움파룸파가 만든 3D프린팅 제트엔진
영화 에 나오는 움파룸파 족이 비행기를 만든다면 어떨까? 크기는 일반 항공기보다 작지만 이들에게 어울릴 만큼 기술적으로 뛰어난 혁신적인 제트 비행기가 되지 않을까. 최근 GE의 엔지니어들은 3D 프린팅 기술을 이용하여 작은 제트엔진을 만들었다. 하지만 귀여운 크기와는 달리 이 엔진의 분당 회전수(RPM)는 무려 33,000 에 이르고 있어, 제트엔진이라는 이름에 손색이 없다.

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
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
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
