Recently, images, published by the state manufacturer of China South Industries Group (CSGC), have generated controversy among military experts. These are photographs of what would be the fastest coil canyon in the world. An electromagnetic coil cannon (a type of cannon that uses a succession of electromagnets to accelerate projectiles) developed by Chinese experts is able to shoot 3,000 shots per minutea speed that far exceeds traditional firearms and US commercial models.
While the CSGC maintained the secrecy on the technology involved, an article reviewed by pairs published in Journal of Gun Launch & Control by a team of military scientists offers a clue: This is the first electromagnetic coil cannon without condenser in the worldfed directly by lithium batteries. The advance focuses on the elimination of the Achilles heel of electromagnetic weapons: the capacitors.
The capacitors are devices that store electricity and, until now, the coil cannons depended on this for a quick download, a process that generates delay times for recharge. This limitation was an obstacle in the firing cadence of the first Chinese prototypes and the “anvil”, manufactured in the US, to 100 projectiles per minute.
The research team, led by Xiang Hongjun, professor at the University of Army Engineering, He completely omitted the capacitors and, instead, used lithium batteries sets to directly feed a multieapa coil system.
By eliminating the condenser load cycle, they exceeded the limit of the firing cadence, according to the authors. His tests reached 277 shots per minute, using only a 3D printed prototype. Thanks to China’s advances in semiconductor chips and thermal battery management, Practical applications have far exceeded experimental results.
The experimental rifle design has 20 stages of copper coil, each 25 mm long, arranged in a compact chassis inspired by the Belgian subfusil P90. When a steel, or armor projectile passes through a coil, the sensors activate power semiconductor chips with bipolar transistors of isolated door with precision of nanoseconds to send energy through the coil, generating magnetic fields that drive the projectile.
Fundamentally, the system uses position-temporization mapping algorithms to activate the coils only 2 mm before the projectile input and cut the energy 35 mm after its output, a balance that maximizes acceleration and minimizes inverse resistance. The key study innovations include security fuses to avoid battery overload During 750 A current peaks, simulations of finite elements that optimize the shots of the coil to milliseconds and heat dissipation systems that limit the increase in battery temperature.
As reported, the test model reaches a projectile speed that exceeds 300 km/h, ideal for the control of non -lethal disturbances, but scalable for lethal purposes, according to the study. More importantly, Its fire cadence of 3000 shots per minute, five times faster than that of an AK-47, allows an unprecedented suppression fire.
“Continuous high -speed fire deterrements that approximate and neutralizes enemy reactionswhich is ideal for disturbance control, ”says the study.
Other advantages include the absence of flash, silent functioning and adjustable lethality, which makes it ideal for covert missions. While it is revolutionary, technology faces obstacles such as a relatively low precision and a relatively long battery charge timewhich is currently about an hour, according to CSGS.
