Abstract

The concept of digital production represents the basis for the development of a digital production system, i.e. a digital factory. The digital factory represents the integration of the virtual and real factory. Inside the virtual factory, products, processes and resources are modeled on the basis of real data, which are then tested, improved and optimized through the application of digital production tools. Finally, when the results of the virtual factory are verified and all possible irregularities are removed, they can be applied in the real factory.

The primary goal of this paper is to present the process of designing a new product. The design process is an integral part of the modern digital factory concept. The concept requires full integration of product data, as well as systems for design, planning and production, including the design of technological processes.

The aim of this paper is to solve the problem of the budget coefficient of aerodynamic drag force of axisymmetric aircraft without wings. The problem is interesting because it provides a simple calculation of the axial aerodynamic coefficient of drag force for different airspeed. Ruling allows for easier comparison of the components of aerodynamic force coefficient of drag when changing airspeed and experimental values ​​from wind tunnel. The dependences of aerodynamic coefficients of aerodynamic parameters and shape aerodynamic configuration.The application of the proposed solutions will accelerate the flow of information theoretical researches aerodynamics of the aircraft. The accuracy in determining the values ​​of aerodynamic coefficients is one of the key factors for the assessment of flight "rapidly rotating" axisymmetric bodyes.
