Rocket Flight,olved only by numerical methods. Since this is not the objective of this book, we will treat only those important cases that can be analyzed analytically. This will give rise to an important characteristic quantity the so-called “delta-. budget”. Its relevance will be explored in Sect. ..

,Forschung und Prüfung als Grundaufgaben,Many people have had and still have misconceptions about the basic principle of rocket propulsion. Here is a comment of an unknown editorial writer of the renowned . from January 13, 1920, about the pioneer of US astronautics, Robert Goddard, who at that time was carrying out the first experiments with liquid propulsion engines: . –

,Über die Welleneigenschaften des Elektrons,After a spaceflight, the planetary entry (a.k.a. reentry for entry into Earth’s atmosphere) of a spacecraft is subject to the same aerodynamic and physical laws and equations (see Eqs. (6.3.6) and (6.3.7)) as ascent. One might therefore infer that the circumstances of both situations are the same.
