Digital development of the global economy has increasingly severe implications for business, society and State. The so-called digital transformation (DX) has already turned from a scientific paradigm to reality, adjusting the development strategies of entire states, changing the face of social infrastructure and reformatting business processes. The market participants now face serious challenges: how to build their own business model and how to find their place in the digital ecosystem of the nearest future, drawing on digital technologies. That is precisely why the research and approbation of approaches to building an information model of a digital corporation are not only topical, but also very timely. The article provides an overview of several important studies in the field of DX, along with a comparative analysis of classical and digital models of corporate governance; it also shows the potential for the development of the CPM concept (Corporate performance management) considering the DX requirements and the advantages of the evolutionary planning approach. The authors present the paradigm of building information and analytical systems for digital corporation management with the use of advanced business intelligence based on dynamic intellectual models. The article describes examples of real projects on the development of support systems for decision-making in terms of marketing and financial management, including business effects from the use of similar systems.

This paper aims to provide an insight into the foundations of the development of the institution of venture capital financing, as well as summarize and conceptualize the experience of more economically developed countries, where the more favorable conditions have been created for the conduct of venture capital business. The authors' summarization of theoretical, methodological, and empirical data has made it possible to formulate the major issues characteristic of the making of the venture capital sector in countries with a transitive economy (Russia, in particular), as well as propose a set of solutions aimed at optimizing the legal and institutional space in the venture capital sector with a view to boosting the innovation activity of businesses. The authors derive the following major inferences: Venture capital financing is a modern institution whose activity is aimed at accumulating and redistributing temporarily available investment resources that are sought after in the sphere of innovation entrepreneurship; Countries whose economy may currently be recognized as transitive are characterized by a set of uniform issues: underdeveloped infrastructure in the national innovation system; lack of sources of venture capital financing; businesses reporting decreased innovation activity levels due to lack of economic incentives; lack of personnel resources; The evidence from the experience of more economically developed countries suggests that to enable the proper making of the institution of venture capital financing in countries with a transitive economy a set of interrelated objectives may need to be undertaken, namely: ensuring legal optimization; boosting investment attractiveness; altering the nature of partnership between the state, business, and science-and-education sector; reducing state participation in economic and research activity.

The development of electric aircraft, the design of which will use, apart from doing away with pneumatic and hydraulic transmissions, electric propulsion, is one of promising lines in aviation technology. As an example, the project of the X-57 Maxwell electric aircraft developed by NASA, which is equipped with 14 propulsion electric motors, is given. In view of insufficient energy efficiency of existing storage batteries, a combined storage battery-and-generator power supply system for electric aircraft is considered. In the considered system, the aircraft propulsion is provided by electric motors, which are powered by storage batteries in combination with permanent magnet generators. The generator shaft is rotated by an auxiliary internal combustion engine, which operates in an economical mode. The power circuit of an active rectifier producing the +270 V DC bipolar output voltage is proposed, with which the permanent magnet generator operates with a sinusoidal phase current waveform and a close-to-unity power factor. The active rectifier control system uses an enhanced phase-locked loop, which eliminates the need to use generator rotor position sensors. For determining the stability domains and revealing undesirable hidden attractors in the considered storage battery-and-generator power supply system, it is proposed to use special analytical-numerical computation procedures based on modifications of Lyapunov's functions methods. The article will be of interest for developers of both aircraft and ground-based self-contained electric power supply systems with a bipolar 270 V DC voltage that must meet stringent requirements for improvement of their mass-and-dimensions and power performance characteristics.
