Hong Kong's South China Morning Post reported that a Chinese scientist published a paper saying that there was a problem with the hypersonic simulation analysis software released by NASA. In the analysis of the supersonic flow field, there is a fatal flaw. If this software is used for analysis, it will not be possible to accurately estimate the chemical and temperature changes on the surface of the aircraft, which may lead to structural failure. After the publication of this paper, many people commented that the relationship between China and the United States is so bad that Chinese scientists should not be reminded that the United States has made such a big mistake in hypersonic research. If the US side improves its shortcomings, overcomes technical difficulties, and effectively improves the efficiency and effectiveness of hypersonic research, it will promote the research and development of hypersonic weapons in the US military, which will be detrimental to China.
Did NASA really make such a fatal mistake? It's not going to be that simple. Logically speaking, it is unreasonable for the U.S. government's scientific research institutions to put a strategic scientific research tool on the Internet and let everyone download it freely. It is said that this software is blocked in China and cannot be downloaded in China. But this blockade is useless, as long as you download the installation package in a non-sanctioned country and send it back home, you can get the software. Previously, there were also satellite orbit simulation software developed by some enterprises in the United States, which was once a commonly used tool in domestic aerospace research institutions and relevant colleges and universities. After the embargo by the United States, domestic scientific research institutions can no longer download and use. Therefore, it is impossible to ban Chinese scientists from obtaining this software by blocking Chinese mainland websites. So, is it possible that the United States is deliberately misleading scientific researchers all over the world by putting such advanced tools and software on the Internet?
That's probably the case. For many years, the substantive capabilities of global scientific research in the field of hypersonic have been concentrated in China, the United States and Russia, and other aerospace countries, including France, Japan, Germany, India, etc., are also very interested in the field of hypersonic technology, but these countries have not yet come up with practical models. The lack of supersonic flow field analysis capabilities is an important reason for this. So NASA's software may be inherently misleading. There is another case. The software provided by NASA is incomplete, and now we have all heard of a model called in-app payment, the basic version of the software is free for everyone to use, but if you want to get professional, high-end capabilities, you have to pay. This is the case with the satellite orbit design software in the United States. The basic version is also free, but there is a charge for plugins for different specific tasks.
Tools like hypersonic analysis software may also have some plugins that actually work, and when these plugins are integrated into the software platform, there may not be any problems that Chinese scientists have discovered. However, it is likely that such plugins are not for sale, and even their existence is kept secret and only available to agencies licensed by the U.S. government. Therefore, when Chinese scientists publish papers, they are certainly not reminded of American institutions, but of researchers from other countries who blindly trust the United States. After using American software, not only is it impossible to make a usable model, but it may even cause a huge resource consumption due to misdirection. If the computer used for the analysis is connected to the Internet, the software is likely to send the user's data back to the United States. It's actually not a secret, and we often see instructions on computer operating systems that some data is to be kept offshore. After the U.S. side gets the data and scientific research results of foreign scientists. You can sift out the creative and valuable parts from them, and get it for nothing.
The fact that Chinese scientists have debunked this also reflects our scientific research strength and level in the field of hypersonic speed. We have been able to identify, identify, and analyze the pitfalls that the United States has planted in its software. It is impossible to have this ability without a full understanding of hypersonic technology itself and simulation analysis software. Can these people, who always say that China is copying the United States in the field of high technology, be stopped?
