Customizing Computer-Aided Design

MIT researchers have devised a technique that “reverse engineers” complex 3-D computer-aided design (CAD) models, making them far easier for users to customize for manufacturing and 3-D printing applications.

Northrop Grumman and Airbus Partner on “Wing of Tomorrow” Program

Northrop Grumman Corporation recently finalized a Cooperation and Research Agreement to work closely with Airbus on the Wing of Tomorrow program. The three-year agreement expands the current Northrop Grumman relationship with Airbus and explores complex composite wing stiffener forming automation with out-of-autoclave material systems through an investment in equipment, test articles and engineering support.

Cartilage-Like Material Enables Structural Battery

A structural battery prototype incorporates a cartilage-like material to make the batteries highly durable and easy to shape. The idea behind structural batteries is to store energy in structural components like the wing of a drone.

Study Could Help Aircraft Avoid Dynamic Stall

University of Illinois researchers are studying the physics of dynamic stall so that it can be used beneficially and reliably by aircraft. The problem has been studied at low speeds but at higher speeds, the process becomes significantly disorganized and difficult to understand.

NIF Experiments Support Warhead Life Extension

It was a normal morning for design physicist Madison Martin at Lawrence Livermore National Laboratory (LLNL). At 7:45 a.m., she settled into her classified workstation with a cup of tea to check the results of a numerical calculation she ran overnight. If the calculations proved correct, the experiment she was designing on the National Ignition Facility (NIF) would deliver the data her colleagues needed to verify that a refurbished nuclear warhead would perform as expected.

Discovery Could Lead to Munitions That Go Further, Much Faster

Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide. This discovery coincides with the one of the Army's modernization priorities: Long Range Precision Fires. This research could lead to enhanced energetic performance of metal powders as propellant/explosive ingredients in the Army's munitions.

Navy Launches Virtual Training Tech for Aircraft Carrier Flight Deck Crews

One of the most dangerous environments in the U.S. Navy is the deck of an aircraft carrier. Catapult systems that can remove limbs, furious engines, whipping propellers, and high winds create a hectic environment. The driving force behind all of these activities is helping a pilot land an aircraft on a short slab of pitching steel in the middle of the ocean. Although pilots are the stars of the show, they could not accomplish their missions without the support of flight deck crews, who are responsible for safely launching and recovering aircraft.

High-Speed Switched Serial Fabrics Improve System Design

Well into its third decade of widespread deployment, VME adopted the new VXS gigabit serial interface, clearly representing the most significant leap in backplane data transfer rates throughout its entire history. Because VXS delivered such a dramatic improvement in embedded system performance, the use of gigabit serial technology was extended to create VPX. The OpenVPX initiative followed shortly thereafter, as risk-averse government agencies mandated the need for industry-wide standards. The hallmark of any successful standard is that it continues to evolve with technology, and none offers a better example than VME’s evolution to VXS and VPX.

High-Speed Real Time Recording Systems

In today’s world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task that requires specialized hardware and intelligent application software. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 5 GB/sec and higher, the system developer has to consider the limitations presented by the recorder’s operating and file systems, the limitations of disk drive technology, the hardware interfaces, and the RAID controller technology.

Putting FPGAs to Work in Software Radio Systems

FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.
