Аннотация:The model of a wind-powered vehicle is proposed. The mechanism uses the wing to transform the energy of the upcoming wind flow into the energy of the mechanical motion in such a way that the vehicle goes against the wind. The new type of a wind-receiving element is introduced that is based on the principle of a slider-crank mechanism. The corresponding dynamical model is constructed. Asymptotic methods are applied for the parametrical analysis of the dynamical system. The existence of attracting steady regime is shown. Results of the parametrical analysis were used for construction of a prototype of such a vehicle. Experiments with this prototype proved qualitative predictions of the mathematical model.
