A MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIME ...

A stratified random sampling technique is used to minimize the time until detection of users of illicit drugs. The stratification is based on likelihood of drug use and importance of the billet occupied. Likelihood of drug used is calculated from fundamental characteristics (e.g., age, sex, education), performance, health and behavior (e.g., relative amount of sick leave, unusual behavior) ...

The project addresses the development of a 64K Massively Parallel P rocessor (MPP) accelerator board together with OS software for installation on a HP-748 workstation providing generation of real-time, high-fidelity, high pixel density and high refresh rate graphic images. The MPP board will be based on associative string processors (ASPs) in a modular massively parallel computer (MPC) ar ...

THE ROTARY WING INDUSTRY HAS STRIVED TO DEVELOP A BEARINGLESS MAIN ROTOR (BMR), HAVING NO MECHANICAL BEARINGS. ALL TRUE BMR SYSTEMS ARE LIMITED BY THE STRENGTH IN STATIC-FATIGUE LOADS VERSUS FLAPWISE FLEXIBILITY, RESULTING IN LIMITED "G" MANEUVERS FROM A HIGHLY RESPONSIVE ROTOR SYSTEM. ATI'S SOFT HUB ROTOR CONCEPT ALLOWS TILTING OF THE ROTOR DISC MOVING THE VIRTUAL HINGE INBOARD ELIMINATING THIS U ...

DEVELOPMENT OF A PLAN AND ITS DEMONSTRATION IN PRODUCING MODERN DATABASE FOR RV TECHNOLOGIES IS PROPOSED BY USING CLOUD MICROPHYSICAL DATA SETS COLLECTED SINCE 1985 OVER THE NORTH AMERICAN CONTINENT AND U.S. ARMY KWAJALEIN ATOLL. THE PLAN INCLUDES THE USE OF AIRBORNE RADAR, MODELING, AND SATELLITE ADDITIONS TO THE PARTICLE SIZE DATA TO CORRELATE PARTICLE SIZE AND LIQUID WATER CONTENT OVER AN EXTEN ...

TO MEET THE KINETIC ENERGY ANTI-SATELLITE (KE ASAT) REQUIREMENTS FOR TIMELY AND RELIABLE KILL ASSESSMENT, AEROMET PROPOSES TO RECOMMEND INNOVATIVE TECHNIQUES IN REAL-TIME KILL ASSESSMENT SPECTROSCOPY. BECAUSE IT CAN BE CRITICALLY IMPORTANT TO ACCURATELY VERIFY SATELLITE ELIMINATION, A KILL ASSESSMENT SYSTEM MUST DISCERN BETWEEN VARIOUS HIT AND MISS PHENOMENA, INCLUDING THE USE OF POTENTIAL COUNTER ...
