Electrocoat Primer System

PPG Industries
Pittsburgh, PA

PPG Industries’ aerospace coatings group has installed an electrocoat primer system at the US Coast Guard Aviation Logistics Center in Elizabeth City, North Carolina. The technology, custom-designed to protect the facility's aerospace parts, has reduced the time needed for primer application, processing, and full-cure.

Maximizing Thermal Cooling Efficiencies in High-Performance Processors

Despite the continuous development of new, higher performing processors, the thirst for increased embedded computing capability remains unquenched. In fact, it seems like Moore’s Law may have slowed when it comes to frequency but increased in terms of driving processor core and field programmable gate array (FPGA) LUTS counts. The previous need for fewer frequency increases has become a need for increased core counts, faster front side bus speeds, and greater support chip integration, all of which drive continually rising power requirements. Meeting these ever increasing "compute density escalations" while simultaneously maximizing thermal cooling efficiencies requires innovative packaging solutions.

Stand-Off Scanning and Pointing with Risley Prisms

With the ever increasing threat of improvised explosive devices, both in the military arena and the civilian realm, there is a growing demand for technologies with the ability to detect explosives and their precursors from a safe stand-off. While a wide variety of technologies have been investigated for this application, laser-based spectroscopic techniques designed to detect chemical traces on personnel, vehicles and other objects have garnered a lot of attention. These laser-based techniques include Raman spectroscopy, laser induced breakdown spectroscopy (LIBS), diffuse reflectance spectroscopy (DRS), and photothermal spectroscopy (PTS), among others. Laser-based approaches concentrate a large amount of power on a single target location, which enables reasonable signal-to-noise ratio (SNR) to be obtained despite the 1⁄R2 drop-off in return signal strength (where R represents stand-off distance).

Getting It Right with Composites

"Composite design and analysis is a highly integrated activity,” said Chris Gear, Chief Technology Officer & Senior Technical Fellow for GKN Aerospace. He noted that how composite material is placed, how it moves, how it cures, and the quality and conformance of the product are all interrelated. All of these factors are considered in the final release of the data for manufacturing, according to him, aided by design-for-manufacturing (DFM).

Regional and Bizjets Refined and Redefined

There is definitely a degree of overlap in the regional and business jet sectors, both in terms of airframes and the engines that power them. At the high end of the market are aircraft such as the Boeing 737 BBJ and Airbus A319 Corporate Jet, which typically carry up to a dozen VIP passengers in spacious luxury, but which in airline service carry around 130 passengers.
