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.

Spooky season is here, but don't let your annual mammogram scare you. Nearly 30% of women in the U.S. admit to skipping breast screenings out of fear. That's why @gehealthcare engineers decided to better the experience with a mammography system designed by women, for women. Melding comforting design with cutting edge technology, the Senographe Pristina aims to humanize the process for patients, technicians, and radiologists. #BCAM #Mammography #breastcancerawareness
Slice into an additively-made part from @geadditive and you’ll see geometries once thought impossible with traditional manufacturing methods. Why the hype? Engineers can now find greater strength and efficiency through design. #engineering #additive #3Dprinting #manufacturing
This Ultra Performance Heat Exchanger is a perfect example of how small parts can make a HUGE difference. Still in development, the additively manufactured compact heat exchanger is printed with a high-temperature capable, crack-resistant nickel superalloy that will be able to withstand temps that exceed 1,650°F at pressures >3,600 psi. Good thing, too, because it’s headed straight for the inside of a gas turbine, where it’s projected to deliver a 4% improvement in thermal efficiency for supercritical C02 power cycles while improving power output and reducing emissions. Cleaner, more efficient power generation here we come.
Colder weather is on the way. If you’re in Winnipeg, Canada, that means ice testing is too. There, @geaviation test engines are pummeled with sub-zero winds and ice. The harsh conditions on the ground make sure engines are ready to face the elements in the air. #AVgeek #jetengine #engineering
What happens when cutting-edge technology meets unparalleled performance? The CFM* LEAP engine of course. So what makes this engine so amazing? We can think of a few reasons… ➡️It includes the first-ever 3D-woven fiber composite fan blades and fan case ➡️CMCs give it 20% greater temperature capability ➡️It’s the first engine to use 3D-printed parts for critical engine components ➡️It delivers 15% percent better fuel efficiency than its predecessor
