Textron Lycoming of Stratford, Connecticut is incorporating the latest in advanced technology into turboshaft and turboprop engines for near term commercial service. The level of cold section technology being incorporated is the already demonstrated next generation of axi-centrifugal compressor beyond that which was developed for the U.S. Army T800, 0.9 MW turboshaft engine in the late 1980s. The compressor evolution is given special emphasis. The hot section technology is a robust, simplified, low cost, commercial endurance derate of the tri-service; US Army, US Navy, US Air Force and Textron Lycoming joint core engine [1] now on test. The new 2 MW commercial engine has substantially reduced fuel consumption, is lighter, and is smaller than today’s best engines. Engineering development is now underway and certification is slated to be completed in 1996.

ZUSAMMENFASSUNGSeit 2008 klagten F-22-Raptor-Piloten wiederholt über hypoxieähnliche Symptome im Flugbetrieb, die unter dem Begriff „hypoxia-like events“ in die Literatur eingegangen sind. Nach Verlusten von Piloten und Maschinen hatte im Mai 2011 die gesamte F-22-Flotte der USA Startverbot. Gleichzeitig sind intensive Untersuchungen zu möglichen Ursachen der Zwischenfälle eingeleitet worden, die bis heute andauern. Indessen häuften sich diese Ereignisse auch bei weiteren Hochleistungsflugzeugen. Alle Versuche der US Air Force, US Navy und NASA, die Ursachen der nunmehr als „unexplained physiological events“ (UPEs) oder „physiological events“ (PEs) bezeichneten Vorfälle aufzuklären, schlugen ungeachtet intensiver Bemühungen fehl. Momentan stellen PEs eine der größten Herausforderungen für die Flugmedizin überhaupt dar, die es in Zusammenarbeit mit Piloten, Ingenieuren sowie anderen Fachleuten auf diesem Gebiet zu lösen gilt. Ohne Fortschritte beim physiologischen Inflight-Monitoring und Anpassung des Trainings der Piloten wird dies jedoch unmöglich.

SummaryAs a terror tactic, suicide terrorism is one of the most lethal as it relies on a human being to deliver and detonate the device. Suicide terrorism is not confined to a single region or religion. On the contrary, it has a global appeal, and in countries such as Syria, Iraq, Afghanistan, and Pakistan it has come to represent an almost daily reality as it has become the weapon of choice for some of the most dreaded terrorist organizations in the world, such as ISIS and al-Qaeda. Drawing on over two decades of extensive field research in five distinct world regions, specifically the Middle East, Western Europe, North America, Russia, and the Balkans, the author discusses the origins of modern day suicide terrorism, motivational factors behind suicide terrorism, its global migration, and its appeal to modern-day terrorist groups to embrace it as a tactic.
