China Launches World’s Most Powerful
On Monday, China unveiled the most powerful centrifuge in the world, capable of generating forces 300 times stronger than Earth’s gravity and handling payloads up to 20 tons. Indeed, this groundbreaking machine marks a new era in high-gravity research and material science. Moreover, it opens possibilities for experiments previously impossible in traditional laboratories.
CHIEF1300: The World’s Strongest Centrifuge
The CHIEF1300 is part of the Comprehensive High-Gravity and Multi-Disciplinary Experiment Facility (CHIEF), currently under construction in Hangzhou, Zhejiang Province, eastern China. Furthermore, the facility aims to support a wide range of cutting-edge research fields, including:
- Resource extraction from deep oceans and the Earth’s crust.
- Disaster prevention and mitigation, including underground waste disposal.
- Synthesis of advanced materials.
Additionally, Zhejiang University developed the CHIEF rocket, integrating three centrifuges and 18 flight devices, supporting six experimental cabins. Two additional centrifuges with larger capacities are under construction to expand research potential.
What is Hypergravity?
Hypergravity refers to any gravitational force exceeding that on Earth’s surface. For comparison, a rollercoaster rider briefly experiences about twice Earth’s gravity. Meanwhile, astronauts endure forces over 5G during launch. In contrast, the CHIEF centrifuge is designed to sustain accelerations of up to 1500G, demonstrating the extreme capabilities of this facility.
Chen Yunmin, chief scientist at Zhejiang University, explained: “In hypergravity research, scientists can simulate real-world hydrogeological disasters. Moreover, geological evolution and extreme environments can be modeled on a laboratory scale within a practical timeframe.”
CHIEF as a Geomechanical Simulator
Under extreme conditions, CHIEF functions as a geomechanical compressor. For instance, a 1-meter-scale model at 100G can replicate events that occur on a 100-meter scale in reality. Consequently, pollutant cloud dispersion that would naturally take a century can be reproduced in just 3.65 days in the lab.
CHIEF1300 Structure and Operation
The CHIEF1300 resides in a 230-square-meter circular underground hall. A giant 6.4-meter-radius arm spins at high speeds to generate immense centrifugal forces. Indeed, the faster it rotates, the stronger the hypergravity produced.
Ling Da Sheng, lead engineer at Zhejiang University, said: “CHIEF1300 is installed below ground level and equipped with vacuum cooling systems and protective walls to mitigate harmful effects from air resistance and machine heating.”
Experimental Achievements
Initial tests have already yielded remarkable results. For example, researchers simulated powerful earthquakes to verify the seismic performance of hydroelectric dam foundations. In addition, they quantified the effects of 4-meter-high waves and 20-meter tsunamis on seabeds to guide offshore wind farm planning.
Furthermore, CHIEF replicated sea pressure at depths of 2,000 meters to evaluate methane hydrate extraction safety. Additionally, high-strength, low-defect metal alloys were produced, highlighting its capabilities in advanced material science.
CHIEF as an Open Research Hub
Chen emphasized that the facility will operate as an open, collaborative center for pioneering science. Moreover, it aims to cooperate with top research teams worldwide to accelerate discoveries and drive innovation in multiple disciplines.

Conclusion
The launch of China’s CHIEF1300 marks a milestone in experimental science. Indeed, this world-leading centrifuge enables studies previously impossible, bridging extreme hypergravity research with real-world applications. Moreover, it positions China as a global leader in high-gravity experimentation, disaster modeling, and advanced materials development.
