Not long ago, the first large-scale solar rainbow drone independently researched and developed by China successfully completed the flight test of the adjacent airspace of 20,000 meters. The success of this test indicates that China has become the third country to master this technology after the United States and Britain. At the same time, it also marks that China's drone technology has reached the world's advanced level.
In the past few years, drone technology has developed rapidly. Civil drones have penetrated into the life of scientific research, medical care , education and other people. Military drones are widely used in aerial reconnaissance, surveillance, communications, anti-submarine, and electronic. Interference and other fields, especially in the adjacent space, because solar powered drones have super long voyages (powered by sunlight, in principle, not limited to navigation), high altitude, high cost performance, and other traditional aircraft and spacecraft Advantages and favors. But the only countries that can truly control this technology are China, the United States and Britain. Therefore, the ability to control the adjacent space flight technology has become an important indicator for measuring the level of drone technology.
So what is the adjacent space? What is the military significance of conquering this field?
NearSpace is a universal term for the US military's range of 20 to 100 kilometers above sea level. It is an academic concept with no internationally accepted exact definition. The US military is also known as the "cross-cut zone." The "Asia-Pacific space", "ultra-high altitude" and "high altitude" spoken by Chinese academic circles also refer to this region. Adjacent space, the air space below it is often called "sky", which is the main activity space of traditional aircraft; the airspace above it is the usual "space", which is the space for spacecraft.
