Shaker vibrates the unique aircraft
The DLR researchers made the Solar Impulse prototype vibrate in various places using electrodynamic exciters known as shakers; these generate vibrations via a coil in a magnetic field, as with loudspeakers. Here, however, the magnetic force is not used to move a loudspeaker cone; instead, it is used to vibrate the aircraft structure directly.
