Chinese Smart Projectile Survives Extreme Conditions in Rail Gun Test

Inside a metal shell being hurled from a standstill to a speed many times faster than sound, the pressure could be as high as an elephant standing on every square inch of a human body. To make matters worse, an invisible, violent magnetic storm is raging through its path. A breakthrough, published in the Journal of North University of China (NUC) in May, has just told the world that the nightmare is now over. In a real-life firing test, a Chinese smart projectile prototype not only survived this journey but also recorded the entire ride. “The electromagnetic rail gun experiment verified that it can survive an extreme environment of an 8 ms pulse width, 20,000g-force overload, and a 7 T magnetic flux density,” wrote the team led by associate professor Ge Shuangchao with NUC.
