When the Darrieus rotor rotates, a force is generated that is akin to the Magnus force: perpendicular to the oncoming flow velocity. In this study, it is calculated based on a quasi-static model of the aerodynamic action and compared with a similar f

We consider a small device for converting the medium’s flow energy, which is designed based on the use of a crank mechanism. A blade interacting with the flow is fixed on the connecting rod of the mechanism and the crank shaft is connected to the e

An autonomous mechanical system with two rotational degrees of freedom, undergoing the action of conservative and nonconservative forces, is considered. The corresponding dynamical system contains changeable parameters that can be treated as amplifyi

We model movements of a person swinging on a swing. We consider a flat three-link hinged mechanism as the main mechanical model of the person sitting on the swing. The first, second, and third links model the human body, two hips that are rigidly con

A closed mathematical model of a double Magnus type wind turbine with a horizontal axis is constructed. The propellers of the turbine are supposed to rotate in opposite directions. For such a system, equations of motion are derived. In the case of di

We consider a mathematical model of a horizontal-axis wind-energy unit in which Savonius rotors are used instead of classical blades. The Magnus force formed due to the autorotation of Savonius rotors creates a momentum supporting the rotation of the

We consider a controlled mechanical system with one degree of freedom described by an angular coordinate. The system is under the action of conservative and nonconservative forces. It is assumed that a corresponding dynamic system has a variable para
