Patent number: 11536548Abstract: A projectile enables axial assembly and precise angular alignment of cylindrical or ogival sections of the projectile without interfering with internal parts spanning those sections. The projectile includes a turnbuckle design that minimizes Outer Mold Line (OML) transitions and maintains structural integrity. Advantageously, the turnbuckle allows surface mounted antennas and internal electronics to span structural sections of the projectile. The minimal OML produces less turbulence and drag. Finally, the turnbuckle is structurally robust for gun launched applications.Type: GrantFiled: March 19, 2021Date of Patent: December 27, 2022Assignee: United States of America as Represented by the Secretary of the ArmyInventors: Ryan Hanc, Brian Peterson

Patent number: 11519681Abstract: System for a delayed-opposed-piston gas action assembly. Specifically, the system is comprised of a bolt, a bolt carrier, a gas block, a bolt piston, and a vent piston. Each piston will have a corresponding piston cup that will act on the piston from the gas discharged from the round. Each piston will also have a corresponding spring to bring the piston back to its original position after the gas has dissipated from the system. During the process of the firearm being discharged, the two pistons will act on the bolt carrier, causing the casing of the round to be ejected from the firearm, and a new round to be loaded into the firearm, so that the firearm can be discharged again.Type: GrantFiled: April 17, 2021Date of Patent: December 6, 2022Inventor: Jordan Kristomas Kennedy
