THE OBJECT OF THIS EFFORT WILL BE A REDUCTION IN WEIGHT AND PRODUCTION COSTS, RELATING TO THE CURRENT 5.56 BRASS CASED AMMUNITION CARRIED BY THE U.S. MILITARY FORCES. IT WILL INVOLVE THE EVALUATION OF MATERIALS AND DESIGNS USED BY AMMUNITION TECHNOLOGIES INC (A.T.I.) IN THE DESIGN AND CONSTRUCTION OF THE M193 PLASTIC CARTRIDGE CASE DEMONSTRATED AT FORT LEWIS WASHINGTON IN SEPTEMBER OF 1988. THESE ...

DESIGN AND FABRICATION OF SOLID-STATE DIRECTION-INDICATING APPARATUS, WITH TILT-IMMUNITY, THAT PROVIDES AN AUDIBLE OR TACTILE INTERFACE WITH THE USER. REDUCED SIZE TO ALLOW ENCAPSULATION IN A TYPICAL WALKING CANE. A DEVICE WILL BE DESIGNED THAT WILL PROVIDE A VISUALLY IMPAIRED PERSON WITH AN INDICATION OF HORIZONTAL DIRECTION, WITH RESPECT TO THE EARTH'S MAGNETIC FIELD. THE DEVICE WILLALSO SIGNAL ...

THE PROPOSED WORK PROVIDES FOR A DEMONSTRATION OF THE FEASIBILITY OF A NEW TYPE OF FLAT-PLATE STRESS SENSOR FOR OBSERVATION OF SEA-ICE STRESSES. THE SENSOR IS DESIGNED TO MEASURE NORMAL TENSILE AND COMPRESSIVE STRESSES WHILE OVERCOMING THE ACCURACY LIMITATIONS OF EXISTING ICE STRESS MEASUREMENT TECHNIQUES. A FIBER-OPTIC TECHNIQUE IS USED TO OBSERVE STRESS. THIS TECHNIQUE PROVIDES A SIMPLE, LOWPOWE ...

ALTHOUGH CONVENTIONAL MASS-SPRING RETARD SENSORS ARE INEXPENSIVE, THEIR POOR RELIABILITY USUALLY REQUIRES THE USE OF TWO DEVICES IN PARALLEL TO ASSURE SWITCH CLOSURE. THE USE OF TWO DEVICES, HOWEVER, HAS AN ADVERSE AFFECT ON S&A SAFETY. G-SWITCHES USED AS RETARD SENSORS IN THE FMU-139 BOMB FUZE ARE CURRENTLY A MAJOR PROBLEM AREA IN THAT PROGRAM. THEIR POOR RELIABILITY IS DUE PRIMARILY TO IMPERFECT ...

ATOMIZED LIQUID SPRAY FILTRATION SYSTEMS ADDRESS THE DEFICIENCIES OF THE CURRENT BARRIER-TYPE FILTRATION SYSTEMS. PRESSURE DROP ACROSS THE LIQUID SPRAY IS LOW BECAUSE THERE IS NO OBSTRUCTION TO THE AIRFLOW; THUS THE SYSTEM WILL REQUIRE LESS SPACE AND CAN OPERATE WITH CONVENTIONAL VENTILATION FANS. THE PRESSURE DROP DOES NOT INCREASE WITH TIME BECAUSE THERE IS NO BUILDUP OF PARTICULATE ON A FILTER ...

THE DEVELOPMENT OF AN OPTICAL METHOD IS PROPOSED FOR THE IMMEDIATE APPLICATION OF INVESTIGATING THE EFFECTS OF SMALL PARTICLES ON THE EVOLUTION OF A LAMINAR BOUNDARY LAYER FORMED AS FLOW PASSES THE NOSE OF AN UNDERWATER VEHICLE. DURING PHASE I, WE WILL DEMONSTRATE THE FEASIBILITY OF DEVELOPING SUCH A METHOD. A TWO-DIMENSIONAL FLOW FACILITY, WITH A STREAMLINED OBSTACLE TO SIMULATE THE FLOW PAST AN ...

WE PROPOSE TO DETERMINE THE FEASIBILITY OF A SOFT LANDING, HYDRAULICALLY-POWERED PENETRATOR FOR DEPLOYING SEISMOMETERS AT DEPTHS OF 30 TO 100 METERS BENEATH THE SURFACE OF THE DEEP OCEAN BOTTOM. SEISMOMETERS DEPLOYED AT THESE DEPTHS WILL BE BETTER COUPLED TO THE SEDIMENT AND WILL BE ISOLATED FROM VLF/ULF NOISE SIGNALS ASSOCIATED WITH SURFACE WAVES AT THE SEDIMENT/WATER INTERFACE AND FROM CURRENT I ...
