“…During operation by end users, vehicles can accumulate and send the necessary data to the manufacturer, providing two-way communications with the digital model the car. This allows the digital twin to be analyzed over the long life cycle of the product and improve the built-in quality of subsequent vehicle generations [23].…”

Problem of long timeframes of new car model development cycle due to excessive testing process of numerous vehicle prototypes is specified. Positive example of solving the problem using digital twin, computer modelling and virtual testing technologies in Formula 1 is given. Positive effect of virtual verification and validation during the development process on built-in product quality and development cycle time reduction is indicated. Existing project management V-models in automotive and information technology industries are reviewed and analyzed. State standards and methodologies of project management, lean manufacturing and digital twin development are reviewed. The improvements based on project life cycle, project management processes and product life cycle are enumerated and explained. Improved V-shaped project management model is described and visualized. The proposed model positive effects are described: it allows to increase the level of built-in vehicle quality, shorten its development cycle timeframes while providing the connection between project management and product development processes.

The article develops a mathematical model of the variable flow pump of the aircraft power supply, designed to simulate the operation of the power supply depending on the speed of the sustainer engine, oil temperature, pressure and supply (removable power). In addition, a control algorithm has been developed that provides the required quality of the transient process, which is achieved by installing additional hydraulic resistances between the servo piston cavity, the drain hydraulic line and the control spool, which change the flow characteristic of the pump and contribute to the fastest attenuation of the transient process and reduce its oscillation.

“…The unification of the format is also conducive to data storage and query. [76] proposed an approach to establish a single information environment by creating the multidimensional database in order to realise data standardisation. Eventually, processed data will transform into an analytic model as the input.…”

Digital twin (DT), primarily a virtual replica of any conceivable physical entity, is a highly transformative technology with profound implications. Whether it be a product development, design optimisation, performance improvement, or predictive maintenance, digital twins are changing the ways work is undertaken in various industries with multifarious business applications. Aerospace industry, including its manufacturing base, is one such keen adopter of digital twins with an unprecedented interest in their bespoke design, development, and implementation across wider operations and critical functions. This, however, comes with some misconceptions about the digital twin technology and lack of understanding with respect to its optimal implementation. For instance, equating digital twin to an intelligent model while ignoring the essential components of data acquisition and visualisation, misleads the creators into building digital shadow or digital models, instead of the actual digital twin. This paper unfolds such intricacies of digital twin technology for the aerospace community in particular and others in general so as to remove the fallacies that affect their effective realisation for safety-critical systems. It comprises a comprehensive survey of digital twins and their constituent elements. Elaborating their characteristic stateof-the-art composition along with corresponding limitations, three dimensions of the future digital twins for aerospace sector, termed as aero-Digital Twins (aero-DTs), are proposed as an outcome of this survey. These include the interactive, standardisation, and cognitive dimensions of digital twins, which if leveraged diligently could help the aero-DT research and development community quadruple the efficiency of existing and future aerospace systems as well as their associated processes.
