These Space-Age Ceramics Will Be Your Jet Engine’s Next Cup of Tea

May 15, 2015
Humans have been living with ceramics for 25,000 years. We’ve been using them for cups, pipes, pottery and many other handy everyday objects. But the light, strong, and heat resistant material has one fatal flaw, which has kept it confined mainly to the cupboard. “When you hit it, it fails catastrophically,” says Krishan Luthra, chief scientist for manufacturing and materials technologies at GE Global Research in New York. “I thought it would be the Holy Grail if we could get it inside machines, and get more power and savings out of our engines. It could really make an impact.”

Just Like Dimples on Golf Balls, Reshaping Aircraft in Flight Could Make Planes Fly Better

April 01, 2015
In the not-too-distant future, airplanes will scythe into the wind with an airframe that can virtually streamline its shape using nothing but air. In pursuit of this goal, researchers at NASA and Boeing moved a vertical tail from an old 757 inside the world’s largest wind tunnel at NASA Ames Research Center in California to test technology called active flow control. Active flow uses tiny air jets to reduce friction and turbulence across flight surfaces.

Here Comes the Jet! Lost Film About the Jet Engine’s Top Secret Origins Found in GE Archives

March 09, 2015
In 1942, a group of GE engineers working in secret for ten months built America’s first jet engine. Their mission was to win the war, but they ended up shrinking the world. “They called us the Hush-Hush Boys,” says Joseph Sorota, one of the last living veterans of the project, who just turned 95.

GE Develops Jet Engines Made From Ceramic Matrix Composite

March 04, 2015

Engineers at jet engine proving grounds in Ohio are using a jet engine GE developed for Boeing’s Dreamliner to test engine parts made from a new ceramic super-material called ceramic matrix composite. The material could help pave the way to more fuel efficient planes.

首架GEnx为动力的波音787-9梦想飞机交付美国联合航空公司

September 15, 2014

美国俄亥俄州EVENDALE,2014年9月4日------首架以GEnx-1B 发动机为动力的波音787-9梦想飞机已于近日获得美国联邦航空管理局的适航证,并于9月4日交付给美国联合航空公司。这次交付代表着两个第一:第一架由GEnx发动机提供动力的波音787-9梦想飞机交付;第一架交付给北美航空公司的波音787-9飞机。

"首架采用GEnx发动机的波音787-9梦想飞机的交付是该发动机项目的又一个重要的里程碑,"GE航空集团GEnx/CF6发动机项目总经理Tom Levin表示。"以GEnx-1B为动力的波音787-8飞机已经运营两年多了,表现极为出色。我们期待着以GEnx发动机为动力的波音787-9梦想飞机也将有同样出色的表现。"

Ge9x发动机风扇叶片将采用新的设计和材料

September 11, 2014

美国俄亥俄州EVENDALE,2014年8月26日------用于波音777X飞机的GE9X发动机将采用比任何在役的GE宽体发动机更少、更薄的复合材料风扇叶片。为此,GE正在设计使用新一代碳纤维复合材料的新型复合材料风扇叶片。

"自GE为GEnx发动机设计新型复合材料风扇叶片到现在已经有十年的时间了,"GE90/GE9X发动机项目总经理比尔.米尔汉姆(Bill Millhaem)表示。"碳纤维复合材料在这十年中不断进步,这让GE的工程师能够设计出更薄的GE9X风扇叶片,其强度与我们目前使用的复合材料风扇叶片相当。更少、更薄的叶片将增强气流并使风扇更轻、更高效,有助于提升GE9X发动机的整体性能和燃油效率。"

新材料采用硬度更高的碳纤维和新型环氧树脂。其前缘材料还将从钛合金改为钢合金,进一步提升叶片的强度。

去年,GE工程师对全尺寸GEnx叶片进行了材料测试,取得了积极的结果。对新型材料的测试将在本季度继续进行,为明年进行新型GE9X叶片测试做好准备。

在成功的GE90-94B、GE90-115B和GEnx发动机设计基础上,GE9X将是第四代复合材料风扇叶片。GE的工程师将结合不断改进的空气动力学设计,继续完善GE9X风扇叶片的最终设计。

Watch this airspace

September 04, 2014
Your plane is on the Sydney airport tarmac in line for takeoff. You look out of the window and spot another aircraft, apparently stalled mid-runway. You fire up your phone and tweet in frustration: “Stuck behind disabled plane in Sydney. Melbourne seems many hours away. #Qantas”
In Qantas Integrated Ops, they’re monitoring the twitter feed for aviation news and will hop into the conversation: “Just waiting for an incoming flight to clear. We’ll have you in the air in five minutes.” Soothed by social media, you open the newspaper. There’s nothing like knowing what’s going on.
