Boeing starts quiet technology demonstrator 2 programme
BY OUR AVIATION CORRESPONDENT
13th August, 2005:SEATTLE: A three-week flight test
programme aimed to cut down noise features of the Boeing
777-300ER, christened, Quiet Technology Demonstrator "2"
(QTD2), started at Boeing’s Glasgow, Montana, test facility.
Several state-of-the-art noise-reduction concepts will be
tested during the programme, the company said in a release.
The tests include chevrons on the engine exhaust ducts and a
new acoustic treatment for the engine inlet, apart from
landing gear noise reduction features , the company said.
The QTD2 is a cost sharing venture between Boeing, General
Electric Company, Goodrich Corporation's Aerostructures
division, and NASA.
Japan’s All Nippon Airways is providing one of its
soon-to-be-delivered 777-300ER airplanes for QTD2 programme.
The firms are validating key technologies for its products,
while NASA aims to acquire data to test some of its advances
in propulsion aeroacoustics and computational fluid dynamics
through the programme.
Earlier a Quiet Technology Demonstrator programme was held
with members of the international aerospace, to verify
significant noise reduction solutions. Walt Gillette, vice
president, 787 airplane development, Boeing Commercial
Airplanes said, "Once we have demonstrated the success of
these technologies, we'll be in a position to rapidly
implement them on specific products, such as the 787.
The Boeing 777-300er completed its maiden flight on February
24, 2003. The 777-300ER is the fourth model of the 777 family.
The 777-300ER aircraft can carry 365 passengers up to a
distance of 7,420 nautical miles (13,742 kilometers).
777-300ER and the 777-200LR were launched by Boeing and GE
Aircraft Engines in February 2002, aimed at customers who
needed service in non-stop routes.
The first 777-300ER aircraft , the ultra long-range,
high-capacity airliner, was delivered in 2004. It has a length
of 73,86 metres and height of 18,56 metres, with a maximum
payload of 69853 kgs. The 777-300ER’s
fuel capacity is 181264 litres.
