A SOLID STATE SWITCH FOR OPERATION AT CRYOGENIC TEMPERATURE IS BEING DEVELOPED THAT WILL PROVIDE MULTI-MEGAWATT POWER CONDITIONING IN THE RAPIDLY EXPANDING FIELD OF LOW TEMPERATURE ELECTRONICS. SINCE EXISTING CONTROLLED SWITCHES ARE NOT DIRECTLY SUITABLE FOR CRYOGENIC OPERATION, ONLY A FUNDAMENTAL APPROACH CAN DEVELOP STRUCTURES CAPABLE OF LOW LOSS AND RELIABLE OPERATION IN THE TEMPERATURE RANGE B ...

COMPOSITE LAMINATES MAY IMPROVE AEROSPACE STRUCTURES, IF THE COMPOSITES DON'T DELAMINATE. DELAMINATIONS RESULT IN UNPREDICATBLE STRENGTH AND STIFFNESS REDUCTIONS AND ARE DIFFICULT TO DETECT. THIS PROJECT PLACES TRIAXIAL ARRAYS OF OPTICAL GLASS FIBER IN LAMINATES. WHEN DELAMINATION OCCURS, THE OPTICAL FIBERS BREAK AND THE DELAMINATION CAN BE DETECTED BY SIMPLE OPTICAL INSPECTION. THE FIBERS ALSO RE ...

INFRARED SYSTEMS ARE NEEDED FOR A VARIETY OF DEFENSE RELATED APPLICATIONS, SUCH AS: SURVEILLANCE, TARGET DETECTION, ACQUISITION AND TRACKING, MISSILE GUIDANCE, ETC. FOR MANY APPLICATIONS SUCH AS THOSE INVOLVING COLD-DIM TARGETS, THESE SYSTEMS NEED TO OPERATE IN THE VERY LONG WAVELENGTH REGION OF THE INFRARED SPECTRUM, E.G. 15-35 MICRONS CUTOFF. IN THIS WAVELENGTH REGION, THE AVAILABILITY OF SUITAB ...
