PARIS, France - The GE-P&W Engine Alliance continues to access emerging technologies to enhance performance, weight, reliability, and cost of ownership of its GP7200 family of turbofan engines, including the GP7267 and GP7275 for the Airbus Industries proposed four-engine A3XX aircraft and the GP7167, designed for the Boeing Growth 747. The GE-P&W Engine Alliance is a joint company between GE Aircraft Engines and Pratt & Whitney. Testing of a core rig is targeted to begin in October 1999, with the first complete engine to enter testing in July 2002. Plans call for certification of the engine at 75,000 pounds of thrust by the U.S. Federal Aviation Administration and the Joint Aviation Authorities of the European Economic Community in November 2003. At entry into service on the Airbus A3XX-100, the engine will be rerated to 67,000 pounds (298 kN) of thrust and designated the GP7267. It will enter service on the A3XX-100R and A3XX-200 at 75,000 pounds (333 kN) thrust, designated as the GP7275. The GP7267 and GP7275 engine models will both have a 110-inch-diameter fan that incorporates wide-chord, hollow titanium blades. Both models will have a bypass ratio of 8 to 1 and an overall pressure ratio of 46 to 1. The GP7167 is a slightly shorter (169 vs. 179 inches) and lighter-weight (11,300 vs. 13,100 pounds) engine with a 99-inch-diameter fan. The GP7167 will have a bypass ratio of 7 to 1 and an overall pressure ratio of 43 to 1. The GP7167, GP7267 and GP7275 incorporate a common core consisting of a nine-stage high-pressure compressor (HPC) that is a scaled derivative of the GE90 and E3 HPCs. All three also incorporate a single annular combustor designed to limit emissions to 40 percent below the 1998 standards set by the International Civil Aviation Organization and a two-stage high-pressure turbine (HPT). The low-pressure compressor (LPC) of the GP7267/GP7275 comprises four stages while the GP7167 LPC comprises three stages. The GP7267/GP7275 low-pressure turbine (LPT) comprises five stages while the GP7167 LPT comprises four stages. "We are extremely pleased with our progress to date," said Bruce Hughes, Alliance president. "We anticipate a strong market for this class of aircraft and the GP7000 family of engines will be well prepared to power them." Under the terms of the Alliance agreement, Pratt & Whitney is responsible for the design and fabrication of the fan, LPC, LPT and gear train, and GE Aircraft Engines is responsible for the engine core (HPC, HPT and combustor).
