Digital Twins in the Theory and Practices of Aircraft Electrical Power Systems

Abstract

The article addresses the problem of applying new digital technologies at the aircraft electrical equipment life cycle stages. The features pertinent to the development and application of digital twins in aircraft electrical equipment systems are presented. A unified approach to development of mathematical models for digital twins, called an energy processes mathematical prototyping method, is suggested. This method is based on taking into account the energy potentials and flows occurring inside the system, as well as incoming and outgoing energy flows. It is shown that for particular tasks arising at the products and systems life cycle stages, it is possible to use projections of the full model on the observed and controlled parameters corresponding to these tasks. Such projections are called "digital portraits". In addition, a set of properties of a particular object or system due to which it can perform informational interaction with other objects (systems), and which ones follow from the digital twin full model, is proposed to be called "digital passports".
