In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

THERE EXISTS A NEED FOR FIELD EVALUATION TECHNIQUES ON DAM- AGED RAIROAD TANK CARS, A LARGE PROPORTION OF WHICH ARE OF INSULATED DESIGN CONSISTING OF AN OUTER SHELL, AN INSULA- TION SPACE, AND AN INNER LINER. THESE CARS ARE USED TO HAULMANY POTENTIALLY HAZARDOUS MATERIALS AND CHEMICALS, AND THEREFORE, MUST BE CAREFULLY ASSESSED IN THE EVENT THAT THEYARE DAMAGED. A MAJOR DIFFICULTY ARISES IN ATTEMP ...

A CONCEPT FOR THE DETECTION OF CORROSION IN AGING AIRCRAFT USING ACOUSTIC EMISSION MONITORING IS PROPOSED. CORROSION WILL BE LOCATED THROUGH THE EFFECT THAT IT HAS ON AIRFRAME STRENGTH (10% THINNING RESULTS IN 50% FATIGUE LIFE REDUCTION). ACOUSTIC EMISSION TECHNOLOGY USED ON THE F-111 FIGHTER/BOMBER WILL BE ADAPTED FOR USE ON COMMERCIAL AIRCRAFT. PRELIMINARY CONCEPT TESTING ON A BOEING 720B HAS RE ...

A NOVEL MEANS IS PROPOSED TO SAMPLE, COLLECT AND SELECTIVELYDETECT EXPLOSIVES VAPOR BY TAKING ADVANTAGE OF CERTAIN IONIZATION CHARACTERISTICS IN CONJUNCTION WITH EMPLOYING UNIQUE TANDEM ION MOBILITY SAMPLING, SEPARATION, AND DETECTION ARCHITECTURE. THE METHOD PROPOSED FOR DEVELOPMENTOFFERS SOME UNIQUE ADVANTAGES FOR COLLECTION AND DETECTION OF EXPLOSIVES VAPOR IN ATMOSPHERE AT VERY HIGH SAMPLE FLO ...
