Boeing 767 more fuel efficient than Airbus 330, analysis finds
Article Type: Mini features From: Aircraft Engineering and Aerospace Technology: An International Journal, Volume 80, Issue 3.
The Boeing Company recently released a 53-page study prepared by Conklin & de Decker Aviation Information claiming that a commercial 767 aeroplane is substantially more fuel efficient than the larger Airbus 330.
The study conducted by the independent aviation research company, and funded by Boeing, used published data to calculate the fuel consumption of flying a fleet of 179 767-200ER and Airbus 330-200 aeroplanes over a 40-year service life. The purpose of the analysis was to provide a clear comparison between the KC-767 Advanced Tanker (AT), based on the 767, and its major competitor in the US Air Force's KC-135 Tanker Replacement Program. The winner of the KC-X competition will begin recapitalising the service's ageing refuelling inventory by building 179 next-generation tankers.
The study reportedly showed that the 767 fleet burned 24 percent less fuel than the A-330s and would save approximately $14.6 billion in fuel costs. That number is significant since the Air Force spent approximately $6.6 billion on aviation fuel costs in 2006.
“Senior Air Force leaders have said that when a barrel of oil increases by $10, it costs them about $600 million a year,” said Mark McGraw, Vice President, Boeing Tanker Programs. “So it is critical, especially with rising fuel prices, that the Air Force's next refuelling tanker meet or exceed their requirements and be as efficient as possible. That aircraft is the right-sized KC-767 Advanced Tanker.”
Boeing recently submitted its Final Proposal Revision and is offering an advanced derivative of the future 767-200 Long Range Freighter. The modern aircraft will have a 767- 200ER fuselage; 767-300F freighter wing, landing gear, cargo door and floor; and a 767-400ER flight deck and flaps.
The KC-767AT will provide critical fuel to receiver aircraft closer to the fight while requiring fewer bases to support tanker operations. It also will carry three times more cargo and passengers than the KC-135 without sacrificing the operational flexibility delivered by a medium-sized aircraft.
Boeing has been designing, building, modifying and supporting tankers for nearly 75 years, and is flying KC-767s today with more than 330 flights and nearly 1,000h on the tanker platform. The team producing the KC-767AT includes Honeywell, Rockwell Collins, Vought Aircraft Industries, Pratt & Whitney, Smiths Aerospace, Spirit AeroSystems and Delta TechOps. Nation-wide, the program will support 44,000 American jobs and 300 suppliers.
Boeing will produce the KC-767 AT at its facilities in Everett, Wash., on the existing commercial line where more than 950 highly reliable and maintainable 767s have been built. Installation of military refuelling systems and flight test activities will take place at the company's finishing center in Wichita, Kan.
