3-Phase Single-Step Power Correction in MilAero Systems

As OEMs seek advantages in Size, Weight, Power and Cost (SWaP-C), focus is shifting to advancements in power electronics. Gaining an advantage requires close attention not only to performance requirements such as power factor and current distortion, but also size, weight, efficiency and cost. This is no small feat, given that power solutions must seamlessly handle the multi-step regulation and isolation of electronic circuits, a costly and complex process commonly required for AC to DC conversion in high-performance power applications.

Using Sensor Technology to Combat Legacy Issues in Defense Avionics

Reliance on aging military platforms has become a global concern and military aircraft today are expected to remain in service for longer than their original life cycles. This is partly as a result of a post-Cold War slowdown in purchasing of new material in the late 1990s, as well as cuts in defense spending. Indeed, the current USAF fleet is the oldest in its history, with the average age of aircraft being 26 years.

Counterfeit Electronics in the DOD Supply Chain

Counterfeit semiconductor devices entering the Department of Defense (DOD) supply chain continue to pose risks to many of our country’s most sophisticated aerospace and defense systems. However, considerable progress is being made by the DOD, industry and academia in developing approaches to help eliminate these devices before they are put into critical systems.

Sandwich Cores for the Future

The search for lighter weight, stronger materials to construct airplanes and spacecraft remains as important as ever. But it takes a long time for new materials in aerospace structures to make their way into production designs. Capital is one reason; it is harder to take risks when it costs so much to develop new composites. Another is the long approval process from regulatory agencies due to safety constraints.

Making AESA Radar More Flexible

A modular, building-block approach brings greater design flexibility to Active Electronically Scanned Array (AESA) radar technology, simplifying system integration, and permitting rapid first-line repair with no downtime using standard off-the-shelf components.

Until recently, AESA radar was utilized almost exclusively by prime aerospace contractors within their own proprietary systems. These customized solutions were relatively costly and time-consuming to manufacture, and not reconfigurable to alternative uses.

Developing Secondary Surveillance Radar Automated Test Equipment

Unlike primary radars, Secondary Surveillance Radar (SSR) calculates the range and azimuth of a target, such as an aircraft, using a bidirectional communication link to gather information. Engineers use SSR in both military and civil aviation, with the former incorporating an identifying friend-or-foe system.
