Autooscillations of a Multlink Aerodynamic Pendulum

A multilink pendulum located in a flow is considered. On the last link of the pendulum, a wing is installed, on which the interaction with the flow is concentrated. The dynamics of this system are studied as a potential working element of an oscillatory wind power plant. For different flow velocities, periodic modes are numerically investigated that occur under different numbers of links and different values of the external load. It is shown that the maximum power that can be obtained with a two-link pendulum is greater in a wide range of flow velocities than with pendulums with more than two links. At the same time, pendulums with a large number of links make it possible to obtain considerable power in a wider range of load values than a two-link one.
