GE90 engine establishes new thrust record during tests
22 November 2001
During its initial ground tests, a GE90 engine a new thrust record for a jet engine, reaching 120,316 pounds of thrust. The record-setting thrust level was established on November 19 during tests of a GE90-115B development engine at GE Aircraft Engines' outdoor test complex near Peebles, Ohio.
The engine reached 120,316 pounds of thrust and then ran at a steady state of 117,446 pounds of thrust. During the first phase of ground tests this autumn, the engine is targeted to complete 150 hours of testing to measure thrust, performance, cross-wind capability, and fan blade stress levels.
"We first put the engine to test on Friday, set a new thrust record on Sunday, and broke it again on Monday," said Chaker Chahrour, general manager, GE90 Project Department. "This achievement is a testimony to the effectiveness of GE Aircraft Engines' new engine development team and its methodology."
The GE90-115B, the world's most powerful turbofan engine, is the exclusive powerplant for Boeing's longer-range 777-300ER and -200LR twinjets.
In early 2002, the engine is scheduled to begin flight tests on GE's 747 flying testbed at Mojave in California. The GE90-115B is scheduled for FAR33 type certification (rated at 115,000 pounds of thrust) by the US Federal Aviation Administration and the European Community's Joint Airworthiness Authorities in 2002.
Certification, first delivery, and entry into service of the 777-300ER is set for 2003. Air France, Japan Airlines, All Nippon, EVA, International Lease Finance, and GE Capital Aviation Services have ordered a total of 49 firm 777 longer-range aircraft.
In total, 17 customers have ordered 204 firm and 52 option GE90-powered 777 aircraft, with a firm engine value of more than $6.7 billion.
The GE90-115B features swept fan blades, a high-efficiency high-pr…
