On dynamics of double pendulum in airflow
Dynamics of two-section aerodynamic pendulum is studied. It is assumed that the flow acts upon only one section of the pendulum. Aerodynamic load is supposed to be quasi-steady. All equilibrium positions are found, and their stability is analyzed. Numerical simulation is performed. Parameter ranges are found where periodical motions exist, as well as ranges where non-regular motions exist. Obtained results are in qualitative agreement with experimental data.
