Segelfliegern ist Alexander Müller ein Begriff: er ist dafür bekannt dass er regelmäßig Flüge von 1.000 km oder mehr von Bayreuth aus fliegt (Alexander’s Flüge 2017, 2016 und 2015). Während meines Urlaubs dieses Jahr in Bayreuth hatte ich die Gelegenheit mich mit ihm über diese Fliegerei zu unterhalten. Wir sprechen über seine fliegerischen Anfänge, die EB-29, Streckenplanung, Flugtaktik und Wetterberichte.

Maschinelles Lernen und Neuronale Netze sind im Kontext von Big Data und “Algorithmen” in aller Munde. In dieser Episode versuchen wir die Grundlagen zu erklären. Wie sprechen dabei über den generellen Ansatz, die Umsetzung in Google’s Tensor Flow, Anwendungsszenarien, aber auch das eine oder andere Risiko das mit der Technologie verbunden ist.

In this episode we speak with David Baker, who wrote a fascinating book about spy satellites. We cover the political and military context that drove their development, their (known and suspected) capabilities, methods of recovering the images, as well as typical orbits and the sartellites’ ability to change that orbit for quick repositioning.

As part of my trip to the US earlier this year I visited NASA’s Armstrong Flight Research Center at Edwards Air Force Base. I conducted six interviews over two days, those concerning full scale (“real”) aircraft are in this episode. We start out with Kevin Weinert, with whom we talk about the Adaptive Compliant Trailing Edge project, essentially a flap made of flexible materials to save fuel and reduce noise. Next up is Jim Less, one of NASA’s F-15 and F-18 pilots; we chat about his flying and various research projects where the jets are utilized (you can see this part as a continuation of Episode 73, where we chatted with Dick Ewers). Finally, we talk about flying the MQ-9 and RQ-4 unmanned aerial vehicles with the pilots Scott Howe and Hernan Posada.

As part of my trip to the US earlier this year I visited NASA’s Armstrong Flight Research Center at Edwards Air Force Base. I conducted six interviews over two days, the ones concerning subscale research (i.e., on model airplanes) are in this episode. We start with a conversation about flying wings in general and Prandtl-D in particular with Armstrong’s Chief Scientist Al Bowers. Next, we chat about flutter research and the X-56 with project lead Cheng Moua. Finally, we talk to Matt Moholt about his project, the Spanwise Adaptive Wing project.
