Composites Self-Heal at Very Low Temperatures

Scientists developed a method of allowing materials, commonly used in aircraft, to self-heal cracks at temperatures well below freezing. A healing efficiency of more than 100% at temperatures of -60 °C was obtained in a glass fiber-reinforced laminate, but the technique could be applied across a majority of self-healing composites.

Navigation System Uses Existing Cell Signals – Not GPS

Researchers developed a highly reliable and accurate navigation system that exploits existing environmental signals such as cellular and Wi-Fi, rather than the Global Positioning System (GPS). The technology can be used as a standalone alternative to GPS, or complement current GPS-based systems to enable highly reliable, consistent, and tamper-proof navigation in autonomous vehicles such as unmanned drones.

NASA’s Folding Wing Reduces Drag and Increases Efficiency

NASA’s Spanwise Adaptive Wing (SAW) concept permits the outboard portions of the wings to move to the optimal position during operation. This could increase efficiency by reducing drag, and increasing lift and performance. The ability to achieve an optimal wing position for different aspects of flight may also produce enough yaw control to allow for rudder reduction on subsonic and supersonic aircraft.

700 MHz - 6 GHz Benchtop Power Amplifiers

AR (Bothell, WA) now provides up to 350 watts of linear output power over the 0.7 to 6 GHz instantaneous frequency band in one benchtop amplifier housing when driven with a signal generator output of 0 dBm. Class A designs can be provided when linearity and ∞:1 output protection is required, or in Class AB configurations when lower cost and higher efficiency are needed with slight sacrifices in linearity and output VSWR protection. Units have a digital display and all amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet. These instruments are used for EMC, wireless, or EW applications.
