When targets move fast, artillery must be faster. 🤓 engineering
In August last year, the Yuma Proving Ground in Arizona added one more achievement under its belt, of firing a projectile from the Extended Range Cannon Artillery at the highest velocity ever on record, the U.S. Army said in aEven as we talk about ballistic missiles and rocket systems, artillery systems are cost-effective options that militaries have. Missions can be completed at a fraction of a cost when artillery is used, the press release said.
propulsion engineer with the Combat Capabilities Development Command-Armament Center was tasked to achieve this for the project. The charge, however, is inside the gun chamber when it is fired and invisible from outside when it is fired. The team, therefore, built a transparent ballistic simulator to enable visual observation of the firing. The BSIM bursts at low pressure, the press release said, but videos of the firing captured before the BSIM burst gave vital clues to understanding what was happening between the short interval where the gun was fired and the projectile left the barrel.
Looking at data related to the temperatures, turbulence, and speed of ignition inside the gun, the team of engineers tried to minimize the pressure waves and deliver a more controlled burning of the charge. The team carried out computer simulations with a variety of configurations to arrive at potential ones that could deliver a uniform burn and then tested them with the BSIM. Following this, the configuration was tested in the artillery gun.
