On this page you can find some aerospace papers and slides which I originally created for myself to better understand a topic or to give little presentations to others.

Notes on compressible flow
This paper is a brief 40-page summary of the basics of compressible flow written in German. Aerospace students might find some of the explanations in there useful while studying aerodynamics, especially trans- and supersonic flow conditions.
Notes on the lifting line theory
Here are some thoughts (in German) about Prandtl's and Lanchester's lifting-line theory. They may help students who study fluid dynamics or aerodynamics to better understand some aspects of the theory. The paper does not fully explain the topic, it just gives some additional information.
Notes on planetary system formation
There are many theories as to how planets may have formed. Here are a few slides (mostly German) which were used to introduce the topic at a small student college on exoplanets of the German National Academic Foundation in Cologne in 2011. These slides will not give a coherent explanation to somebody new to the topic but some of the animations may be useful for people familiar with the topic - they should feel free to use them in their own presentations.
