Watch A Giant An-124 Condor Land At St. Maarten's Famous Airport For Hurricane Recovery. The fan blades feature steel leading edges and glass-fibre trailing edges to better absorb bird impacts with more flexibility than carbon fiber. Further inspections found two additional radial gears with cracks. The LM9000 is an aeroderivative gas turbine available in two options; the LM9000 without water augmentation outputting 66 MW (89,000 hp) at a 42.4% efficiency before cogeneration, and the LM9000 with water augmentation outputting 75 MW (101,000 hp) at a 42.7% efficiency before cogeneration. [13], Problems with GE90 development and testing caused delays in Federal Aviation Administration certification. Explore a career with us. It has received orders for more than 700 GE9X engines from airlines including Cathay Pacific, Emirates, Lufthansa, Etihad Airways and Qatar Airways. General Electric's GE9X turbofan engine took to the air for the first time at Southern California Logistics Airport on March 13th, 2017. The Guinness Book of World Records has officially declared the General Electric GE9X as the world’s most powerful jet engine! The fan diameter of the original series being 123 in (310 cm), and the largest variant GE90-115B has a fan diameter of 128 in (330 cm). The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 lbf. The GE90 was developed from the NASA 1970s Energy Efficient Engine, a prototype variant of the General Electric CF6. As a result, GE90 engines can only be air freighted in assembled form by outsize cargo aircraft such as the Antonov An-124, presenting unique problems if, due to emergency diversions, a 777 were stranded in a place without the proper spare parts. GE9X has been undergoing ground testing since 2016, with 355 hours and 375 cycles already under its belt, including some challenging cold environment testing. Voices is a network for GE’s US supporters interested in the company’s impact in their communities and in issues that impact the company. [3][14] The improved version entered service with Air France in May 2004. [3] Its 61:1 overall pressure ratio should help provide a 5% lower thrust specific fuel consumption (TSFC) than the XWB-97 with maintenance costs comparable to the GE90-115B. The Airworthiness Directive requires compliance by taking remedial measures within five days of receipt of the AD.[35]. ETOPS approval should need 3,000 ground-test cycles, to be completed for service introduction. However, GE also needed to increase core power to improve net thrust at high flight speeds. By embracing diverse teams and perspectives, we are better equipped to build a world that works. The engines should be modified to a final certifiable configuration standard before the maiden flight, delayed after the previously expected June 26. This emergency AD was prompted by reports of two failures of transfer gearbox assemblies (TGBs) which resulted in in-flight shutdowns (IFSDs). [24], The GE9X should increase fuel efficiency by 10% over the GE90. [17] The 777-300ER has also been seen as a 747-400 replacement amid rising fuel prices given its 20% fuel burn advantage. Read the latest GE financial news releases and stories. This makes the engine lighter, and allows the low pressure (LP) fan and booster to spin faster to better match its speed with the LP turbine. The compressor is designed with 3D aerodynamics and its first five stages are blisks, combined bladed-disk. In October 2003, a Boeing 777-300ER broke the ETOPS record by being able to fly five and a half hours (330 minutes) with one engine shut down. © document.write(new Date().getFullYear()) Acton Media Inc. All Rights Reserved. [4] Until November 2015, it accumulated more than 8 million cycles and 50 million flight hours in 20 years. Initial service was affected by gearbox bearing wear concerns, which caused the airline to temporarily withdraw its 777 fleet from transatlantic service in 1997. However, when the V2500 ran into technical problems, sales of the CFM56 took off. [8], The bigger and higher-thrust -115B version that powers the second generation 777 (-300ER, -200LR, and -200F) had its first run at the GE facility in Peebles, Ohio in November 2001.[9]. The nacelle has a maximum diameter of 166 in (4,200 mm). It is just the beginning of the journey: GE has received orders for more than 700 GE9X engines. It is wider than the fuselage of a Boeing 737. [20] It first flew on March 13 with the previous design of the VSV external lever arm. We build intelligent devices, data analytics, applications and services to enable healthcare practitioners to deliver care more efficiently and with better outcomes. [11] Its type certification is planned for the fourth quarter of 2018. The compressor and high pressure turbine are made from powdered metal. Investigation revealed that the failures were caused by TGB radial gear cracking and separation. Lifting a play from western 5th generation fighter development methodology, China is facing its own challenges with 5th-gen fighter sensor fusion in the air. Explore GE’s recent and historic SEC filings. It entered service with British Airways in November 1995. [2], The GE90-115B is powerful enough to fly GE's Boeing 747-100 testbed with the other engines at idle, an attribute demonstrated during a flight test. [27] The aircraft, with GE90-115B engines, flew from Seattle to Taiwan as part of the ETOPS certification program. [13] The bypass ratio is planned for 10:1. [27], The high pressure (HP) compressor is up to 2% more efficient. The third engine is in Peebles, while the fifth will travel to Winnipeg for icing tests starting by end of 2017 while three other engines are currently under assembly. It is one of three options for the 777-200, -200ER, and -300 versions, and the exclusive engine of the -200LR, -300ER, and 777F. GE Aviation is a world-leading provider of aircraft engines, systems and avionics. It incorporates GE’s most advanced technologies that have been developed over the last decade to make it the most fuel-efficient engine in its class while also delivering unmatched performance. View our service capabilities General Electric GE9X The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777 , with thrust ratings from 81,000 to 115,000 lbf (360 to 510 kN). The GE9X is an engine set to feature on the up and coming Boeing 777x series. [11], As one of the three available engines for the new Boeing 777, the GE90 was an all-new $2 billion design meant to handle transoceanic routes, in contrast to the offerings from Pratt & Whitney and Rolls-Royce which were modifications of existing engines. It entered service with British Airways in November 1995. Creating the energy technologies of the future and improving the power networks that we depend on today. The engine will now enter into an intensive flight test program with the company aiming to achieve certification in 2019. [11] During extreme test conditions for the FAA 150 hr block test, the variable stator vane (VSV) actuator lever arms failed and their redesign led to a 3–month delay. NTSB and FAA investigations were begun to determine the cause; initial findings were reported in September 2015.
