German physicists have confirmed efficiency of "impossible" electromagnetic engine thrust Bashny.Net

German scientists confirmed , that "impossible" the engine on the basis of electromagnetic waves can indeed create a non-zero traction. The results of their study, they presented a July 27 conference , dedicated engines and power, which was held by the American Institute of Aeronautics and Astronautics. Represented work Professor Martin Tadzhmar from the Dresden University of Technology.

British citizen and engineer Roger Scheuer founded Satellite Propulsion Research Ltd in 2001 specifically to develop an electromagnetic motor (EmDrive) own design. The engineer had previously worked in the military industry, involved in space projects, including the development of a European global navigation system "Galileo".



Invented them the engine seemingly violates the law of conservation of momentum - it creates cravings because of the reflection of electromagnetic radiation from the walls of the chamber without reflection whatsoever jet ejection. Due to the uncertain nature of the engine it is not taken seriously for a long time, however, for health check eventually accepted by NASA - the agency with enough good reputation.

Tests were conducted last year , and on their results in the April 2014 Agency conference on engines confirmed that the engine, tested them, really create (albeit small, 30-50 mN) cravings. The absence of violations of the laws of physics engine creators explain that moving at near-light speed magnetic waves obey the service, so the waves and the camera are in different frames of reference.

Professor responsible for checking the Harold White , who presented his theoretical model of the engine. He believes that the acceleration of the system attached to the virtual particles that are born in the quantum vacuum and behave the same way as the working fluid in ion engines - only in this case, the working fluid is extracted from the "very fabric of space-time" that allows you not to drag him a.

The presentation of this year, Professor Martin Tadzhmar indicates that he spent with the team in the lab all the tests and confirmed the existence of a real thrust from the engine. At the same time, as an honest scientist points out, "the nature of the observed thrust is not yet clear."

As stated in the presentation: "We have observed thrust coincides with the predicted values, thus eliminating a lot of possible sources of error, which gives the basis for further research. The next step is to apply the improved magnetic insulation, the continuation of the tests in a vacuum, and the improved model with increased engine thrust indicators, and the use of electronic control that allows to configure the device to search for optimal operation ».



Do scientists have rewritten some ideas about the physical processes or the operation of this motor is understandable with the current scientific positions - time will tell. But reconfirmation enough reputable researchers give reason for cautious optimism.

Interest in the device is constantly increasing. If at first no one took seriously Scheuer, in particular, because of his lack of published scientific papers, but now it also has a scientific work, and confirm the feasibility of its offspring. The design of the device is much easier than, for example, the same ion engines, and is closer to the possibility of creating "in his garage."

On the topic of EmDrive has been filled with good Wikipedia (in English). In May 2015 Romanian engineer gathered EmDrive own and independent research conducted for this "bucket with a magnetron," as a result of which also received the validation of.





If we imagine for a moment that this engine will be equipped with a real interplanetary spacecraft, it will open up hitherto unseen opportunities to explore the solar system. The same flight to Pluto, who have won nine New Horions and a half years, can be performed with the engine type EmDrive 18 months . And it is only in view of the draft, which was obtained in the laboratory today. The secret is that this engine can accelerate constantly, and not just fly on a ballistic trajectory.
