The "EmDrive" proposed for many years is called the "impossible engine", and some people think that it will send humans to Mars within 10 weeks, but few people can clearly explain what it is. How it works. Now, this kind of engine that only uses solar energy to provide thrust through the rebound of microwaves in enclosed chambers has been upgraded. Roger Shawyer, the inventor of the engine and British scientist Roger Shawyer, has drafted a new patent report and introduced a new version of the EmDrive engine, including a superconductor plate that can greatly increase thrust. An EmDrive engine prototype. Some people think that the engine will allow the aircraft to reach Mars in 10 weeks, but more people think that the system violates the laws of physics. The EmDrive engine technology is dubbed the "curvature engine" - derived from the mysterious engine of the "Star Trek" series. Roger Shawyer, the inventor of the engine and British scientist Roger Shawyer, has drafted a new patent report and introduced a new version of the EmDrive engine, including a superconductor plate that can greatly increase thrust. In the new design, this flat superconducting plate is located at one end of the engine and at the other end is a unique non-superconducting plate. The superconductor board will minimize Doppler shift and make the engine more powerful. The flat design also reduces the manufacturing cost of the superconductor. In many people's eyes, EmDrive's concept is too exaggerated, and its design is also contrary to the laws of physics. However, in August this year, a laboratory of NASA announced that they had conducted a study on the concept of EmDrive and was preparing to publish relevant research results in December. The concept of the EmDrive engine was proposed by Roger Sawyer in 2000. Since then, four independent laboratories (including NASA's laboratory) have made engine prototypes. However, this amazing engine still puzzles many scientists because it apparently violates the law of conservation of momentum. For example, when the rocket accelerates, it must have an equal force in the opposite direction - from the combustion of the rocket's internal combustion fuel. According to current information, the results of the upcoming publication of NASA's Eagleworks team will bring great shock to the physics community. A user of the Nasa Spaceflight Forum said: "My understanding is that the new paper of 'Eagle Factory' has now been received by a peer-reviewed journal and it will be published in this journal." Earlier this year, "Eagle Factory" A member of the team confirmed that they are working hard to complete the study. Papers on EmDrive are being peer-reviewed, but the process will be very slow. NASA's "Eagle Factory" Lab is dedicated to researching advanced advancement methods The researchers pointed out that the mutual interference of photons will make the overall effect look like nothing. This situation is like two waves of water moving together. At some point, the peak of one wave of water just overlaps with the wave of another wave, and they cancel each other out. The concept of the EmDrive engine is actually very simple. It is to provide thrust for the spacecraft through the microwave rebound in a closed container. In an article published earlier this year in the AIP Advances, researchers pointed out that EmDrive emits emissions as well as other rockets. "The working principle of EmDrive is the same as any other rocket," said Arto Annila, the first author of the paper and a professor of physics at the University of Helsinki in Finland. "The fuel is the photon input at the microwave wavelength. †The researchers pointed out that the mutual interference of photons will make the overall effect look like nothing. "In the engine compartment, the incoming photons bounce back and forth. Some of the photons will inevitably be completely interfered, and two photons that interfere with each other will undergo a 180-degree change in state," said Alto Anila. In the case of complete interference, the electromagnetic field of the two photons will disappear and they will continue to move themselves." This situation is like two waves of water moving together. At some point, the peak of one wave of water just overlaps with the wave of another wave, and they cancel each other out. The water will not disappear, it is still there. By the same token, this photon still exists and carries momentum, but they can no longer be regarded as light waves. “This photon without a net electromagnetic field escapes from the engine room,†Anila said. “The outflow of these paired photons is the emission of EmDrive. When the chamber shape is asymmetric, it is tapered, for example. Conical, the outflow of the pair of photons becomes non-uniform. Therefore, the momentum loss of these paired photons is also non-uniform. In other words, the thrust is not zero." The theory of Anila et al. shows that the reaction thrust generated by EmDrive exists but cannot be seen. Anila said that these photons could theoretically be detected with interferometers, the instruments used to detect gravitational waves. "My instinct is that detecting such a tiny extra energy density would be very difficult, especially when stably operating EmDrive," he said. "But our theory of engine emissions will be useful in designing engine rooms. , It allows pairs of photons to flow out in a more appropriate direction, creating more thrust.†Solar Controller,Solar Charge Controller,Solar Intelligent Controller,Solar Tracker Controller Fuzhou Mei Li Cheng Imp&Exp Co., Ltd , https://www.mlc-solar.com
