Maintenance Personnel

Next generation aircraft propulsion systems inevitably place higher thermal loads on jet fuel since it is used as primary heat sink for engine, hydraulics, avionics and other on-board systems. Increased fuel temperatures prior to combustion may lead to deposit formation in fuel systems and combustion sections. This limits engine performance, puts a burden on maintenance personnel and increases operational costs. U.S. Air Force, industry and academia therefore decided to team up and start the development of thermally stable fuels in the late eighties. This initiative eventually led to the formulation of an additive package capable of improving fuel thermal stability with 100°F (56°C). Although significant experience has been gained with the additive in military applications, the potential in the much larger civil market is yet untapped. Recent evidence however indicates the ability of the additive to reduce particulate emissions and component wear as well. This paper describes the experiments that were undertaken with a stationary gas turbine located at Delft University of Technology (DUT). The proprietary additive in question, provided by Shell Aviation (SAV), was added to commercial Jet A-1 kerosene. Repeatable tests were conducted to characterize the exhaust aerosol and combustor deterioration of the test-rig with standard and dosed fuel. The outcome of the experiments indeed suggests a role of the stability additive in soot (precursor) formation processes. Short-term cleaning effects inside the combustor were not observed however.

Exhaust Particulate

X-ray fluorescence (XRF) was required to analyze vehicle exhaust particulate samples deposited on filters to determine the trace element content of the emissions. These samples were collected as part of a study to assess the role of vehicular particulate emissions in the Denver “Brown Cloud” problem. This study was an adjunct to an earlier study of vehicular gaseous emissions at high and low altitudes. The earlier program involved complete certification testing of a fleet of twenty five (25) 1970, non-catalyst vehicles but did not include analysis of exhaust particulate emissions. Consequently, a subset of the original vehicles was selected for retesting at high and low altitudes. A complete analysis was necessary to compare the ratio of particulate carbon to lead in the vehicle particulate emissions at the Denver test site.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
