China has improved hypersonic weapons using cheap American shi chip

Jetson TX2I chip, installed in the control system of hypersonic rectition air-reactive engine, increased the range and stability of the rocket flight. Scientists at the Beijing Research Institute of Energy Mechanical Engineering and the Dalyansky University of Dalyansky have been able to increase the efficiency of hypersonic weapons with artificial intelligence chip (AI), SCMP reports.

Researchers have used the Nvidia Jetson Tx2I graphic processor module in their work, which is available to any user. The speed of this module reaction made it ideal for optimizing the fuel supply system, diagnostics of malfunctions in hypersonic direct-current air-reactive engine (GPRD), which drives a hypersonic aircraft capable of developing speed in 7 makhs (8575 km/h. .

The Jetson TX2I testing showed that the calculations that have previously occupied seconds can now be performed in just 25 milliseconds. The team of scientists said that the Tx2I module in the GPRD management system has not only increased the range and stability of hypersonic apparatus during flight, but also significantly reduced the cost of their research and development. The American company NVIDIA began to sell TX2I for industrial use about 6 years ago.

The peak performance of the module with single accuracy is 1. 26 tflops, which is approximately one fifty of the capabilities of the most powerful Si-chip NVIDIA-H100. However, H100 costs tens of thousands of US dollars and is in a shortage, but TX2I can be purchased for several hundred dollars, it is not subject to export control of the United States and is widely available on the Internet.

Experts have previously believed that Shi-modules were able to perform only simple parallel calculations, and tasks such as modeling the field of hypersonic flow, when one event should occur before the other could be calculated, they could not. But scientists have found a way to solve the problem of sequential parallel computing, developing a new architecture of central and graphic processors. However, the engine is only one of the components of the entire weapons platform.

To apply the SI-chip to hypersonic systems, further work on the modeling of the air intake, shock wave correction and data modeling is required, developers believe. But it is unlikely that the American Chip TX2I will be implemented for Chinese hypersonic missiles. Processor manufacturers in the PRC can supply chips to the armed forces that work as much or even better than TX2I. It remains unclear why the researchers have chosen Nvidia for their experiment.
