It's shown the necessity to use functional coatings in engineering, which can be formed in many layers and contain a number of components what based on the analysis of literature data about ways to ensure the required resource of machine parts and mechanisms. Existing technologies and the corresponding equipment require the prefabricating of the alloys which the coatings are formed. This significantly limits the control of the coatings' composition. It's shown the advantage of ion-plasma technologies developed at National Aerospace University "Kharkiv Aviation Institute" over the existing technologies. In particular, due to the spraying of a large number of cathodes-targets, these technologies allow the formation of multicomponent coatings of almost any composition. When implementing ion-plasma technology for the formation of coatings, a decisive role plays the generator of the flow of particles of the coating material. It has been proposed to supply voltage to each generator element through a chain of resistors, the total resistance of which is regulated by the control system of the corresponding program to improve the power supply system of such a generator. Such an approach to the improvement of the power supply system of the technological generator of the coating material is implemented in the developed laboratory experimental-industrial process plant for the formation of a model coating of tungsten carbide. It was considered two possible schemes for creating resistive chains with regulated resistance. It was selected the scheme, which consists of a smaller number of elements. The important role of any resistive chain in the operation of the technological generator control system has been determined. It was proposed the optimal choice of the nominal values of the resistors included in the chain. The optimal choice of the nominal values of the resistors included in the chain has been proposed. The conducted analysis of experimental data carried out by the authors suggests that each such chain should have individual features, in particular, the boundaries and the step of resistance, the maximum power of heat losses. These and other parameters are usually determined experimentally.

This article discusses the possibility of using a multicopter type aircraft as a transport vehicle in urban environments. This type of transport is the most promising in the near future, given the constantly growing number of traffic jams in large cities. The assessment of this aircraft is presented, taking into account the reliability requirements specified in the regulatory documents. The analysis of the aviation regulations requirements in terms of the aircraft systems reliability was carried out. Also the paper presents six options for the multicopter layout with a different number of propellers, taking into account the propeller control system, power supply system and control system. Other onboard systems are not considered, since their failures do not lead to an aircraft crash. An assessment of these options, taking into account the multicopter most critical onboard equipment layout according to reliability criterion by budgeting the requirements for one thrust generation channel, is given. Fault trees and failure situations that lead to a disastrous situation are also presented for each multicopter layout separately, as well as proposals for the number of independent channels for the power supply system and control system. Based on the set quantitative requirements for the occurrence of a catastrophic situation for the main on-board equipment and various layout options, taking into account the number of propellers and proposals for their architecture, power supply systems and control systems the most promising multicopter architecture options are determined. They meet the requirements for failure safety for a catastrophic situation.

In the paper, the PV power supply control system is proposed to realize the uninterrupted power supply, including DC and AC supply. By the method of combining software with hardware, through the solar panel to the configured two pieces of battery could realize the function of fast and slow charging, and the supply battery is changed by testing the battery power to the load uninterrupted power supply. Moreover, when the output voltage of the solar panel is lower than the battery, the output voltage of solar panel is boosted by DC/DC circuit to make the solar panel at low pressures also to charge the battery, effectively solving the difficult solar energy in the weak power supply problem.

The natural gas industry, as well as other industrial activities, is not free from accidents, which can cause serious consequences to the integrity of people and properties. For this reason, it is necessary to develop studies to determine what are the possible causes of LNG leakage during the loading or unloading operation. This paper aims to determine the reliability of the Cargo control system electric power supply system applying Markov Chain technique. This reliability modeling tool is used because the system consists of several components in passive parallel. Based on the reliability analysis maintenance recommendations are proposed aiming at reducing system failure probability. The method used in this paper is divided in three steps. The first step consists in carrying out a study to identify what are the components that are part of electric power supply system. The second step involves the reliability analysis of the electric energy supply system. Finally some maintenance recommendations are presented aiming at reducing system failure rate. This analysis is used for the analysis of a LNG carrier operating in a Brazilian harbor indicating the most probability failure modes of this system and the most suitable maintenance actions to avoid them.
