“…Then the distribution of the output power of the primary power supply source to ensure the operation of the autonomous drive control system (see Figure 8) is shown in the diagram (see Figure 9). From the Equations 3, 4 and Equation 8, we determine the power dissipated in the secondary power source, stabilizer, static power amplifier, and operating mechanism (Equations 13,14,15,16). Based on Equations 3, 4, 8 and performance of the energy channel (see Figure 3) through its output and dissipation power Equation 9, we determine the total power of Р 1 , of the elements, or through their coefficient of consumed by the energy channel of the autonomous drive control system (see Figure 8), and equal to the power of the primary power supply source, as Equation 17Let us estimate the coefficient of performance of the energy channel  ЭК 3 of the autonomous drive control system (see Figure 8) through its output and dissipation power of the elements, or through their coefficient of performance, as Equation 18.…”

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.
