www.guardian.co.uk/international/story/0,3604,1574553,00.html The Guardian Aeroplane wings work better if they hum gently, according to aircraft eng ineer Ian Salmon of the University of New South Wales in Sydney, who fou nd that pumping sound waves over a plane's wings made air flow across th em more efficiently, producing up to 22% more lift. Flexible plastic panels that vibrate to make sound at the flick of a swit ch were built into wing surfaces. Pure tones produced the best results, but Mr Salmon also tested the effects of playing music. |
