  • Camera Trio Enhances Solar Storm Forecasting

    Every 100-plus minutes, while orbiting approximately 50 miles above the earth aboard the Coriolis satellite, the experimental Solar Mass Ejection Imager (SMEI) scans the darkness of space seeking sun-generated, magnetic particle clouds bound for earth. Since the SMEI became operational in January 2003, its three charge-coupled device cameras have
  • AFRL Engineers Collaborate With DoD Cyber Crimes Center

    AFRL's Steganographic Intelligence (STEGINT) group is collaborating with the Department of Defense (DoD) Cyber Crime Center (DC3), Linthicum, Maryland, through research, transition, and information exchange sessions on steganographic technologies. The DC3 comprises three organizations: the Defense Cyber Crime Institute (DCCI), the Defense Cyber
  • AFRL Commences GDE-2 Testing

    AFRL engineers began testing the second-generation Ground Demonstration Engine, known as GDE-2, at the National Aeronautics and Space Administration (NASA) Langley Research Center's 8 ft high-temperature tunnel (Hampton, Virginia). The GDE-2 is a hydrocarbon-fueled supersonic combustion ramjet (scramjet) engine featuring a single integrated
  • AFRL Establishes AMIST for Focused Warhead Development

    AFRL and the Department of Energy's Kansas City Plant are collaborating to provide ordnance designers the initiation tools necessary for developing focused warheads, such as the dual-role munition. These advanced weapons will require an interdisciplinary technical solution that incorporates aerodynamic, energetic, warhead, target detection, and
  • AFRL Successfully Tests V-22 Flight Dynamics

    AFRL engineers completed successful wind tunnel tests of the V-22 Osprey, a 6%-scale model, to improve their understanding of the vehicle's flight characteristics. They tested the model in the vertical wind tunnel at different orientations; propeller speeds; and sideslip, nacelle, and blade angles. To simulate movement through the air, the
  • AFRL Successfully Tests Automated Refueling Subsystem

    AFRL completed a successful flight test of an automated aerial refueling ( AAR), inner- loop control laws (IL CLAWS) system. A flight control computer (FCC) hosted the IL CLAWS system, which interfaced with the Calspan Learjet variable stability system (VSS) using discrete, analog signals. As part of the test, engineers installed the FCC on a
  • AFRL Designs Tapered Ground Plane for SUAV

    AFRL scientists designed, built, and tested a tapered ground plane design. The team used an important in-house facility--namely, the Radiation and Scattering Compact Antenna Laboratory--as a resource for testing verification. The improved ground plane reduces the susceptibility of a Global Positioning System patch antenna installed on board a small
  • AFRL Demonstrates Transparent ZnO Electronics

    AFRL scientists demonstrated transparent microelectronic circuits using nanocrystalline zinc oxide (ZnO) transistors. Large-area electronics for electromagnetic, chemical, and mechanical sensors, as well as large-display electronics, can be more useful in compact system applications such as unmanned air vehicles (UAV) if the sensors are also
  • AFRL Commences GE VAATE Core Compressor Testing

    AFRL engineers began testing General Electric's (GE) long-range strike (LRS) Versatile Affordable Advanced Turbine Engine (VAATE) core compressor at AFRL's Compressor Research Facility (CRF). These tests will further develop the front three stages of the dual-use core compressor to increase part speed efficiency, investigate concepts that mitigate
  • AFRL Scientist Leads Polymer Effort Based on DNA Derived From Biowaste Materials

    AFRL is making significant contributions to bioengineering through the investigation of a new class of polymer, or "biopolymer," based on DNA (deoxyribonucleic acid) derived from biowaste materials. Dr. James G. Grote, of AFRL's Materials and Manufacturing Directorate, assembled and led a team to investigate this new biopolymer and its potential
