A review of scientific and technical research in the field of aviation to achieve the goals of ACARE and Flightpath 2050 is provided. It is emphasized that today’s environmental protection in conditions of a large number of impact factors is and will continue to be a key driver in the development of aviation industry as a whole. Achieving the adopted development programs can be realized only with a comprehensive improvement of the airframe and power plant, including on the basis of research into new breakthrough design and schematic solutions. They include the physical principles of power plant operation, in particular, the new scheme of hybrid turbo-electric power plant (HTEPP). An overview and analysis of integration properties of the aircraft with HTEPP were carried out. The introduction of hybrid-electric technology expands significantly the design space of modern aircraft. The full potential of electric technologies will be used through the synergistic and systemic integration of subsystems of the regional aircraft. Ways of development of electrical technologies at enterprises in Ukraine are shown.
