Spaceship not limited by transportation requirement fuel with you – that’s what the authors of the next promise miracle engine. Moreover, they proclaim that working samples of such an installation have already been created and are underway experiments. You cannot make a rocket that moves something forward, while not moving something back, suggests us the third law of Mr. Newton and life experience. But it seems in Chinese, both speak not so clearly. And exactly therefore, in the Middle Kingdom they built their version of the magnetron according to the scheme Roger Shawyer And the impulse in it, as we are assured, created despite the fact that no mass is ejected in the direction opposite to movement, and even no energy theoretically must leave the system. If all this is true, then the engine, not requiring emissions of fuel consumed, can work unlimited time until on-board systems run out of energy. By the way, in the solar system, and even close to the luminary, it billions of years. Is everything we saved? In general, we are talking about another a session of magic, and you are undoubtedly preparing to expose it, not is not it? Alas, we will not justify your hopes – after all, exposing yields only something undoubtedly demonstrated. However, tell the story from the start. In the 1950s, Allen Cullen (Allen Cullen), Electrical Engineer at University College London (UK), suggested that you can create a magnetron with resonant cavity of such a shape that the pressure of microwaves per its part will be higher than the other. Hearing this, Newton, undoubtedly turns over in the coffin, believing that he hallucinations, for the sum of pulses from photons in a chamber of any shape should be zero.

Then the British engineer Roger Sawyer suggested that if the magnetron resonator will be a truncated cone (asymmetric), relativistic effects will make it possible to get less pressure than based on. Microwave group speed he postulates, depends on the diameter of the resonator – and therefore, where the diameter is smaller, the pressure of the microwaves will be higher. Moreover, at resonator and microwaves will be different reference systems, I’m sure inventor, so the system will be open. And the law of conservation impulse is not violated, since the moment received by the engine, equal to the moment lost by microwaves in the resonator. True in his interpretation of this engine is not capable of infinite acceleration. By as the acceleration increases in the direction of the vector of its momentum, thrust falls, and at a significant speed the hypothetical space apparatus further acceleration in the same direction becomes impossible (maneuvering and so on). The scientific community believes that the so-called inertoid is “invented” – a device supposedly capable of translating in space without interactions with the environment, due to only one the movement of the working fluid (microwaves) inside itself. Well, that’s all we remember too well how in 2008 from the Plesetsk cosmodrome Rocket rocket launched into space a small spacecraft “Jubilee” – with our own (thorough, homespun-woven) inercoid on board. Naturally, nothing decent but loud scandal, from the “gravitsapy in Russian” did not work. But ridiculous Russians Mr. Sawyer is not a decree, he persists: EmDrive does not violate anything, because for the walls of the magnetron cavity and for microwaves different reference systems; in other words, the system does not is closed. Well, and, of course, experiments, where without them:
We repeat: in our opinion, all these are typical schemes in principle idle cars. And from the video does not follow that this the emdrive sample really has nothing but a magnetron and resonator, that is, experience is unconvincing. In due time, the unit Boeing, known as Phantom Works, looked at a similar machine, but he was smart enough not to spend money on working under this scheme. And already if Phantom Works didn’t pick up some crazy idea, it means too crazy even by the standards of this very addicted structure.

One of the first samples, according to Mr. Sawyer, is superior thrust ion engine SMART-1 and does not need xenon.
One of the first samples, according to Mr. Sawyer, is superior thrust ion engine SMART-1 and does not need xenon. Still, a group of Professor Yang Juan from Northwestern Polytechnic University (PRC) published in Acta Physica Sinica is a work that claims the opposite. IN her experiment EmDrive version can give impetus to 180-750 mN with an input thermal power of up to 2,500 watts. Other in words, a magnetron equal in power to a conventional microwave (also equipped with magnetrons) gives more traction than standard ion NASA engine, while also consuming expensive xenon. If it seems to you that 750 mN is still small, think again. At superconductor resonator, according to Roger Sawyer, traction should be equal to three tons per kilowatt of input energy (i.e. up to flying cars). What can I say to this … Theories where preservation law is allegedly violated impulse, for some reason, is poorly perceived by modern science. Not, we do not call for the burning of witches, but to this day all the experience of humanity proved the validity of the mentioned postulate. The only thing that can finally resolve the issue is practice. That is, a detailed description of the experiment (which in the work of the Chinese no), with its subsequent reproduction by third-party laboratories from other countries. In the meantime, the phrase “Chinese science” has as negative connotations in the scientific world as ten years back phrase “Chinese quality” in mechanical engineering. IN in general, the experimenters from China failed to convince us of the point of view Mr. Sawyer. Study report published in Acta Journal Physica Sinica, and its preprint can be found here.
