ALLOYS BASED ON INTERMETALLIC TI(3)AL HAVE BEEN RECOGNIZED AS POTENTIAL MATERIALS TO BE DEVELOPED FOR HIGH TEMPERATURE APPLICATIONS IN ADVANCED WEAPON SYSTEMS AND AEROSPACE VEHICLES. TITANIUM ALUMINIDES POSSES LOW DENSITY, HIGH STRENGTH AND GOOD OXIDATION RESISTANCE, BUT SUFFER FROM POOR ROOM TEMPERATURE DUCTILITY. THE MAJOR CAUSES FOR LOW ROOM TEMPERATURE DUCTILITY HAVE BEEN IDENTIFIED AS (1) EXT ...

MILLITECH PROPOSES TO DESIGN A COMPACT OFFSET CASSEGRAIN ANTENNA SYSTEM TO BE USED AT A WAVELENGTH OF 8 MM FOR CLOUD RESEARCH. THE SYSTEM WILL BE DESIGNED TO GIVE THE LOWSIDELOBE LEVELS CHARACTERISTIC OF AN OFFSET REFLECTOR WHILE GIVING POLARIZATION ISOLATION BETTER THAN 20 DB. THE TRADE-OFF BETWEEN HIGH POLARIZATION ISOLATION AND COMPACT SIZE WILL BE RESOLVED BY USING A GAUSSIAN OPTICS LENS ANTEN ...

AN IMPROVED LASER DOPPLER TECHNIQUE TO MONITOR EYE ATTITUDE USING AN OPTRA DEVELOPED 2-FREQUENCY HE NE LASER IS PROPOSED. THE HETERODYNE APPROACH MAKES IT POSSIBLE TO UNAMBIGUOUSLY MEASURE EYE ATTITUDE BY INTEGRATING THE DOPPLER SHIFT OF LIGHT SCATTERED OFF THE CORNEA OR SCLERA. THE HIGH SENSITIVITY OF THIS METHOD MAKES IT POSSIBLE TO OPERATE A LOW LIGHT LEVELS--WELL BELOW THE EYE SAFETY EXPOSURE ...

THE OBJECTIVE OF THIS PHASE I PROGRAM IS TO INVESTIGATE THE FEASIBILITY OF DEVELOPING A NEW CLASS OF IMAGING DETECTORS THAT DIFFER SIGNIFICANTLY FROM THOSE CURRENTLY AVAILABLE IN THAT THE NEW DEVICE EMPLOYS A NOVEL HIGH RESOLUTION MULTI-ANODE FEEDTHROUGH PLATE (FTP) WITH APPROXIMATELY 4000 ANODES/MM(2). THIS HIGH SPEED 2-D DETECTOR ARRAY IS EXPECTED TO BE HIGHLY SENSITIVE, AND OFFERS A FAST SCANNE ...

THE VORTICITY OPTICAL PROBE (VOP) IS A RECENTLY DEVELOPED TECHNIQUE WHICH USES MICROSCOPIC CLEAR SPHERICAL PARTICLES CONTAINING EMBEDDED PLANAR REFLECTIVE CRYSTALS TO SAMPLE THE LOCAL VORTICITY OF A LIQUID FLOW IN WHICH THEY ARE SUSPENDED. LASER LIGHT REFLECTIONS FROM THE PARTICLES, DETECTED EXTERNALLY TO THE FLOW, HAVE BEEN USED IN THE PAST TO DETERMINE ONE OR TWO COMPONENTS OF A SINGLE SPHERE'S ...

A NEED EXISTS TO DEVELOP A RELIABLE, COST EFFECTIVE POWER PLANT AND STORAGE SYSTEM FOR AN ELECTROMAGNETIC AIRCRAFT LAUNCHER. THIS SYSTEM CAN BEST BE DEVELOPED AROUND A HIGH ENERGY DENSITY FLYWHEEL COUPLED TO AN ADVANCED ELECTRIC GENERATOR. CONVENTIONAL POWER GENERATION CONCEPTS WOULD BE USED TO CHARGE THE FLYWHEEL BETWEEN LAUNCHES. THE CONTRACTOR WILL REVIEW THE CURRENT STATE-OF-THE-ART IN THE KEY ...

THE INTRODUCTION OF THE TURBINE POWER PLANT AS A TORPEDO PRIME MOVER CREATED A SPEED AND TORQUE MISMATCH BETWEEN THE POWER PLANT AND THE PROPELLER. CONVENTIONAL GEARTRAIN TECHNOLOGY IS CURRENTLY USED TO TRANSFORM ENGINE SHAFT OUTPUT TO THAT REQUIRED BY THE PROPELLER. THE INHERENT MESH NOISE GENERATED BY THE GEARSETS IS UNDESIRABLE. THE RESEARCH PROPOSED HEREIN WILL INITIATE THE DEVELOPMENT OF NONC ...
