Abstract: The present invention relates to an innovative hollow bullet design, which fundamentally diverges from conventional solid bullet configurations. This design encompasses a brass casing, gun powder, a plastic wad, and a distinctively structured nozzled projectile. The nozzled projectile features a hollow portion that starts wider at the proximal end and narrows towards the distal end, ingeniously manipulating airflow to enhance kinetic energy during flight. This unique aerodynamic efficiency potentially increases impact force and stability over extended distances. The bullet maintains standard size and weight, ensuring compatibility with existing firearms, and offers significant improvements in performance for both civilian and military applications.

Abstract: Dynamic ram accelerator operation permits operation with lower acceleration, permitting launch of acceleration sensitive payloads such as crewed vehicles. Operational cost is reduced, and reliability improved, by reducing or eliminating internal consumable parts. Relative motion between a projectile and propellant at entry to the ram accelerator enables initial ram combustion at relatively lower velocity. Valves may maintain separation between sections within the ram accelerator that contain different propellant compositions. Timing of valve opening and closing is coordinated to provide conditions suitable for ram combustion. Control over propagation speed of propellant within the system may be obtained using one or more of baffle shape, baffle spacing, propellant temperature, propellant pressure, propellant mixture, temperature of components such as baffles, and so forth. Before the projectile is launched, internal separators between sections are removed, providing an open path to the ram accelerator exit.

Abstract: A semiautomatic shotgun comprising a receiver, a barrel, a forward gas block assembly attached to the barrel, a slider assembly rearward of the gas block assembly extending into the receiver. Upon firing a shotshell the explosive gases in the barrel are diverted through two ports into the gas block assembly, specifically into a pair of lateral pressure relief valves positioned on both sides of the barrel. The pressure relief valves further having a gas pathway from the barrel provided by clusters of holes less than a specific size and on-center with the barrel axis. A piston is forced rearwardly and engages a slider of the slider assembly that is linked to a breech block in the receiver. The breech block loads unfired shells and ejects the fired shells accomplishing the semiautomatic recycling. The dual pressure relief valves actuate to moderate and limit the gas pressure that enters the piston chamber when using shotshells of different power levels thereby providing consistency in the recycling operation.
