glass-fibre<\/a> plates at varying intervals, on both the outer and inner surfaces. The deformation properties of the transition skin can be adjusted by means of the soft, flexible rubber and the positioning of the rigid glass-fibre strips. The researchers endeavoured to keep local deformations to a minimum so that the glass-fibre composites and rubber did not separate.<\/p>\n\n\n\nThe final tests using a demonstrator showed that the wing skin being tested is very hard-wearing and can be deformed to a large extent, In the event of extreme deformation, the only thing that needs care is the paintwork, to make sure that it does not crack. The use of a flexible skin on wing leading edges has been shown to be feasible. Further testing will be carried out to check the extent to which noise and drag can actually be reduced using this technique and determine the maximum load limit of the skin.<\/p>\n","protected":false},"excerpt":{"rendered":"
Part of the noise from aircraft is generated by the wing. Where high-lift devices and control surfaces meet the wing, there is an abrupt transition between these aerofoils and the air flowing around them to the fixed part of the wing. Aerodynamic studies have shown that such transitions are responsible for some of the noise. Could a flexible surface between the wing and the moving surfaces reduce noise in this area?
