  • Patent number: 10527380
    Abstract: The muzzle brake attaches to a distal end of the barrel of a firearm, typically a handgun, either built into the firearm or as an accessory attachable to the firearm. The muzzle brake includes a propelling nozzle in the form of a central chamber aligned with proximal and distal openings aligned with a barrel of the firearm. This propelling nozzle extends upward, generally expanding in cross-section, to a rim where it opens above the firearm near a distal end of the barrel. The shape of the propelling nozzle (or series of nozzles) is preferably selected to optimize downward reactive force when expanding gases discharged from firearm discharge expand upward out of the propelling nozzle. A downward reactive force is thus created which counteracts recoil of the firearm.

  • Patent number: 10520278
    Abstract: A shockwave impulse disruptor system for use in an underwater firearm. The system includes a barrel having a bore, a muzzle, and at least one barrel port. A housing is external to the bore and defines at least a first gas expansion chamber. The expansion chamber is in fluid communication with the barrel port and has at least one exhaust port. The barrel bore and expansion chamber are flooded when underwater. Propellant gases that push a projectile through the bore are vented through the barrel port to force water from the expansion chamber through the exhaust port and to vent propellant gases. This delays the release of gases to surrounding water and reduces the amount of gas expelled through the muzzle.

  • Patent number: 10520272
    Abstract: Openings in a muzzle brake provide recoil inhibition and impulse noise attenuation by redirecting the propellant gases to the external environment. A turning vane aggressively turns and redirects the propellant gases in a rearward direction to counter the recoil of the weapon system. An angled baffle provides a physical barrier to redirect propellant gases rearward to provide additional force to counteract the recoil force. Attenuation slits mitigate blast overpressure by producing a fluid barrier of high velocity propellant gases directed radially away from the muzzle brake. The fluid barrier from the attenuation slits interacts with the redirected propellant gas from the turning vane and the angled baffle and redirects the counter recoil gases away from the crew.

  • Patent number: 10215543
    Abstract: A lightweight linear explosive disruption tool that may be used to fire a high speed projectile at a hazardous device in order to separate the components of the explosive train, thereby rendering it safe. The linear explosive disruption tool utilizes open cellular foam materials to prevent collateral damage of explosive gases and fragmentation that would otherwise prevent the device from being fired from a robot. An internal clapper tube distributes forces to the ligaments of cellular foam material and an external support tube contains the explosive fragmentation and blast overpressure. An internal barrel provides projectile travel in a single precision oriented direction and also reduces recoil which also enables the device to be fired from a robot as well. Such a tool prevents explosive gases and fragmentation from causing unnecessary collateral damage to the surroundings or supporting robot with reduced recoil effects.
