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.

In a one-dimensional approximation and in the absence of friction forces, a mathematical model has been developed for the steady flow of an incompressible fluid along a straight line, for example, a drainage gutter, into which a distributed flow flows from above. The boundary condition missing for solving the system of equations of momentum and continuity is determined using the principle of minimum potential energy. For a rectangular chute, equations are obtained that allow one to calculate the distributions of the layer thickness and fluid velocity along the length of the chute with a plug at one end and without a plug, slope and without slope to the horizon, depending on the intensity of the incoming flow, the size of the chute, and the density of the liquid. This model, by means of a simple recalculation, can also be extended to the flow in a trough of a different cross-sectional profile. The results of the study can be applied to the calculation of external drainage systems.

Investigation of the feasibility of using wing struts and non-retractable landing gear struts on a light multi-purpose aircraft

In this paper, we consider a method for determining the feasibility of using a wing strut and non-retractable landing gear on a light multi-purpose aircraft. In a certain range of cruising speeds and flight ranges, it is advisable to use non-retractable landing gear and wing strut. With an increase in cruising speed and flight range, these engineering solutions must be abandoned to improve aerodynamic characteristics. The dependencies obtained in this work make it possible to make decisions on the use of a wing strut and non-retractable landing gear at the early design stages. To obtain aerodynamic characteristics in the Siemens NX program, a three-dimensional model of a light multi-purpose aircraft was created and an aerodynamic experiment was performed in the FloEFD program. Then the calculation of flight performance was carried out. As a result of the study, the dependence of the speed up to which it is advisable to use the undercarriage strut and fixed landing gear on the flight range for a light multi-purpose aircraft weighing 2000 kg was obtained. When designing an aircraft, it is necessary to make decisions about the use of one or another engineering solution, which, on the one hand, has a positive effect on aerodynamics and negatively on the weight of the aircraft, and vice versa. In this article, using the example of a wing strut and fixed landing gear in the first version of the aircraft, and a cantilever wing and retractable landing gear in the second version, a model for solving such a problem is shown.
