  • Patent number: 9273943
    Abstract: A projectile comprises a payload and an aerodynamic outer housing. The outer housing is arranged, in launch and flight configurations, to surround the payload. The outer housing is further arranged, in the launch configuration, to be launched from a barrel of a launching gun or cannon. The outer housing is further arranged, in the flight configuration, to have a bi-tapered shape that is elongated along a fore-and-aft direction and has a longitudinal profile that tapers in both fore and aft directions. The outer housing is arranged to assume an exoatmospheric configuration upon reaching a target distance-from-launch, a target time-from-launch, a target altitude, or a target velocity. In the exoatmospheric configuration, either (i) the outer housing is arranged to release the payload or (ii) the outer housing and payload are arranged in a propulsion configuration. The projectile can include various additional components or adaptations to enable or achieve specific launch objectives.

  • Patent number: 8813736
    Abstract: A sport blow gun is a blow gun which is a tube with a bore, a loading end and a muzzle end. A projectile is inserted into the loading end and blown out the muzzle end by the user's breath. The main tube features a safety device which prevents a projectile from falling out of the tube or being inhaled. One type of projectile fired from the blow gun is a dart which is usually comprised of foam or soft material, and may also be made out of a material which causes relatively little resistance as it passes through the bore, yielding higher velocity. The projectile may also be coated with a coating which reduces resistance with the bore. Projectiles may also be modified in form for aerodynamic efficiency.

  • Publication number: 20100212481
    Abstract: An improved two-stage light gas gun for launching projectiles at high speeds. The gun consists of three tubes: the expansion, pump, and launch tubes. The expansion tube contains a close-fitting expansion piston that is propelled by an explosive charge. The expansion piston in turn drives the pump piston housed within the pump tube by means of a rod connecting the two pistons. The action of the pump piston adiabatically compresses and heats a light gas of hydrogen or helium, bursting a diaphragm at a predetermined pressure and expelling the projectile from the launch tube at a very high speed.

  • Patent number: 7775148
    Abstract: Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable.

  • Patent number: 7337774
    Abstract: Rifle (1) comprises barrel (2) and loading means (15) for introducing a projectile from magazine (7) into breech (4). The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature. The propellant is preferably CO2 which is heated to 31.06° C. Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

    Abstract: This invention relates to pneumatic guns that use a source of compressed gas to launch a projectile toward a target. A variety of trigger mechanisms have been used to apply the compressed gas to the base of the projectile in such a gun. In the present invention, replaceable discs of known rupture pressure threshold are mounted in the gas launcher between a compressed gas chamber and the launch tube. The gas launcher launches its projectile by the operator causing the pressure in the launcher to build up to the rupture threshold of the replaceable disc, at which point the disc ruptures and the compressed gas escapes from the compressed gas chamber past the rupture disc to push the projectile out of the launch tube. The rupture disc is a metal disc of known burst pressure.

    Abstract: An apparatus for generating shock waves by means of a supersonic projectile to effect, for example, phase transformation of a substance. A hammer in a cylinder is accelerated by introduction of compressed air into the cylinder, whereby a plunger formed integrally with the hammer at one end thereof is thrust into a hydraulic pressure chamber filled with a liquid and disposed coaxially with the cylinder. Thereupon, a high hydraulic pressure is generated in a hydraulic pressure chamber, and this hydraulic pressure accelerates a piston in a piston chamber connected with the hydraulic pressure chamber. The piston in turn compresses a light gas adiabatically to a high pressure, and a projectile fitted at one end of a barrel is thrust forward under the force of this high-pressure gas.
