Seminar paper from the year 2015 in the subject Engineering - Aerospace Technology, grade: 1,0, University of Applied Sciences Frankfurt am Main, language: English, abstract: The purpose of this paper is to evaluate the challenges and chances of biofuels in an aviation context. It begins by providing a brief history on biofuels in general and in aviation specifically. It is followed by an overview of the main driving forces for the aviation industry to invest in biofuels and their development. After that, different available biofuels and their segmentation in first, second, and third generations is shown in more detail along with a basic overview on the production processes that exist on the market. Based on the given information, first the challenges and after that, the chances, for the aviation industry on investing in aviation biofuels is shown into detail. The paper claims that the biofuels still have major issues as there is no real alternative on the market or in development that can substitute crude oil-based jet fuel up to 100%. Current biofuels can only be used as mixtures with conventional jet fuel. However, the biggest issue, namely that biofuels cannot be certified in aviation because of their specifications, is solved with second-generation biofuels. The main challenges are still to find a sustainable biofuel that can be used without changes to existing aircraft propulsion technology and nothing ensures that this will be possible in the necessary timeframe until the crude oil finally starts to become less available. That point in time is constantly updated, but only based on statistical data. It is not known at what point in time this will be exactly. However, there are a number of opportunities. They range from having an alternative to substitute conventional jet fuel for emission reduction reasons to the investment of an aircraft operator to the production of biofuel itself. This could be for the sake of entering new markets or just to integrate the f

There on her forearm, next to a small brown birthmark, were six tattooed numbers. 'Do you remember me now?' he asked, trembling. She looked at him again, as if giving weight and bone to a ghost. 'Lenka, it's me,' he said. 'Josef. Your husband.' During the last moments of calm in prewar Prague, Lenka, a young art student, falls in love with Josef. They marry - but soon, like so many others, they are torn apart by the currents of war. In America Josef becomes a successful obstetrician and raises a family, though he never forgets the wife he thinks died in the camps. But in the Nazi ghetto of Terezin - and later in Auschwitz - Lenka has survived, relying on her skills as an artist and the memories of a husband she believes she will never see again. Now, decades later, an unexpected encounter in New York brings Lenka and Josef back together. From the comfort of life in Prague before the occupation to the horrors of Nazi Europe, The Lost Wife explores the endurance of first love, Aviation Biofuels.
