GE의 혁신적인 친환경 열차(영문)
지난 수십년동안 미국 정부는 스모그와 공기오염을 줄이기 위해 많은 노력을 해왔다. 환경에 대한 대부분의 규제는 산화질소(nitrogen oxide, NOx)와 미세먼지(particulate matter, PM) 배출 억제책이다. 2015년 1월부터 가장 엄격한 규제인 Tier 4가 발효될 예정이다. 상상을 현실로 만드는 GE는 유일하게 이 규제에 부합하는 열차를 생산했으며 이미 운행중이다.

Thanks to @geadditive , parts with complex geometries can also have simply stunning designs. Just look at this a-CT7 engine mid-frame from the GE Additive Pittsburgh Center. Designed for the a-CT7 turboprop demonstrator engine, this mid-frame used to be traditionally manufactured with 300 individual components and 7 assemblies. With additive, the team got it down to just one piece, one assembly. Part reductions like this can result in higher performance and efficiency levels, as well as significant weight reductions. And that’s the job of an additive manufacturer: making the impossible, possible. #additive #3Dprinting #avgeeks #engineering
I'm Jon Ohman, chief test pilot for @geaviation . Today, I'm taking over our Instagram to give you a behind-the-scenes look at how we run in-air and on-wing tests for our GE9X engine. So if you want some awesome aviation content featuring the largest, most powerful jet engine in the world, you’ve come to the right place. #aviation #flying #avgeek #engineer #testing #Marines
Hi! I'm Kelly Dunham, lead test engineer for @geaviation . Today, I'm taking over GE’s Instagram to give you a behind the scenes look at how we test our jet engines for the first time after they're assembled. Follow along for a special look at how we push the #GE9X , the largest and most powerful commercial jet engine in the world, to its limits here at the Peebles Test Stand in OH. #aviation #avgeek #engineer #jetengines #testing
Today, we’re celebrating all the #WomenInScience who break down barriers to make real progress happen. Happy International Day of Women and Girls in Science 
A marvel of #aviation : the world's largest and most powerful commercial jet engine from @geaviation —the #GE9X . Standing next to this 11-foot diameter monster is GE test operation engineer, Kelly Dunham. Everyday, she comes to work in Peebles, Ohio to test the capabilities of the engine by pushing it to its limits. Kelly runs a slew of different tests such as crosswind testing, hailstorm testing, performance testing and endurance testing. #avgeek #engineer #engineering #aviation
