TRANSPORTATION SYSTEM STUDIES REQUIRE IN-SERVICE INSPECTION USING NONDESTRUCTIVE EVALUATION (NDE) TECHNIQUES FOR FLAW DETECTION AND CHARACTERIZATION. IN CASES WHERE SUCH DEFECTS ARE SMALL COMPARED WITH THE THICKNESS OF THE SECTION, ULTRASONIC METHODS ARE CONSIDERED TO BE THE MOST SUITABLE. IT WOULD BE IDEAL TO MAKE SUCH MEASUREMENTS REMOTELY WITH A SYSTEM COMBINING THE STRONG FEATURES OF ULTRASONI ...

A SYSTEM UTILIZING THE FREE-WING CONCEPT HAS BEEN DESIGNED FOR LIGHT AND VERY LIGHT WING-LOADING AIRCRAFT THAT ACCOMMODATES MODERATE TO HEAVY TURBULENCE WITHOUT TRANSMITTING HIGH GUST LOADINGS TO THE AIRFRAME OR THREATENING LOSS OF CONTROL. THE PROJECT WILL TEST THE SYSTEM IN A RESEARCH VEHICLE APPROXIMATING THE DESIGN CRITERIA SET FORTH IN 14 CFR, PART 103; THE RESEARCH VEHICLE IS UNMANNED.

A NAVIGATION DATA REPORTER (NAVREP) WHICH PROVIDES THE BEST ESTIMATE OF USER POSITION FROM AVAILABLE NAV AIDS IS PROPOSED AS A SOURCE OFTRACKING DATA FOR DEPENDENT SU TSURVEILLANCE IN OCEANIC AIRSPACE OR AREAS WITH ATC COVERAGE GAPS. NAVREP ALGORITHMS ARE TO BE DEVELOPED FOR ON BOARD OR GROUND-BASED NAVIGATION DATA INTEGRATION AND F DFAULT DETECTION/ISOLATION. ADDITIONAL ACTIVITY WILL FOCUS ON: 1) ...

CSE PROPOSES TO APPLY ITS DEMONSTRATED, PATENDED PROTOTYPE PRESSURE-SENSOR TECHNOLOGY TO HBRID 3 FACE AND OTHER ATD AREAS, ALLOWING ACCURATE RECORDING TRIAXIAL ANGULAR ACCELER ATIONS AS WELL AS AREA-PRESSURE-TIME HISTORIES ON HEAD, FACENECK, THORAX, ABDOMEN, KNEE, AND ANY OTHER ATD REGION. PRESSURE SENSORS WILL CONSIST OF SEGMENTED STRIPS, VESTS, ORGLUED-ON PATCHES. DATA WILL BE PROCESSED BY MDAS ...

COST REDUCTION HAS DRIVEN THE INCREASED USE OF LARGE CARGO CARRIERS (LCC'S) IN MARITIME TRANSPORATION. THE LCC'S INCREASED DRAFT, BEAM AND LENGTH ARE WELL RECOGNIZED, BUT THE PROPORTIONATE INCREASED HEIGHT OR AIR DRAFT REQUIRE MENT IS OFTEN IGNORED. THE CLEARANCE FOR MANY BRIDGES, DESIGNED FOR PRE-WORLD WAR II VESSELS ARE NOW EXCEEDED BY THE LCC. COMPETITION HAS FORCED PILOTS TO UTILIZE EVERY AVAI ...

THIS PROPOSAL DESCRIBES A SIX-MONTH PROGRAM FOR THE INVESTIGATION INTO THE TECHNICAL FEASIBILITY OF A DEPLOYABLE, DOOR-MOUNTED PAD FOR ENHANCING THE PROTECTION LEVEL AFFORDED FRONT SEAT OCCUPANTS BY VEHICLES STRUCK IN THE SIDE DOOR AREA. THE CONCEPT PROPOSED FOR INVESTIGATION IS AN INFLATABLE STRUCTURE INTEGRATED INTO A PRODUCTION-CONFIGURED SMALL CAR DOOR. UPON IMPACT OF THE DOOR A STORED GAS OR ...

SEVERAL METHODS OF RAPIDLY SCREENING AIRLINE PASSENGERS AND BAGGAGE FOR EXPLOSIVE DEVICES ARE PROPOSED. TWO OF THESE METHODS USE NONLINEAR DEVICE DETECTION (NLDD) TO DETERMINE THE PRESENCE OF ACTIVE OR PASSIVE SEMICONDUCTOR DEVICES WHICH MAY BE PART OF AN ELECTRONIC BOMB FUZE. ANOTHER TWO DETECT THE PRESENCE OF RUNNING OSCILLATORS WHICH ARE LIKELY SUBSYSTEMS OF A FUZING DEVICE.
