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.

VPX Chassis for Missile System

Manchester, NH

Using a hit-to-kill approach, a US Army anti-ballistic missile system called Terminal High Altitude Area Defense (THAAD) is designed to shoot down short, medium, and intermediate ballistic missiles in their terminal phase. The interceptor missile, developed by Lockheed Martin, carries no warhead, but relies on the kinetic energy of the direct impact to destroy the incoming threat.

Preparing for First Flight on Mars

With its eye on Mars, NASA Armstrong has been working on a prototype it refers to as the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-m, which is “a flying wing aircraft with a twist.” It is planned to be ready for launch from a high-altitude balloon later this year and will be released at about 100,000 ft. That altitude will allow it to operate in similar flight conditions as the Martian atmosphere, according to Al Bowers, NASA Armstrong Chief Scientist and Prandtl-m Program Manager.

SIP DC-DC Converters

Premier Magnetics (Lake Forest, CA) has announced additions to its PDCS family of self-contained, single- in-line-package (SIP) DC-DC converters for distributed power applications. The additions to the PDCS product family include two three-pin series. The first is the PDCS01x series, which contains nine models featuring regulated power outputs from 0.75 to 15 watts. They also offer nominal input ranges of 12 VDC and 24 VDC, outputs ranging from 1.5 to 15 VDC, and all are offered with a maximum output current of 500mA. Also being introduced is the three-pin PDCS04x series that includes 10 devices offering a similar range of input and output voltages as the PDC01x series, but with a maximum output current of 1000mA.
