The occurrence of flutter as a hazardous event of elastic structures in flow environment mostly leads to failure and demolition of the aircraft. The loss of flutter stability within a flight envelope ...

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 ...

Wings with longer spans and lower weight generate less drag – and are therefore more energy efficient. More efficient lift could reduce kerosene consumption and thus reduce emissions and costs. The ...

As Boeing’s 787 illustrates, airliner wings are more slender than they used to be. But as wings get slimmer in pursuit of lower drag and lighter weight, flutter becomes a greater concern. Flutter is ...

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 ...

IN 1928 a monograph on the “Flutter of Aeroplane Wings”, by Messrs. R. A. Frazer and W. J. Duncan, was produced at the National Physical Laboratory, summarising in a single useful volume the work that ...
