China's Tengyun Project: Pioneering Hypersonic Aerospace Innovations for Future Space Exploration
Since 2016, Chinese scientists have been diligently pursuing the Tengyun project, aiming for a significant breakthrough. This project involves creating an electromagnetic rail gun to propel hypersonic aircraft to speeds nearly reaching Mach 1.6, far surpassing the speed of sound.
These aircraft, expected to exceed the size of a Boeing 737, would autonomously form their track upon launch and proceed into space under their engine propulsion. The successful execution of this endeavor could substantially reduce launch costs, attracting attention from prestigious organizations such as NASA and SpaceX.
Challenges associated with relying solely on aircraft propulsion for liftoff, including fuel consumption and hazards during low-speed takeoff, prompted Chinese engineers to adapt the aerodynamic design and engine layout.
Despite compromises affecting the efficiency of high-speed flight, scientists remain optimistic about resolving these concerns. Lead scientist Li Shaowei emphasizes the potential of electromagnetic launch technology in overcoming these obstacles, highlighting its strategic importance in global technological advancements.
To validate their hypotheses, the China Aerospace Science and Industry Corporation (CASIC) plans to utilize the Datong test facility, originally designed for low-vacuum tube magnetic levitation train testing. This facility, repurposed for aerospace experiments, possesses the capability to propel hefty objects at speeds reaching 621 mph (1,000 kph).
Future plans involve expanding the facility to 37.2 miles (60 kph) to achieve maximum speeds of 3107 mph (5,000 kph), exemplifying the nation's commitment to pioneering aerospace innovations.
The collaboration between Chinese scientists and engineers underscores the nation's dedication to advancing aerospace technology. By pushing the boundaries of innovation, China seeks to establish itself as a leader in space exploration and travel. The ambitious goals of the Tengyun project demonstrate China's determination to explore new frontiers and revolutionize space travel on a global scale.

Funding Halts NASA's Electromagnetic Space Launch Attempt
China is delving into electromagnetic space launch systems, a concept previously explored by other space agencies like NASA in the 1990s. Despite NASA's attempts, financial and technical challenges led to project abandonment.
Similarly, the US military encountered challenges with lower-speed electromagnetic catapults intended for launching planes from aircraft carriers, particularly with an early version deployed on the carrier USS Ford.
Despite setbacks experienced by the US military, China remains committed to its pursuit. While the US has shifted focus towards hypersonic missiles, China persists in its endeavors. Tests have revealed the necessity of accelerating aircraft to extremely high speeds to eliminate the need for a rocket's initial stage. Moreover, the precise timing of aircraft release poses difficulties due to colliding shockwaves.
Nevertheless, scientists affirm the technical feasibility and safety of the concept for astronauts. China's significant investments in maglev technologies also provide it with a strategic advantage. However, uncertainties persist regarding whether the project will materialize and succeed in launching astronauts into orbit.
