Friction Stir Welding of Aerospace Materials

AFRL scientists are studying a unique metal joining process— friction stir welding (FSW)—for building major structural assemblies. FSW is a solid-state welding process that forces a spinning tool along the joint line, heating the abutting components by friction and producing a weld joint formed by strong plastic mixing (stirring) of the two components' constituent materials. FSW promises to be a highly efficient and cost- effective alternative to the conventional fusion welding routinely used for joining structural alloys on military and civilian aircraft.

Intelligence Fusion System Tracks Mobile Targets

Current intelligence fusion systems are not accurately and quickly performing the intelligence, surveillance, and reconnaissance (ISR) fusion necessary for tracking moving targets that use camouflage, concealment, and deception to avoid detection. Combatant commanders require a more flexible and responsive capability to engage fleeting and mobile targets.

Integrated Aircraft Oxygen Sensor

Shortly after its takeoff from New York City on July 17, 1996, Trans World Airlines (TWA) Flight 800 exploded over the Atlantic Ocean and crashed. The accident investigation board determined that the center wing fuel tank caught fire and exploded. Although the ignition source remains unknown, it was unquestionably the presence of a combustible fuel/air mixture in the center wing fuel tank that caused the resulting

explosion.

Track-and-Hold Amplifiers For Advanced Test Equipment

The GigaTrack™ family of 2-GS/s track-and-hold amplifiers (THA) from Inphi® Corp. (Westlake Village, CA) delivers ultra-wide 18-GHz analog bandwidth.

The bandwidth, sample rate, and linearity make direct conversion and software-defined receivers possible, and help advance highsample- rate test and measurement equipment. The GigaTrack amplifiers operate from a single -5.2 V power supply and dissipates 1.3 W. They are available in a 49-pin ceramic ball-grid array and in 24-pin QFN packages. The devices are designed for engineers designing next-generation instrumentation, ATE, and military equipment. They enable engineers to replace numerous components in heterodyne receiver architectures with a track-and-hold and a high-samplerate ADC. A direct conversion receiver can serve multiple applications with system differentiation occurring in software or firmware. The GigaTrack family consists of four track-and-hold amplifiers with 2-GS/s sample rates. The ball-grid-array versions offer 18-GHz (small signal) and 15-GHZ (0.5V pp) input analog bandwidths, with settling times >60 ps and power consumption of 1.3 W. Plastic QFN versions offer 13-GHz analog bandwidth (100mV pp).
