Modern Propulsions for Aerospace

History

Hermann Oberth father romanian-german (Romanian citizen by German ethnicity) of missiles, has an inheritance joint venture. On the one hand, he developed the V-2 rockets for nazi Germany during the World War II. On the other hand, his ideas, rejected as not plausible at that time (when presented them as part of its allegations of doctoral), had opened the way for the development of the rockets and later helped up-to-the-minute in the United States of America in space.

Her Youth

Hermann Oberth Julius was born in June 25 1894, from parents speakers of German and Romanian from Transilvania (a province in Romania). Inspired by the novel science fiction of Jules Verne, “from earth to moon”, Oberth leans early to study mathematics, of which he knew that finally he need. At the age of 14 years, Oberth has designed the concept of a rocket back down, which would be the use of exhaust gas expelled to propel.

The son of a doctor, Oberth has participated at the University of Munich, in 1912 to study medicine. During the first world war, he served as a doctor in the army Austro-Hungarian occupation, where he quickly realized that he did not want to be a doctor. In 1917, he suggested the development of missiles long range of action with the liquid fuel for the German army, which has immediately rejected the idea. He studied, also, the feasibility of a rocket with several steps to the waiver gears who were useless.

Oberth married Mathilde Hummel on 6 July 1918. The couple has had four children, two of whom were killed during the second world war.

The Theory of the Missile Dismissed

At the end of the first world war, Oberth returned to Germany to participate at the University of Heidelberg, studying physical, rather than medicine. In 1922, he presented dissertation based on a design by the missile. It has been rejected by the scientists gophers then.

It fiercely, he has published his theories as a pamphlet entitled “Die Rakete zu den Planetenräumen” (“by missile in space planetary drive”), which has extended it subsequently at 429 pages. The work not only of the mathematical demonstrated the ability of a rocket leaving the orbiting the earth, but also explored the theory that finally they will be able to operate in a vacuum, where they would be able to travel even faster than their own exhaust (When Robert Goddard has proposed in an independent manner, the idea that a missile would be able to maintain the tractive force in a vacuum in the year 1920, he was faced with a public ridiculing.).

Oberth also has reached the problems with respect to the potential effects of the traveling in the space on the human body, as well as the ability to launch satellites orbit.

The work of the Oberth have attracted a lot of attention from the community of missiles, inspiring a young Werhner von Braun to apply in math and physics in order to better understand the equations. A few years later von Braun introduced Oberth in the “German Space Travel Society”, where later Oberth become the president.
