Making the wings on passenger jets thinner and longer can go a long way toward reducing drag and making them more efficient, but they vibrate like crazy. Engineers at NASA and Boeing are now tackling ...

Flutter is an extremely significant academic topic in both aerodynamics and aircraft design. Since flutter can cause multiple types of phenomena including bifurcation, period doubling, and chaos, it ...

A recent version of the transonic truss-braced wing concept in a wind tunnel at NASA's Langley Research Center. They carried out testing between September and November, 2019. (Harlen Capen / NASA /) ...

Aircraft flutter is a kind of self-excited vibration, meaning an aircraft flying on the ground will start to flutter or vibrate when it is disturbed. But due to the existence of the damping, this ...

Engineers found a way to help airplanes avoid stall with lightweight plastic flaps that flutter with pressure changes. The flaps mimick a class of feathers that are key to birds' most daring aerial ...
