Critical aircraft structures are susceptible to hidden corrosion. Find-it and fix-it approaches are inefficient as it relates to managing the problems associated with corrosion. More comprehensive corrosion information may be obtained using data fusion from several detection and evaluation methods. To this end, microwave, conventional and pulsed eddy current data from a multi-layer corroded panel, representing an aircraft lap joint, are fused and used as inputs to a structural analysis ...
THE NUCLEAR AND SPACE INDUSTRIES REQUIRE ELECTRONICS WITH HIGHER TOLERANCE TO RADIATION THAN THAT CURRENTLY AVAILABLE. THE RECENTLY DEVELOPED 300 DEGREES C ELECTRONICS TECHNOLOGY BASED ON JFET THICK FILM HYBRIDS WAS TESTED UP TO 10 TO THE NINETH POWER RAD GAMMA (SI) AND 10 TO THE FIFTEENTH POWER NEUTRONS/CM SQUARED. CIRCUITS AND INDIVIDUAL COMPONENTS FROM THIS TECHNOLOGY ALL SURVIVED THIS TOTAL DOSE ALTHOUGH SOME DEVICES REQUIRED 1 HOUR OF ANNEALING ...
