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.

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.

Implementing Secure Command and Control in Unmanned Systems

Unmanned vehicles are at the forefront of an evolution, especially with the proliferation of the Internet of Things. After decades of serving mission-critical applications in government and defense, the command and control (C2) capabilities of advanced wireless data communications have begun to migrate into the public safety, research, and commercial markets. The robust and secure infrastructure necessary for the eventual proliferation of unmanned vehicles is slowly being realized. Today, however, industries such as public safety, agriculture and oil and gas are being eyed as key markets that can benefit from the use of Remotely Piloted Aircraft (RPA). For several applications, such as wildfire monitoring and border protection, RPAs can even be used to protect people and save lives.
