Thanks to CTOnews.com netizen ZKSen for the clue delivery! CTOnews.com, July 20 (Xinhua)-- the 4-second electromagnetic ejection microgravity experimental device developed and built by the Space Application Engineering and Technology Center of the Chinese Academy of Sciences has been put into trial operation. The device uses electromagnetic ejection to build a microgravity experimental environment on the ground, and the relevant performance indicators reach the international advanced level.

▲ video from blogger @ Ghost Guzi Rabbit Master according to the introduction, the device has the following advantages:

In terms of experimental efficiency, the device can achieve the frequency of nearly 100 experiments a day.

In terms of the requirements of the experimental load strength, the electromagnetic driving force of the experimental cabin can be controlled in the whole process, the recovery acceleration of the experimental cabin can be controlled at about 3G, and conventional scientific instruments can be used in experiments.

In terms of operating cost, the device uses energy storage and electromagnetic drive technology, and the power consumption of a single experiment is only about 1 degree, which is convenient for large-scale scientific experiments.

This device uses an electromagnetic ejection system to vertically accelerate the experimental cabin to a predetermined speed and then releases it. The experimental module can provide a microgravity environment of 4 seconds and 10 μ g horizontally for scientific loads during the up and down stages. At the same time, the overload acceleration does not exceed 5 times gravity acceleration, and the experimental interval is no more than 10 minutes.

According to the installation Company of the second Bureau of China Construction, as a ground-based microgravity experimental facility, the project uses a linear motor to drive the experimental cabin, and the above drop mode creates a microgravity environment. By planning the motion process of the motor, it can simulate several modes such as microgravity, lunar gravity, Martian gravity and uniform motion, which can be used in the foundation microgravity experiment. It is the key technical verification project of the "kilometer well drop device". There is no relevant engineering experience for reference in China.

CTOnews.com inquired that this is the second electromagnetic ejection microgravity experimental device in the world after Germany. The Center for Space Application Engineering and Technology of the Chinese Academy of Sciences is planning to build a 20-second electromagnetic ejection microgravity experimental device, Xinhua reported.
