Long-span wings generate less drag, but design rules limit their slenderness to avoid the potentially catastrophic aeroelastic instability known as flutter. Now, as part of the search for fuel ...

Gulfstream’s G500 has completed flutter testing, the culmination of 50 hr. of testing. Three flight-test aircraft have flown more than 430 hr. in more than 105 flights. The flight-test program began ...

Boeing T-7A tail number 7002, the first to be delivered to the USAF, taking off from St Louis Lambert International Airport, Missouri, co-located with Boeing's factory. (Boeing/Eric Shindelbower) The ...

Flutter is a dynamic aeroelastic instability caused by interaction of unsteady aerodynamic forces with elastic vibration of the structure. At the so-called flutter critical velocity, the damping ratio ...
