One of the many sci-fi Space Travels Can Be Fictional

In Poul Anderson’s 1970 novel Number Zero, sailors want to go to the star of Beta Virginis and hope to rule the new world. The control of the ship is “Bussard ramjet,“a real (even fictional) method of advertising provided by a physicist Robert W. Bussard only ten years earlier. Now, astronomers have observed this strange process of interstellar travel new paper published in the magazine Acta Astronautica, and unfortunately, they have found a missing ramjet. It is possible from a good physical point of view, but the technical problems associated with it are insurmountable, the authors concluded.

Ramjet is actually a jet engine that “breathes” air. The best analogy of key machines is that it uses engine shifts to compress airflow without the need for compressors, making ramjet engines lighter and easier than their other turbojets. French explorer Rene Lorin received permission in 1913 for his idea for a ramjet (aka, flying stovepipe), although he failed to make a possible drawing. Two years later, Albert Fonó arranged for a ramjet pilot team to upgrade the ammunition, and it was finally granted to him in Germany in 1932.

The original Ramjet consists of three components: a vent, a ignition switch, and a nozzle. Hot smoke from oil burns through the nostrils. The combustion rate must be greater than the nozzle output speed to maintain proper flow, which the ramjet engine gains by “running” the outside air in the combustor and the forward speed of any motor-driven vehicle. There is no need to carry air in the boat. The downside is that the ramjets can only be fired if the car is already moving, which is why they need to take off with the help of rockets. As a result, ramjets are very useful as a chase, such as ramjet-powered missiles or to increase the amount of ammunition.

Robert Bussard thought that the idea could be changed as a way to promote astrology. The starting point is explained in his 1960 paper and pick up interstellar protons (ionized hydrogen) using larger ones magnetic fields as a “male face.” The protons are compressed until they form thermonuclear fusion, and the magnetic field converts the energy into rocket smoke to generate energy. When the train is moving fast, the proton speeds up, and its power increases.

But then scientists discovered that in the outer atmosphere of our solar system, there is a very small amount of hydrogen in the atmosphere. That’s why, in a 1969 paper, John F. Fishback proposed a magnetic field that works, taking into account factors such as radiation loss and interstellar emission.

In particular, Fishback calculated what the cutoff speed might be. “When the train is running too fast, the magnetic field rises sharply which points in the fusion reactor,” the authors of a recent paper explained. “Powerful field[s] Fishback said that the mid-star ramjet only accelerated to a certain speed, so it had to go backwards, for fear the magnetic field would reach the surface.

That is the answer to Fishback reviewed in a recent paper. “The idea is worth exploring,” he said. said co-author Peter Schattschneider, a Science fiction author and scientist at Vienna University of Technology (TU Wien). “The starry atmosphere contains highly soluble compounds, mainly hydrogen — about one atom per cubic centimeter. maneuvering the connector and speeding up the ship. “
