Supercavitating Firearm Tungsten Projectile Design (Small Arms or Cannon)
EXECUTIVE SUMMARY: The VA-111 Shkval torpedo and its descendants are supercavitating torpedoes originally developed by the Soviet Union. They are capable of speeds in excess of 230 mph. Modern torpedoes have three design features that allow them to move through water at high speeds: 1) specially shaped nose (cavitator) that initiates the supercavitation gas bubble, 2) a gas generator to maintain the gas bubble and 3) a…
Downsize and Lighten the M2 Machinegun to .408 Caliber. A White Paper.
Executive Summary: My design, the .408 CheyTac® cartridge, ballistically outperforms the .50 BMG in kinetic energy past 400 yards. My armor piercing design in the .408 caliber ballistically outperforms the .50 BMG armor piercing — AP (both silver and black tip) using 1-inch armor steel at 100 yards as a benchmark while maintaining Sub MOA out to 600 yards. The…
RiderSabot™ Unit: Sabot-Projectile, With or Without Penetrators that will Defeat Hardened or Armored Targets
Executive Summary: The term sabot is a French term meaning hollow shoe. However, in the science of Ballistics, the term sabot mean a device which ensures that a sub-caliber projectile remains in the center as it travels down a larger caliber barrel. After the projectile leaves the muzzle, the sabot falls away from the projectile1. The new invention is called…
Delayed Projectile Release Increases Muzzle Velocity: A New Design
Executive Summary: A new modification to centerfire cartridge cases delays the release of the projectile from the cartridge case. This delay increases the rate of travel down the barrel and in turn, elevates muzzle velocity. There is no increase in chamber pressure. External ballistics of these projectiles have a flatter trajectory, shorter time to target and increased deposition of kinetic…
Balance Flight Gen 2: Multi-Caliber Projectile Design for Extreme Long-Range Distances
EXECUTIVE SUMMARY: A review of rotating projectiles in flight (External Ballistics) is described. Next the physics behind Balance Flight design (Generation One) which is critical for accuracy at extreme long-range distances is reviewed. This is best exemplified by the .375 & .408 CheyTac® calibers. The focus of this article is to extend Balance Flight, Gen 1 to the next generation,…
