747 8: Boeing

February 13, 2011 by staff 

747 8, Contrary to the Dreamliner, Boeing released in 2007, but did not take off for two and a half years; the new 747-8 jumbo jet unveiled in Everett on Sunday is not an empty shell.

“We will deploy an aircraft that has darn near ready to fly,” Boeing commercial airplanes chief Jim Albaugh said in an interview. “I think it will fly within three or four weeks.”

A preliminary visit to the interior of the giant passenger plane, the Intercontinental 747-8, revealed the final preparations for flight-testing.

The cckpit is ready for pilots to take command. A label just above the steering yoke driver reads: “Boeing 001 flight test.”

In the cabin, cavernous, Boeing has installed door hardware and dozens of black barrels interlocked so that during the upcoming flight tests, the water serves as ballast can be pumped to simulate the various loads.

Outside, the air is spectacular because of what Albaugh called “that big bump on the top.”

This latest model of the iconic jumbo jet, which flew the first version in 1969, has a bump forward fuselage widened with a row of windows that extends all the way back on the wings.

The 747-8 is an airliner large commercial aircraft developed by Boeing Commercial Airplanes. Officially announced in 2005, the 747-8 is the fourth generation of Boeing 747 version with lengthened fuselage, redesigned wings and improved efficiency. The 747-8 is the largest version 747, the largest commercial aircraft manufactured in the United States, and the aircraft is the longer passengers worldwide.

The 747-8 is available in two main variants: the Intercontinental 747-8 (747-8I) for passengers and the 747-8 Freighter (747-8F) for freight. The 747-8F made the first flight model February 8, 2010. Delivery of the first cargo plane was delayed several times and is now scheduled for mid-2011, deliveries of passenger model is to begin in late 2011 or early 2012. In December 2010, orders for the 747-8 is 107, including 74 of the freighter version, and 33 of the passenger version.

Boeing has reviewed the larger capacity versions of the 747 at several times during the years 1990 and 2000. The 747-500X and 600X-, proposed at the Farnborough Air Show 1996, would have stretched 747 and used a 777-wing spin, but has not attracted enough interest to enter into development. In 2000, Boeing offered the 747X and 747X Stretch derivatives as alternatives to the Airbus A3XX. It was a more modest proposal than the previous-500X and-600X. The 747X is increasing the 747 to 229 m scale (69.8 m) by adding a segment to the root. The 747X was to carry 430 passengers up to 8,700 nm (16,100 km). The 747X Stretch would be extended to 263 ft (80.2 m) long, allowing it to carry 500 passengers up to 7,800 nm (14,400 km). However, the 747X family was unable to attract enough interest to go into production. Some of the ideas developed for the 747X were used on the 747-400ER.

The freighter version of the 747-8 has attracted orders from several airlines for cargo; the plane has the advantage of similar training and parts interchangeable with the Boeing 747-400F. In addition, the 747 has a long history as a cargo plane of success, and despite his age is still popular among traders because it has greater capacity and greater range than the cargo planes.

Compared to the freighter version, the passenger version of the 747-8 has not seen much success, with far fewer orders. Airlines, including Emirates and British Airways orders considered Intercontinental 747-8, but opted to purchase the Airbus A380 instead. In addition, there are 8 VIP orders for the 747-8I by different clients. Boeing Chairman and CEO Jim McNerney acknowledged in a conference call for investors on Boeing April 23, 2008 that he would like to see more orders for the passenger version of the 747-8.
