First Growth GE90 Engine on Schedule for May 1996 Certification
EVENDALE, Ohio - Development of the 92,000 pound thrust GE90-92B is proceeding on schedule with engine certification set for May 1996 and entry into service that will coincide with the introduction of the first Boeing 777 "B" market aircraft in December of that year.
GE Aircraft Engines accelerated development of the first GE90 growth engine based on the outstanding results achieved in ground and flight test programs. In early 1994, in its current configuration, the GE90 set a new world record by achieving more than 110,000 pounds of thrust. Overall, GE90 development engines have achieved and sustained thrust levels in excess of 100,000 pounds for more than 50 hours.
The higher thrust GE90 is being offered both to new customers and as an upgrade option for existing "B" market customers. The engine will provide airlines with many significant advantages, including increased capability in hot climates and at high altitude airports, and will provide for continued evolution of the longer-range "B" market and stretch 777s. The growth step will be accomplished with minimal changes to the engine's low pressure system and the high pressure turbine. More than 80 percent of the testing required for certification at 92,000 pounds was accomplished as part of the initial GE90 certification program. The U.S. Federal Aviation Administration just certified the GE90-85B at 84,700 pounds thrust, and the engine will enter service with British Airways at 76,000 pounds takeoff thrust next September.
"We are delighted with the entire GE90 test program," said Russ Sparks, general manager of the GE90 program. "We've proven, without question, that the GE90 is the only new commercial engine with the future already built in."
From the beginning, the GE90 has been designed as a 90,000+ pound thrust engine. Because the GE90 enters service substantially derated, customers are assured of high reliability and low maintenance cost. In addition, the engine will be able to grow with the 777 family and, thus, provide airlines all the benefits and cost savings of commonality throughout their 777 fleets.
Snecma of France, FiatAvio of Italy, and IHI of Japan are revenue-sharing participants in the GE90 development program.
