The Air Force and other branches of the armed forces require compact and cost-effective, high power (10s of Watts) sources of mid-infrared radiation at wavelengths within atmospheric transmission bands. Thermal issues in solid-state lasers have so farlimited the performance of these devices at long wavelengths. By contrast gas lasers can provide power scalability, however these devices are typica ...

Tactical laser sources delivering high peak power (from multi-MW to TW) in agile optical pulse trains at high pulse repetition frequency (PRF) in the 3.5-4 µm wavelength region are of interest for several military applications including proactive infrared countermeasures (PIRCM), non-lethal munitions, and remote sensing of battlefield threats. To meet the needs for future tactical lasers, Aculig ...

Thulium doped fiber laser near 2 micron is of great interest because of the potential possibility of combining high efficiency, high output power, and retina safety together. This proposal is for the development of new Tm-doped glass fiber for efficient high power 2ƒnmicron fiber laser capable of generating an output power of up to thousands watts. The doping concentration of the proposed glass f ...

The current antennas of choice for earth stations are parabolic reflector antennas such as those used for tracking telemetry and control (TT&C) for the AFSCN. These antennas are required to have horizon-to-horizon, full-hemispherical coverage and oftenseveral antennas are required at each remote tracking station site. A single active hemispherical phased array antenna composed of flat panel suba ...

With the advent of satellite telephone services, it is now feasible to provide secure voice communication to any location on Earth. In a Phase I SBIR for AFRL, Black & Ryan Engineering (BRE) developed VAWCS (Voice Authenticated Wireless CommunicationSystem), a computer model of a Communications Waveform, combining Voice Authentication, Speech Compression, Encryption, and Forward Error Correction ...

REDUCTION OF SATELLITE RADIANCE DATA TO TEMPERATURE PROFILES INVOLVES BOTH DIFFICULT MATHEMATICAL INVERSION ANALYSIS AS WELL AS COMPLICATED DATA PROCESSING. RECENTLY, THE APPLICATION OF THE OPTICAL MEASURE THEORY REPRESENTS A NOVEL APPROACH WHICH PROVIDE A SOLUTION FREE FROM THE NEED OF EXTERNALLY-IMPOSED CONSTRAINTS (KING, 1987). THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A SYSTEMATIC TECHNICAL ...

CAMRIS International will develop a global profile software technology to provide universal access to donor identity, previous deferrals, and travel history to assist data filing continuity of the blood bank collection facilities. Even though software systems to track donor identity, previous deferrals and travel history are available, the knowledge management needs of the Air Force and the Armed ...

Tuberculosis is an ongoing threat to military personnel, and to public health generally. Screening for latent infection continues to be done by the tuberculin skin test; however, to overcome high false-positive and false-negative rates produced by the test,the Air Force is conducting a clinical trial of the QFT-GIT test kit. The clinical trial provides an opportunity for development of a software ...

RESEARCH WILL BE CARRIED OUT TO DEMONSTRATE THE UNIQUE VALUE OF CHEMICALLY BONDED CERAMICS (CBC) AS MATERIALS FOR FABRICATION OF MECHANICAL DETERRENTS TO SYMPATHETIC DETONATION OF MUNITIONS. CBC MATERIALS WILL BE FORMULATED AND CHARACTERIZED FOR SHOCK ATTENUATING PROPERTIES AND FRAGMENT CAPTURE OR VELOCITY REDUCTION PROPERTIES. THE FINAL MATERIAL IS LIKELY TO BE A BINARY MATERIAL (TWO DIFFERENT TY ...

Maintaining stable combustion is a major challenge associated with augmentor design and operation. Numerical simulations of this process are necessary to understand the combustion process and develop control strategies. Thus, it is essential to have reliable reduced kinetic models that are capable of predicting transient combustion phenomena such as ignition and extinction under augmentor operati ...
