Building a visual mathematical model of the electromechanical wind power system with aerodynamic multiplication. In the process of constructing a visual mathematical model of the electromechanical system of wind turbines with aerodynamic multiplication, a mathematical apparatus for describing the system in local mean values of variables was used. Verification of the mathematical model was carried out in the MATLAB Simulink program. A visual mathematical model of the electromechanical system of wind turbines with aerodynamic multiplication is developed, which includes mechanical power losses on

Abstract:
In this article, we have considered the state of development of high-power horizontal wind turbines. The most common wind turbines for operation with variable wind flow speed usually include a frequency converter to ensure the compatibility of generator with network. It leads to decrease in the efficiency of wind energy conversion system, while the use of direct connection of the generator to the axis of wind wheel leads to a significant increase in the weight and cost of the generator. The wind turbine with aerodynamic multiplication is an alternative to such systems. Its prototype with 750 k

Abstract:
Energy transition is impossible without wind power development. The need for a mechanical multiplier to match the speeds of a wind turbine and generator leads to deterioration of the tech-nical system's indicators. Refusal of a mechanical multiplier is possible with the help of aerody-namic multiplication. Despite the presence of work in this direction, there is still no coverage of the influence of aerodynamic multiplication parameters on the choice of a generator. Main objectives of the study – analyze the requirements that a generator makes to wind turbine’s aero-dynamic multiplication para

Abstract:
The article analyzes the methods of increasing the efficiency of converting wind energy into electricity in wind power plants. It is noted that there are both aero-mechanical and electrical methods of increasing the efficiency of converting wind energy into electricity. Multiplierless schemes that allow to increase the efficiency of aero-mechanical conversion of wind energy are considered. These include the use of low-speed generators and aerodynamic multiplication. Aerodynamic multiplication is considered promising and more acceptable for high-power autonomous wind power plants, considering t

Abstract:
This paper is a contribution to analyzing the aerodynamic forces on a streamlined box girder (SBG) with coupled vibration in a potential flow. The key enabling step was to assume that the normal velocity of the airflow at an arbitrary point on the surface of the SBG was equal to the normal velocity of the surface motion. The aerodynamic drag force, lift force, and pitching moment were expressed as functions of the motion state of the SBG and the SBG’s shape-related parameters. To investigate the applicability of this force model, the analytical solution at various angles of attack was compared

In the context of energy scarcity caused by the destruction of energy infrastructure, instability of electricity supply and growing demand for autonomous energy sources, there is a need to develop independent and efficient energy supply systems. Of particular importance are wind power plants that are able to function independently, ensuring the stability of power supply even in crisis conditions. In this regard, it is important to investigate promising solutions that meet modern quality standards and can integrate into autonomous energy systems.

Abstract The motivation to accurately model the dynamics of flexible aircraft grew with the development of energy-efficient aircraft, consequently, great aspect ratio aircraft. The development of an accurate model that represents the flight dynamics of a flexible aircraft has been pursued by industry and aeronautical research organizations during the last decades. One of these approaches is to find a flexible aircraft model using systems identification methods.

Abstract The design of bladed disks involves both fluid dynamic and structural calculations through numerical methods that involve the discretization of the domains. On the fluid side, computational fluid dynamics (CFD) software is used while on the structural side, models are formulated by the finite element (FE) method and are reduced using different model reduction techniques. The fluid and the structural model are coupled as the aerodynamic pressure induces a load on the blades, while the blade deformation changes the boundary conditions for the flow field.

Abstract:
The solution to the problem on building mathematical models of technical objects through the approximation of various experimental dependences is offered in the paper. This approach is especially true for modeling aircraft because the aerodynamic coefficients of their models can be obtained either by full-scale study or by computer simulation only. Currently, the experimental simulation is performed either through the regression analysis (RGA) methods, or through spline approximation. However, the RGA has a significant disadvantage, namely a poor approximability of piecewise and multiextremal
