomb in the final control area is solved; a transition to a new position is made with the control obtained by solving the problem of optimal launch into the final control area; in the new position, the parameters of the guided air bomb own movement are monitored and filtered; the solution of the problem continues until the end of control of the guided air bomb.

A conceptual approach to predicting of aircraft no-failure indicators during operational use is proposed. This approach is based on the use of methods of statistical analysis of operational data for a certain period of time. The results of predicting the failure flow parameter using a combined model of acceptable level and their standard deviation are presented. The results of predicting can be used to control the reliability (no-failure operation) of aircraft equipment in order to make grounded decisions about the continued operation of their equipment beyond the established life service. In order to create highly reliable aircraft it is necessary to predict failure rates, which involves the establishment of their range and quantitative values. To predict the thresholds of failure of the aircraft, it is advisable to use the following interval indicators of reliability: Ricao “accident level” indicator, which takes into account the number of flight failures detected in 100 hours and actually determines the dynamics of changes in the level of flight safety; “failure flow parameter, ω (t)”, which takes into account the total number of failures per hour of flight and determines the dynamics of changes in the level of operational The predicted value of the indicator of the “reliability upper control limit”, which determines the limit level of operatioanl reliability, at which further reliable operation of the aircraft is not desirable. According to the concept of “acceptable level of safety performance”, predictions of indicators for three levels of flight safety (acceptable, target, critical) are calculated, which need to be monitored in future periods of aircraft operation and make certain management decisions according to the proposed algorithm. The results of calculation for prediction indicators of reliability for specific types of aircraft according to their operation in the period 2017-2019 are presented.

The materials of the article present a method of improving the control of the technical condition of automobile and armored vehicles by automating the accounting of the cost of its engine resources. The article reveals the essence, content and main stages of the above methodology, as well as prospects for its implementation in the operational and service activities of units and bodies of state border protection. The methodology is developed on the basis of existing methods and methods of obtaining information tested by leading scientists in this field and the procedure for maintaining technical documentation in units and bodies of the State Border Guard Service of Ukraine, which is regulated by regulations. The essence of the methodology is to create a single information space and database of samples of armored vehicles and phased data on their registration and movement, during the main modes of technical operation, as well as continuous monitoring and control of their technical condition, resource consumption, competence drivers and repairmen, the correctness of technical documentation. In the development of this technique used scientific and methodological tool for automated submission of information about the equipment and its personnel. The method is designed for use by specialists of engineering and technical units of state border guards and regional departments, as well as specialists of the Department of Armaments and Technical Support of the Department of Logistics of the State Border Guard Service of Ukraine. The scientific novelty of the advanced technique is that, in contrast to the existing ones, it uses information technology of automated accumulation of information about a sample of armored vehicles when registering and evolution during operation, creating a single information space and increasing the speed of phased automated feeding. information that will positively affect the safe state of the operational process as a whole.
