“…It is also confirmed by the results of the PISA international research. For example, Kyrgyzstan refused from the participation in the 2012 and 2015 PISA research, supporting its position with the fact that the planned reform stages had not been implemented, while the factors affecting the results continue having an adverse effect on the quality of school education (Gridina and Andreev, 2017).…”

The relevance of the research issue is caused by the transition to the 12-year educational period at school and insufficient elaboration of the theoretical and scientific-methodical support of the preparation of future teachers to the implementation of new pedagogical approaches in the conditions of renewed standards of general education. So, the objective of the paper is to develop the structure-conceptual model for preparation of future teachers to the implementation of new pedagogical approaches in the conditions of renewed contents of the general secondary education in the aspect of the system-activity approach providing an opportunity to consider the ways the future teachers may independently design their cognitive capacities by their own actions in the process of practice. The leading research method is modeling that allows designing the process of preparation of future teachers to the implementation of new pedagogical approaches in the 12-year school period based on analysis, synthesis, surveys, observations, experiment, processing of the results with the methods of mathematical statistics. The paper presents the structure-conceptual model for the preparation of future teachers to the implementation of new pedagogical approaches in the conditions of renewed contents of school education, reflecting the stages, contents, targets, tasks and expected results of the experiment, as well as the value-based motivation, contents and process components, criteria and possible levels. The implementation of the model implies the professional testing of future teachers in the professional activities in the conditions of renewed standards of general education at school and is focused on testing of the scientific-methodical support and the support of their preparation process to the implementation of new pedagogical approaches. The materials of the paper imply the practical significance for the university teachers of the pedagogical specializations.

“…This approach to the analysis and synthesis of servo drives leads to the fact that when designing them, the real characteristics of the power supply source are not taken into account. Therefore the volume and mass of the equipment of energy sources can be overestimated (Andreev and Gridina, 2017).…”

“…The problems of increasing energy intensity, the stability of the output parameters of the power supply source, associated with a decrease in its mass and decrease in volume, are one of the main tasks of designing prospective autonomous objects, largely determining the possibility of creating a new type of guided product (Gridina and Andreev, 2017).…”

Intensive development of equipment contributes to a significant impact on the high level of competitiveness of new samples, improving technologies, and promise of enshrined ideas as well as resource intensity and time of their implementation. The relevance of the scientific paper lies in the fact that in the process of designing drive systems for guiding aviation equipment, one of the important elements is taking into account the limitations on the power source energy storage. The purpose of the scientific paper is to develop a mathematical model of energy efficiency of mechatronic modules and power sources for prospective mobile objects. An integrated approach is used to study the influence of structures and elements of storage devices on the characteristics of power sources in the interest of finding the ways to increase the energy efficiency of the entire drive system for guiding mechatronic modules of aviation systems in general. It has been determined that in order to reduce the weight-size parameters of the power supply source, the stabilizer in the power section, as a rule, is not set. It has been found out that power and information sections of drive systems differ from each other in terms of the stability of the energy coordinates. And stabilized parameters (potential, current) are necessary only for the information channel. With the help of analytical dependencies, the main parameters of the primary source were evaluated depending on the efficiency of the consumer, efficiency of the stabilizer and efficiency of the secondary power source. A method to study the influence of elements of the energy (power) channel on the output power of the power source the mechatronic modules for prospective aviation mobile objects (autonomous aviation drives, guided missiles, guided parachute systems) is being developed.

“…For anisotropic thermal conductivity, it is possible to specify the works of authors (Formalev and Kolesnik, 2007;Formalev et al, 2009 Gidaspov et al, 2018). The mathematical modeling of the complex problem, namely, the anisotropic thermal conductivity, filtration, injection, formation of a protective liquid film with downstream flow and evaporation is carried out for the first time (Gridina and Andreev, 2017).…”

A closed mathematical model of heat and mass transfer under the non-isothermal filtration through the organized pores of coolants with a strong dependence of dynamic viscosity on temperature with further injection into a viscous gas-dynamic flotation with the formation of liquid film and evaporation under the influence of aerodynamic heat flows has been developed. The aim of the paper is to develop the physical and mathematical basis of thermal protection with the automatic supply of coolant having a strong dependence of dynamic viscosity on temperature (by 3–5 orders of magnitude when the temperature changes by 200–2500°C). Such thermal protection system allows for operating without the mass removal that preserves the geometry of the structural elements at the intensive heating, which is very relevant. To achieve this goal, a mathematical model of the automatic coolant supply with filtration through the organized pores, injection into a high-temperature gasdynamic boundary layer with the formation of the protective liquid film and evaporation is formulated. The results with respect to the mass flow rate of the coolant, the mass evaporation rate of the formed liquid film and the temperatures of the structure which in all cases remain below the evaporation temperature of the cooler have been obtained.
