The article deals with the features of construction of combined airborne power supply of aircraft with the use of renewable energy sources. It has been established that the introduction of renewable energy sources into airborne electrical supply systems of aircraft takes place, however, the issue of their introduction into the structure of the primary and emergency power supply of airborne aircraft complexes remains promising and topical. Thus, due to the complex specific operating conditions, it is necessary to monitor the state of aircraft battery-operated batteries, the authors propose to implement monitoring of the status online of on-board batteries in the block, which will also perform the functions of the charger. From the onboard generators, all the electronics are powered on board aircraft, so if the generators stop working, then all the onboard equipment of the electric system of the aircraft will be blown away. In this case, in some types of aircraft, manufacturers install retractable wind power plants. In the meantime, solar cells are another of the most persistent alternative sources of electric energy in aircraft. Thus, according to the recommended variant of the system of power supply of aircraft, the unit of storage batteries has a capacity sufficient to supply in an emergency during the flight not only responsible consumers (control and navigation), but also the power supply of electromechanical complexes of the power system of electric motors. Proceeding from the fact that the modern concept of the development of aircraft put forward the requirements related to the miniaturization of onboard systems of energy and electronics, as well as requirements for the use of advanced technologies for the manufacture of aircraft design, the implementation is also relevant, if possible, (depending on the design aircraft) as an additional source of the main on-board power supply system for solar panels at level with retractable wind power plants. The article presents the version recommended by the authors of the system of airborne electrical supply of the aircraft using renewable energy sources. The authors propose the introduction of additional power sources into the structure of the main power supply system on the basis of renewable energy sources and additional, electric motors, installed in parallel with aircraft engines, with the purpose of safety-free landing of the aircraft, in the event of failure of aircraft engines and extension of its flight time.
