The automated inspection of gas turbine components has proven to be difficult due to their complex geometry. While ultrasonics has demomstrated excellent capabilities in detecting and characterizing the erosion and corrosion on turbine components from the hot effluent gases, it's application details laborious alignment procedures for the ultrasonic transducer during inspection. The need for automa ...

RESEARCHERS ARE CONSTRUCTING TEST PANELS OF FIBER-REINFORCED-POLYMER HONEYCOMB (FRPH), INSTRUMENTED WITH STRAIN GAUGES AND ACOUSTIC SENSORS FOR CONDUCTING NON-DESTRUCTIVE EVALUATION (NDE) ACOUSTIC EMISSION (AE) AND PHYSICAL LOAD TESTING. FRPH STRUCTURAL ELEMENTS ARE HIGH-STRENGTH, LIGHTWEIGHT, CORROSION-RESISTANT, TOUTH, AND RESILIENT; THEY CAN BE MACHINE-MANUFACTURED USING A HIGH-VOLUME, CONTINUO ...

THE OBJECTIVE IS TO DEVELOP A KNOWLEDGE-BASED ASSISTANT FOR THE SOFTWARE ENGINEERING (SE) PROCESS. A CASE-BASED-REASONING (CBR) APPROACH TO KNOWLEDGE ELICITATION IS PROPOSED AS A SENSITIVE AND EFFECTIVE STRATEGY TO DERIVE AND REPRESENT CRITICAL KNOWLEDGE. PHASE I WILL DEMONSTRATE THE FEASIBILITY OF USING A CBR APPROACH TO DEVELOPING A KNOWLEDGE-BASED ASSISTANT FOR THE EXTENSIVE AND COMPLEX TASKS A ...

IN RECENT YEARS THE CORROSIVITY OF THE TACTICAL WHEELED VEHICLE ENVIRONMENT HAS BECOME MORE SEVERE DUE TO INCREASED USE OF ROAD SALTS, INCREASED ATMOSPHERIC POLLUTANTS (SO(2) AND NO(X)), AND CHANGES IN CLIMATIC CONDITIONS IN SELECTED GEOGRAPHIC REGIONS OF THE WORLD. THE COMBINED EFFECTS OF THE ABOVE CONDITIONS AND MARINE SALTS HAVE SIGNIFICANTLY DECREASE THE LIFE EXPECTANCY OF SELECTED VEHICLES AN ...

Reliability and lifetime performance data for environemntal control systems (ECS) is limited. Real-time tests require 5-15 years, and results often apply only to obsolete technology. Accelerated life testing (ALT) is a means by which reliability data may be obtained quickly and at a reasonable cost. A primary difficulty with ALT of ECS units is that typical service conditions impose multiple stres ...

THE OVERALL OBJECTIVE OF THE PROPOSED RESEARCH IS TO INVESTIGATE THE USE OF THE ELECTRICAL POTENTIAL DROP TECHNIQUE AS AN ACCELERATED TEST METHOD FOR DETERMINING THE STRESS CORROSION CRACKING RESISTANCE OF HY-130 STEEL WELDMENTS UNDER CATHODIC PROTECTION IN NATURAL SEAWATER AT AMBIENT TEMPERATURES. WELDS WILL BE DEPOSITED IN 1-INCH THICK HY-130 STEEL BUTT JOINTS. COMPACT TENSION FRACTURE-MECHANICS ...
