The technology-driven Aurora has been involved in numerous NASA programs since its founding in 1989, and as recently as October 24 announced that it had been awarded a contract to perform a comprehensive evaluation of NASA’s Single-aisle Turboelectric Aircraft with Aft Boundary Layer propulsion aircraft concept, and is also renowned for its work on the D8 and DARPA's XV-24A.
The most significant upgrade to Case IH’s Steiger and Quadtrac articulated tracked tractors for 2018 is a new CVXDrive transmission supplied by ZF, the first such application of a continuously-variable transmission (CVT) in the segment, the company claims.
There is a significant gap between the promises of designers and the expectations of the early adopters of electric propulsion systems. The continual improvement in battery density technology looks to be the bridge to close the gap.
Fiber orientation in composites makes material properties assessments disproportionately more complex than for other materials, such as metals and plastics. To conduct demanding quality-control fatigue tests on glass-fiber composite aerospace specimens, Zwick Roell developed an electro-dynamic, liner-drive testing machine.
Being able to take advantage of a third stream of air that can be modulated to adapt an engine's performance across the flight envelope allows a fighter to access an on-demand increase in thrust or to smoothly shift to highly efficient operations during cruise.
Ford is using a highly engineered lens with 16 precision optical surfaces and 80 facets in the upcoming 2015 F-150's headlamp to re-create as much as possible a daytime quality of light after the sun goes down. The automaker says no other light-duty pickup truck on the road today uses LED headlamps.
Out of the nearly 1500 technical papers being presented this year at the SAE 2014 World Congress & Exhibition, about 200 of them will focus on materials, and from a wide range of angles. In all, there will be 38 technical sessions with an emphasis on materials.
SAE International’s “Theory and Applications of Aerodynamics for Ground Vehicles” provides an introduction to ground vehicle aerodynamics and methodically guides the reader through the various aspects of the subject.
