Pratt & Whitney, a division of United Technologies Corp., is collaborating with MTU Aero Engines to build a new generation 23,000 lb thrust Geared Turbofan engine for the Bombardier CSeries aircraft that seats 110 to 130 passengers. The new jet engine is designed for fuel efficiency, low engine noise and environmental performance at low operating costs. The Bombardier is expected to launch its aircraft with the Geared Turbofan engine in 2008. Pratt & Whitney turned to MTU for its expertise in producing low-pressure compressor and engine control units.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
