Boeing and friends go quietly

A three-week flight-test
program recently completed by The Boeing Company and its industry
partners has confirmed the effectiveness of several significant airplane
noise-reduction technologies that will enable airplanes to be even quieter
than they are today.Known as the Quiet Technology Demonstrator 2 (QTD2), the research and
development program is a cooperative commercial aircraft industry project
among The Boeing Company, the General Electric Company, Goodrich Corporation
and NASA. ANA of Japan provided one of its new 777
airplanes for the flight-test activities.
  The flight-test program provided the opportunity for each company to
validate key technologies for incorporation into its own current and future
products. NASA joined the effort to acquire data to support its advances in
propulsion aeroacoustics, landing gear noise, and computational fluid dynamics

“This is exactly what we wanted to achieve,” said Walt Gillette, vice
president, 787 Airplane Development.  “This makes the new 787 better for the
people who will be inside the airplane and better for the people who live in
the communities around airports.”
