Let [tau] [much greater than] T and let the leading and trailing edges
be propagating in free space.
Owls, however, possess no fewer than three distinct physical attributes that are thought to contribute to their silent flight capability: a comb of stiff feathers along the leading edge of the wing; a soft downy material on top of the wing; and a flexible fringe at the trailing edge
of the wing.
Each trailing edge
is 36 metres long and is being delivered in four sections each, because of its size, requiring a purpose-built lorry.
The processing of leading and trailing edges
is ideally suited to mechanical surface finishing process because of the true radius produced, but care must be taken to maintain the chordal width of the blade.
"At some point, the blades become too thin to do that, so they peel off some skin at the end of the blade and let the air run over the trailing edge
," said Benson.
The wing was designed without traditional leading and trailing edges
, which usually have drag-producing hinges and crevices.
Some of these experiments involve duplicate samples of materials placed on both the leading and trailing edges
of LDEF to assess the affect of chemically reactive atomic oxygen emanating from the top of the atmosphere.
Technologies to be developed and tested during demonstration flights will include adaptive wing trailing edges
and ceramic matrix composite acoustic engine noises.
A Contiroll labeller transfers the reel-fed labels in the container and applies UV-cross-linkable hotmell to the leading and trailing edges
. This glue is then activated by UV irradiation inside a tunnel.
During the test on the 787 Dreamliner static test airframe, the wing and trailing edges
of the airframe were subjected to its limit load, the highest loads expects to be seen in service.
The final test took place on 21 April, when the wing and trailing edges
were subjected to their limit load.
