Cross border artifact in the aerospace industry

According to reports, the launch vehicle of China's suborbital reusable demonstration verification project was ignited and took off on time at the Jiuquan Satellite Launch Center on July 16th. After flying according to the set program, it landed smoothly and horizontally at the Alxa Right Banner Airport, and the maiden mission was a complete success.

At present, major space powers are intensifying the development of spacecraft that can freely enter and exit space, return as needed, and be reusable. So, what aerospace vehicles are countries around the world developing? What are the application values of aerospace vehicles?

Aerospace vehicles refer to reusable space transportation systems that can fly back and forth in dense atmospheres, near space, and orbital space.This aircraft combines aviation and aerospace technology, meeting both civilian transportation needs and military missions. It has typical characteristics of free access to space, on-demand return to the ground, and reusability. It has become a key factor in future large-scale space development and ensuring space superiority, and is increasingly valued by countries around the world.In order to quickly and freely enter and exit space, and seize space resources, the world's aerospace powers have successively developed disposable launch vehicles, space shuttles, reusable launch vehicles, and today's spacecrafts.

In military terms, aerospace vehicles can serve as reconnaissance, surveillance, and early warning platforms, space weapon launch platforms, rapid long-distance transportation systems, and can also be used for anti satellite operations, serving as wartime space reserve command posts.After transforming into an aerospace bomber carrying weapons, the combat area of the spacecraft will cover the entire Earth and even near Earth space, achieving a one hour global coverage. If deployed in space for a long time, it can strike enemy satellites, spacecraft, and even space stations.

As a cross-border product of the two high-tech fields of aerospace, spacecraft still face enormous technological challenges. The integrated design technology of aerodynamic shape and structure, combined power mode conversion and matching technology, ultra-high temperature thermal protection technology, energy management technology, wide range high dynamic strong coupling flight control technology, ground and flight test technology are all technical difficulties facing countries around the world.

Aerospace vehicles have gathered a large number of forward-looking and pioneering high-tech innovations, which not only promote the development of aerospace power, aircraft design, optoelectronic devices, advanced materials and manufacturing, but also play a significant leading role in the development of weapons and equipment. With the increasing maturity of various key technologies, aerospace vehicles are sparking a new research boom that deserves high attention from all countries.
