Today's video features the Boeing 787 and the flutter test they carry out on this aircraft in July this year. Learn more about this new addition to Boeing stable here.

The Boeing 787 Dreamliner is a long range, mid-sized, wide-body, twin-engine jet airliner developed by Boeing Commercial Airplanes. It seats 210 to 330 passengers, depending on variant. Boeing states that it is the company's most fuel-efficient airliner and the world's first major airliner to use composite materials for most of its construction. Its development has involved a large-scale collaboration with numerous suppliers. [Source Boeing]

What's is flutter?

Flutter is a vibration that results from the changes in pressure distribution over the surface as its angle of attack is altered. If part of the airframe structure starts to vibrate - control surfaces particaly susceptible to this - then these oscillations can quickly reach structurally damaging proportions. To avoid this flutter, the designer may need to alter the mass distribution of the surface.
