| Title of the article | Determination of the forces acting on the plate moving at an angle of attack by the method of discrete vortices |
| Abstract. | Problem statement. It is required to determine the force acting on the plate when it flows around an incompressible air stream at various angles of attack. Results. Dependences of the coefficient of the normal force of the plate on time for different angles of attack by the method of discrete vortices are obtained. By varying the step of integrating the differential equations of detached vortices and splitting the plate, the convergence of the calculated force coefficients is ensured with the available experimental results. Conclusions. The significance of the results obtained for the construction industry consists in the possibility of evaluating the lamellar structural elements for strength and fatigue by applying the calculated coefficients of normal force. |
