Dave McNally, Aerospace Engineer, Air Traffic Management, and Kapil Sheth, Aerospace Research Engineer, Ames Research Center, Moffett Field, California Convective weather, such as severe thunderstorm activity, is the leading cause of delay in the U.S. National Airspace System. Two NASA-developed tools – the Dynamic Weather Routes (DWR) tool and a national implementation of DWR called the National Airspace System Constraint Evaluation and Notification Tool (NASCENT) – will help pilots identify and evaluate opportunities for more efficient paths around convective weather and other airspace constraints. Dave McNally and Kapil Sheth are the lead developers of the technologies. DWR was tested operationally by a major US airline for three years.

The Fourth Revolution in Manufacturing

The fourth industrial revolution, or Industry 4.0, is all about going digital. But the term – and the basic idea behind it – are not new. First used in 2011 at Hannover Fair in Germany, the term Industry 4.0 originates from a question posed by the German government to its country’s manufacturing industry leaders: What is the next stage of evolution for manufacturing?

Spring-Loaded Screws

PEM® ReelFast® SMTPFLSM™ surfacemount, spring-loaded, captive panel screws from PennEngineering®, Danboro, PA, install permanently on printed circuit boards to provide secure attachment and allow for subsequent access whenever necessary. The all-metal assemblies mount in one piece on boards using the pick-and-place method, and install in the same manner and at the same time as other surface-mount components prior to the automated reflow solder process. They are supplied on tape and reel, and are compatible with existing SMT automated installation equipment. For Free Info Visit http://info.hotims.com/61058-110

Thermal Cameras Reveal Materials’ Secrets

Scientists at the Department of Energy’s Oak Ridge National Laboratory are pioneering the use of infrared cameras to image additive manufacturing processes in hopes of better understanding how processing conditions affect the strength, residual stresses and microstructure of 3D-printed parts.

Researchers Turn Solar Energy into Electrical Power Using Photo-Bioelectrochemical Cells

A new paradigm for the development of photo-bioelectrochemical cells has been reported by researchers from The Hebrew University of Jerusalem, in Israel, and the University of Bochum, in Germany. The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.

NASA Engineers Tapped to Build First Integrated-Photonics Modem

A NASA team has been tapped to build a new type of communications modem that will employ an emerging, potentially revolutionary technology that could transform everything from telecommunications, medical imaging, and advanced manufacturing to national defense. The space agency’s first-ever integrated-photonics modem will be tested aboard the International Space Station beginning in 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration, or LCRD. The cell phone-sized device incorporates optics-based functions, such as lasers, switches, and wires, onto a microchip — much like an integrated circuit found in all electronics hardware. Once aboard the space station, the so-called Integrated LCRD LEO (Low-Earth Orbit) User Modem and Amplifier (ILLUMA) will serve as a low-Earth orbit terminal for NASA’s LCRD, demonstrating yet another capability for high-speed, laser-based communications.

Product of the Month

MSC Software Corp., Newport Beach, CA, announced the release of Marc 2015 nonlinear and multiphysics simulation software. Enhancements include new material models to simulate complex dynamic behavior of elastomers, permanent deformation of thermoplastics, and anisotropic plastic deformation in metal forming. The software provides a cohesive contact behavior that allows users to apply a finite stiffness in the normal and tangential direction, improving stress results in the contact zones and the overall deformation. A new family of elements has improved bending behavior compared to traditional lower order triangular and tetrahedral elements, and can be used for either compressible or nearly incompressible behavior. Two new global adaptive meshing methods are included, as well as improvements to Mentat, the user interface of Marc.
