[Aluminum Road Network] Not long ago, NASA released a very avant-garde and highly technological future aerospace vehicle propulsion system. The system was led by the NASA sub-unit Marshall Space Center, which is called the solar wind. The Heliopause Electrostatic Rapid Transit System is referred to as the solar electronic sail propulsion system HERTS. Is it because of the sense of future technology? Did you overturn your understanding of the aircraft? Electronic sail structure composition Electronic sails are not as complete as the sails in the traditional sense. As the main part of the propulsion system are some particularly elongated aluminum wires. Yes, you read it right. Those slender lines are aluminum lines. Of course this is not the common aluminum wire in our lives. These aluminum wires are very thin and extremely long, 1 mm in diameter, roughly the same thickness as a paper clip, and it is extremely long. It is 12.5 miles, which is about 20 kilometers. What is the concept of this length? Almost 219 football fields lined up together. An electronic sail will generally consist of 10-20 aluminum lines that diverge radially from the center. After the rocket arrived at the designated position, the aluminum wire was stretched from the center to both ends, and two small rockets were used to complete the fan-shaped deployment of the aluminum wire group. Let the electronic sail complete the final deployment. Electronic sail power source Of course, not having such an electronic sail propulsion system can sail in space. The important thing in interplanetary navigation is to promote power. Traditional aerospace engines are required to have their own propellant, which will occupy a large proportion of the total rocket mass, severely restricting the spacecraft payload and flight distance. Therefore, the search for more effective ways of advancement has always been the direction of scientific research. The scientists turned their gaze to the sun, the ultimate energy boss in this solar system. Electronic sails use the sun's solar wind to advance. Different from the wind composed of molecules on the Earth, the solar wind is a supersonic plasma charged particle stream emitted by the upper atmosphere of the sun. It is composed of particles such as protons and electrons, and the effect produced when they flow is very similar to the flow of air. The density of the solar wind is very thin and insignificant. Generally, there are several to several tens of particles per cubic centimeter in the interplanetary space near the Earth, and the density of the earth's wind is 2687 billion per cubic centimeter. molecular. However, the violent wind from the solar wind is far more than the wind on the earth. The speed of the solar wind near the earth is generally 350-450 kilometers per second, and 800 kilometers per second when strong. There may be no sense in just looking at the numbers. To know that the violent wind on the earth is a typhoon, the wind speed of Tier 12 is only 32.5 meters per second, and this kind of wind speed is already a disaster. Due to the thinness of the solar wind, we do not have any direct perception of it. However, its super high speed is the key to the electronic technology. In fact, some scientists had previously tried to fly through the solar wind. NASA successfully launched a small solar sail power satellite in 2010. In May of the same year, the Japan Space Agency’s space probe named IKAROS was launched to prove the possibility of solar sails being used for interplanetary navigation. Unlike the previous solar sails, which used sail-effect ultra-thin metal plates and depended on solar light pressure, the e-sail project used the above-mentioned single-strand aluminum wire. These aluminum wires will be positively charged and use the force repelling the particles in the solar wind to provide power for spacecraft and aircraft. In theory, it does not require any propellant. As long as there is sunlight, it can fly, and it can fly far faster than existing aircraft. It is expected that the high speed can reach 400-750 kilometers per second. Electronic sail high speed movement In order to better understand e-sail, you need to introduce a new unit. The astronomical unit AU is commonly used in astronomy instead of the unit of length we commonly use to express distance. An AU refers to the average distance from the sun to the earth, about 149.6 million kilometers. Because the solar wind becomes thinner and thinner away from the sun, in order to ensure sufficient thrust and acceleration, the effective area of ​​the electronic sail will increase with the voyage. At 1 AU, the effective area is 601 square kilometers, which is only slightly smaller than in Chicago; and when it reaches 5 AU, the effective area is 1200 square kilometers, which is close to the size of Los Angeles. Another advantage of the electronic sail is that it accelerates far beyond the solar sail. Normally, the solar sail passes 5 AU, and its acceleration will stop due to the dissipation of the solar photon energy. Due to the continued particle flow and increased effective area, the acceleration of the electronic sail will not stop but will continue to a distance of 16-20 AU. As the first human aircraft to reach the edge of the solar system, the 2010 Voyager completed its mission 35 years later. The e-sail can accomplish this task in 12 years or less. Therefore, this black technology may subvert the existing propulsion technology. Of course, this technology did not enter the launch phase. The number of protons that had been deflected by wire repulsion and the number of electrons attracted to the wire were still being tested at the Marshall Space Flight Center. Plasma testing was also in progress to correct the model. It is expected that within 10 years, the electronic sail can formally enter the space stage. Actually, no matter what the future of e-fans is, the future of humans in aerospace will surely break through the explosion of existing technology, and our pace in space will be further and further. Only breakthrough ideas will bring breakthrough technologies. bidet faucet,bidet faucets,bidet taps,bidet mixer tap Guangdong Kinen Sanitary Ware Industrial Co.,Ltd. , https://www.kinengroup.com
