2022 - 2024 美国帝国主义至少要持续颤抖三年！ The future of warfare: China says hypersonic missile tech years ahead of U.S. Chinese scientists claim to have developed hypersonic weapons with technical breakthroughs that the U.S. military may not even have until 2025. By Ian Miles Cheong | January 03, 2022 The future of warfare: China says hypersonic missile tech years ahead of U.S.South China Morning Post China says it has made breakthroughs in the precision and cooling mechanism of infrared sensors, enabling it to develop hypersonic missiles with heat-seeking technology, years ahead of the United States.
战争的未来：中共称 高超音速导弹技术领先美国数年 中国科学家声称已经开发出技术突破的高超音速武器，而美国军方 可能要到 2025 年才能拥有。 作者：Ian Miles Cheong | 2022 年 1 月 3 日 战争的未来：中国称高超音速导弹技术领先于美国南华早报数年 中国表示，它在红外传感器的精度和冷却机制方面取得了突破，使其能够开发具有热寻技术的高超音速导弹，比美国领先数年。 在南华早报的一份报告中，中国声称战争的未来可以被高超音速导弹改变，这种导弹能够根据热特征搜索、识别和锁定目标。 中国科学家声称已经开发出技术突破的高超音速武器，而美国军方可能要到 2025 年才能拥有。 中国的红外传感器技术可以使其武器以“前所未有的精度和速度”锁定几乎任何目标，包括隐形飞机、航空母舰，甚至街道上行驶的车辆。 南华早报报道： 第一代高超音速武器旨在穿透导弹防御系统并以五倍音速或更快的速度击中地面上的固定目标。虽然中国和俄罗斯都部署了一些高超音速导弹，但其他地方的流行观点是，除非一个国家想发动核战争，否则这些武器几乎没有实用价值。 但是，来自高超音速红外寻的计划的中国研究人员表示，常规战争可以通过高超音速导弹在空气较厚的低空飞行时根据其热特征搜索、识别和锁定目标来改变。在国防科技大学。 据该报报道，一名中国军事研究人员在2020年的一次学术会议上表示，如果美国的F-22导弹近距离发射或投掷炸弹，地空高超音速导弹可以在几秒钟内追上并干掉一架。 然而，高超音速热传感并非易事，为此，中国国内同行评审期刊《航空与航天》的首席科学家易世和教授表示，为此，中国取得了“一系列经试验证明有效的核心技术突破”。防御。 高超音速红外导弹已经通过测试，该工作为易的团队赢得了中国兵役技术奖。 “红外成像技术的精确制导是高超音速武器的力量倍增器，”易在论文中说。 “如果一方率先加工成熟的高超音速武器，那一方将在非对称攻击方面拥有绝对优势。” 南华早报报告补充说： 在高马赫数下，导弹表面会变得非常热，以至于目标的热信号可能会被背景噪声淹没。红外线窗口会破裂，因为没有任何玻璃材料可以承受极端的热量和冲击波。 来自世界各地的科学家提出了降低温度的方法，例如将液体溅到窗户上或在玻璃下安装冷却管。据易和他的同事说，这些想法中的大多数都无效或过于复杂。 中国科学家在红外窗前放置了一个吹气装置，以产生一层冷空气薄膜，减少玻璃上的热量。其他国家的一些研究团队曾尝试过这种方法，但失败了，因为冷却空气会引发强烈的湍流，从而扭曲热信号，使目标位置模糊、闪烁且不太准确。 易的团队通过多项突破解决了这个问题。他们开发了一种紧凑、轻便的设备，可以以超过声速三倍的速度产生极冷的惰性气体流，以减少信号失真。 他们设法将 40 个微涡流发生器挤入空气冷却装置中，以产生可以打破湍流的气流。他们还开发了一种新的数学模型，帮助他们更好地预测和消除导弹加速并以大攻角瞄准目标时的光学畸变。 美国曾经是热传感技术的世界领先者。 在 1980 年代和 90 年代，美国政府和军方在高速红外技术上投入了大量资金，用于开发该国的终端高空区域防御 (THAAD) 系统。但是，该技术仅适用于高海拔的稀薄空气。 为此，DARPA 已要求洛克希德马丁和通用电气等美国国防承包商开发用于高超音速导弹的红外传感器——但该技术的开发估计至少需要四年时间，使美国落后于中国同行。 In a report on the South China Morning Post, China claims that the future of warfare could be transformed by hypersonic missiles that are able to search for, identify and lock onto targets based on their heat signature. The Chinese scientists claim to have developed hypersonic weapons with technical breakthroughs that the U.S. military may not even have until 2025. China’s infrared sensor technology could enable its weapons to home in on almost any target, including stealth aircraft, aircraft carriers and even moving vehicles on the street with “unprecedented accuracy and speed.” SCMP reported: The first generation of hypersonic weapons were designed to penetrate missile defence systems and hit fixed targets on the ground at five times the speed of sound or faster. Although China and Russia had deployed some hypersonic missiles, a popular opinion elsewhere was that these weapons had little practical value unless a country wanted to start a nuclear war. But conventional warfare could be transformed by a hypersonic missile being able to search for, identify and lock on to a target based on its heat signature when flying at low altitudes where the air is thicker, said the Chinese researchers, from the hypersonic infrared homing programme at the National University of Defence Technology. According to the newspaper, a Chinese military researcher said at an academic conference in 2020 that a ground to air hypersonic missile could catch up with and take out a U.S. F-22 within seconds if it fired a missile or dropped a bomb close-range. However, heat-sensing at hypersonic speed is not easy, to that end, China has made a “series of core technology breakthroughs that were proven effective in tests” according to lead scientist professor Yi Shihe in China’s domestic peer-reviewed journal Air and Space Defence. The hypersonic infrared missiles have already been tested, and the work has won Yi’s team a Chinese military service technology award. “Precision guidance with infrared imaging technology is a force multiplier for hypersonic weapons,” Yi said in the paper. “If one party takes the lead in processing mature hypersonic weapons, this party will have the absolute advantage of asymmetric attacks.” The SCMP report added: At high Mach numbers, the surface of a missile becomes so hot that a target’s heat signal can be overwhelmed by background noise. The infrared window would crack because no glass material could withstand the extreme heat and shock waves. Scientists from around the world had proposed ways to lower the temperature, such as splashing liquid over the window or planting cooling tubes under the glass. Most of these ideas were ineffective or too complex, according to Yi and his colleagues. The Chinese scientists put an air-blowing device in front of the infrared window to generate a thin membrane of cold air, reducing the heat on the glass. Some research teams in other countries had tried this approach but failed because the cooling air could trigger strong turbulence that distorted the heat signal, giving a fuzzy, flickering and less accurate location of the target. Yi’s team solved this problem with a number of breakthroughs. They developed a compact, lightweight device that could generate an extremely cold stream of inert gas at more than three times the speed of sound to reduce signal distortion. They managed to squeeze 40 microvortex generators into the air-cooling device to produce air flows that could break apart the turbulence. They also developed a new mathematical model that helped them to better predict and eliminate the optical distortion as missiles accelerated and homed in on targets at wide attack angles. The United States used to be the world leader in heat sensing technology. In the 1980s and ‘90s, the U.S. government and military invested massive amounts of money into high-speed infrared technology used to develop the country’s Terminal High Altitude Area Defence (THAAD) system. However, the technology only works in thin air at high altitudes. To that end, DARPA has asked U.S. defence contractors like Lockheed Martin and General Electric to develop infrared sensors for hypersonic missiles — but development of the technology is estimated to take at least four years, placing the U.S. years behind its Chinese counterparts. https://www.rebelnews.com/the_future_of_warfare_china_says_hypersonic_missile_tech_years_ahead_us
