Super vacuum die casting to the rescue via improved quality, reduced costs

Due to greater demand for lighter weight products to reduce fuel consumption, carbon dioxide emissions, and cost, industries are continuously improving existing products. The net shape capability of emerging technologies presents challenges to traditional casting design, which begs the question: can existing casting methods continue as an industry staple while methodologies improve?

Military, suppliers focus on long-term technical advances, compatibility

Equipment developers are moving quickly to ensure that military users will have long-term access to boards and modules that provide higher performance, easy replacement, and reduced costs. Board and system designers adopting new technologies are standardizing interconnection layouts to ensure that boards designed by various suppliers can be used to upgrade systems as technology advances.

Boeing’s ecoDemonstrator 757 used to get the bugs out

Boeing is in the midst of several months of flights with its ecoDemonstrator 757 in a first-round effort to evaluate new technologies in 2015 that are expected to reduce environmental effects on natural laminar flow as a way to improve aerodynamic efficiency while reducing noise and carbon emissions.

Flight propulsion goes electric

Small, electrically driven propellers spaced along wing leading-edges could benefit both small and medium-size aircraft

Taming of the drones

While unmanned systems are already transforming the way that modern warfighting is conducted, the commercial sector is still at the starting gate. That said, personal UAV ownership is expanding at an exponential rate, as small, stable, UAVs enter the market.

Altair optimizes 3D-printed structures for complex, lightweight designs

The company expects to better support the use of additive manufacturing, or 3D printing, by releasing new OptiStruct solver capabilities for topology optimization. The company claims this new technology is the first tool developed specifically for designers of lattice structures.

NASA BLI propulsor may leapfrog current high-efficiency designs

Fuel efficiency—and the economic and ecological benefits associated with it—continues to be the white rabbit of the global aviation industry. While engine builders look toward composites and electrification, and airframe designers toward lightweighting and aerodynamics, engineers at NASA’s Glenn Research Center recently completed testing of a novel concept: the boundary layer ingesting propulsor.

Fungus-inspired improvements in battery performance

Carbon fibers derived from a sustainable source, a type of wild mushroom, and modified with nanoparticles have been shown to outperform conventional graphite electrodes for lithium-ion batteries.

Embraer's first E190-E2 jet takes off early

E-Jets E2s are based on the proven platform of the current-generation E190, but with more advanced technologies applied such as new aerodynamically advanced high-aspect ratio wings and geared turbofan engines from Pratt & Whitney.

Rolls-Royce, Purdue partner on jet engine design

Rolls-Royce will designate Purdue as a University Technology Partnership, which will initially encompass two research centers in the areas of advanced thermal management systems and advanced compressor systems.
