  • Countermass liquid for a shoulder launched munition propulsion system
    Patent number: 11035631
    Abstract: A countermass liquid for a shoulder launched propulsion system that has low corrosivity, high density, low viscosity, and a constant viscosity as a function of temperature. Upon function of the shoulder launched propulsion system, the countermass liquid may be expelled through the breach end of the shoulder launched propulsion system by expanding propellant gas. The countermass liquid may be an organic salt selected from the group consisting of at least one or more of cesium formate and potassium formate.
    Type: Grant
    Filed: February 27, 2017
    Date of Patent: June 15, 2021
    Assignee: Nammo Defense Systems Inc.
    Inventors: Dominic Jezierski, Jerry Lambert, Harry Blomquist, Stephen Joseph Early, Bill Goodwin
  • Countermass propulsion system
    Patent number: 10488127
    Abstract: The invention relates to a countermass propulsion system for shoulder-launched munitions, recoilless rifles, rockets and similar class weapon systems, fired from an enclosure and utilizing a Davis Gun propulsion system by accelerating a projectile in one direction and a countermass in the opposing direction to minimize recoil, light signature and acoustic signature of the weapon system.
