우주 카우보이, 별을 향해 로프를 던지다
NASA는 NASA Innovative Advanced Concepts (NIAC) 프로그램의 우승자로 워싱턴 소재의 한 회사가 내놓은 카우보이 우주선 아이디어를 채택해 약 1억 원의 상금을 지급했다. ‘무한의 밧줄(Tethers Unlimited)’이라는 이름을 가진 이 회사는 자신들이 제안한 아이디어인 ‘그물로 소행성을 잡아 회전을 멈추게 할 수 있는 우주선’을 1년 동안 개발해왔다.

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.
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
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
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
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
