European researchers have used scaled aircraft demonstrators to test new concepts for lighter, larger-span wings intended to avert flutter problems. The ground vibration tests were conducted at a ...

Japanese tits have previously been observed combining different calls into phrases to convey meanings. The birds may also use their wings to signal to their partner that they should enter the nest ...

Russian analysts are conducting tests with an Irkut MC-21-300 model with wings representative of those created with domestically-sourced composites. The research at the Central Aerohydrodynamic ...

NASA has actively suppressed flutter of a flexible wing in flight, potentially paving the way for lighter, lower-drag wings on future fuel-efficient aircraft. The feat was demonstrated on flights of ...

Long, narrow wings are intended to reduce fuel consumption and increase comfort in aircraft. However, wing flutter must be eliminated for this to happen. The US space agency NASA and the aircraft ...
