세계 최강의 제트엔진 GE9X, FAA 인증 획득

2020년 10월 14일

20년 전 GE의 엔지니어들은 항공 산업 전 분야의 고객들이 제트엔진으로부터 기대하는 바를 조사했다. 약 300개 이상의 항목을 조사했는데, 최고의 우선순위는 연비(Fuel Economy)였다. 항공사의 전체 운영비 중 약 20%가 연료비었으니 당연할 지도 모른다. 이에 대응하기 위해 GE의 엔지니어들은 보잉과 제휴하여 항공사가 요구하는 제품 개발에 착수했다. 그 결과물이 GE9X 엔진으로 GE9X 엔진을 장착한 보잉 777X 항공기는 연비가 20% 이상 개선되었다. 2020년 9월 25일 GE9X 제트엔진은 미국연방항공국(FAA)의 인증을 받았는데, 이는 GE가 GE9X 엔진의 상용 생산을 시작할 수 있다고 인증한 것으로 매우 중요한 이정표에 도달했음을 의미한다. GE9X 엔진은 현존하는 세계 최강의 제트엔진으로 20세기 말에도 잘 알려지지 않은 적층제조, 즉 금속 3D프린팅 기술을 적용했다. GE항공의 수석

Wind, meet water. In Germany’s Swabian-Franconian Forest, you’ll find the world’s tallest (584 ft) and first-ever wind turbines integrated with pumped storage hydroelectric power. So how does it work? At the base of each wind turbine sits a reservoir. Water flowing downhill from the reservoirs will power the hydro plant when electricity is needed. When there’s an energy surplus, the hydro power will push the water back up the hill to the reservoirs, where it will act as a giant battery for the wind turbines. So no matter if the wind is blowing or not, electricity will always be flowing
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
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
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
If you had X-ray vision, how would you use it? These GE Research engineers use it to capture data from lower-than-surface-level errors in additively manufactured metal parts. Here, they’re analyzing that data, inspecting every layer of metal to find the source of the error. This process helps them design smarter software for additive manufacturing machines. Which means better, stronger parts. That's a pretty good use of a superpower, if you ask us. #AdditiveManufacturing #Data #3DPrinting
