Parallel Piezoelectric Shunt Damping of Rotationally Periodic Structures

<div>Numbering of the 28 PZT patches and numbering of the blades along the circumference of the drum. The upper figure indicates the electrical connections of the PZT patches in 4 independent loops for the parallel shunt; the lower figure shows the shape of the targeted modes (1F7).</div>
