Boeing will use a new technique that ultimately will save fuel on its new 787-9 Dreamliner.
Aviation Week’s Guy Norris writes that the company is making miniscule holes in the surface of the plane’s horizontal and vertical tails, a first for any large production commercial aircraft.
“The technology, to be applied at the leading edges of the vertical and horizontal tails, sucks in boundary layer air through tiny holes in the skin, helping to delay the transition of the air from smooth, laminar flow to turbulent flow – thereby cutting drag,” he wrote.
