A projectile for firing from an ammunition shell. The projectile includes an elongated hollow body of a resilient material, the hollow body further having a trailing end, a mid-portion, and a leading end, the leading end being closed and the trailing end having an aperture providing access to the interior surface. A propellant is included near the leading end of the hollow body and against the interior surface of the elongated hollow body, so that the interior surface of the hollow body between the trailing end of the hollow body and the mid-portion of the hollow body defines a hollow space. The projectile is adapted for placement within the ammunition shell to allow firing of the projectile from a shotgun or the like.

A launching device for launching multiple firework shells skyward th a base having foldable wings hinged to a central body. The foldable wings fold downward and reduce the size of the base for the purpose of providing a low-profile profile shipping configuration. The base has a connector, such as an engagement cylinder, that matingly engages an elongated or tubular member that is sized and shaped to receive aerial fireworks. The engagement cylinder provides either a male or female engagement with the tubular member. An adapter is provided to adjust the diameter of the connector to fit tubes of different diameter.

A supercavitating projectile is disclosed and includes a combustion chamber, a forward-directed jet nozzle and a comparatively larger gas duct / rear-directed jet nozzle. The combustion chamber is filled with a propellant having a hollowed core. The core serves as a pathway to fluidly allow combustion gases to the jet nozzles. In operation, the propellant combusts to form gasses forced forward through the forward-directed nozzle to generate a virtual cavitator in the form of a ventilation gas bubble. Combusted gasses are also forced out the rear-directed nozzle forming a propulsion jet. The projectile therefore uses the rear-directed jet to maintain a cruise velocity approximate to the launch velocity and employs a source of ventilation gas using the forward-directed jet for supercavitating of the projectile.

In this process for producing a black body decoy flare, a composition which, when combusted, provides black body radiation is extruded. The compositions generally include from about 40% to about 70% metal such as magnesium or aluminum, from about 10% to about 40% polytetrafluoroethylene, and from about 8% to about 30% binder. Important to the operation of the invention is the production of carbon upon combustion of the composition. Accordingly, polyaromatic thermoplastics, such as polystyrene and dimethyl phthalate, serve as the binder.

A longitudinal launcher tube made substantially of polyurethane resin or plastic having a rear end closed by a transverse rear wall and an open front end. The invention allows a projectile to be housed in the tube and adapted to slide longitudinally inside it towards the front, to be expelled from it via the front end tube, means for defining with the tube and projectile a rear gas expansion chamber immediately to the rear of the projectile, and an impulse cartridge adapted on command to develop gas pressure in the rear chamber to cause the expulsion of the projectile via the front end of the tube. The apparatus is a pyrotechnic device for rigidly supporting fireworks such as mortar-type, rocket-type, projectile-type, and other pyrotechnic devices so that the launcher device is reusable, whereby the launcher substantially retains its integrity after each launch to minimize harm caused to persons and the environment.

This disclosure provides for payload delivery systems and cartridges and methods that incorporate these payload delivery systems. In one aspect, the payload delivery system can comprise a payload cup and a pleated cup nested within the payload cup and having a pleated side wall. The disclosed cartridges can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.

This disclosure provides for payload delivery systems and cartridges and methods that incorporate the payload delivery systems. The payload delivery system can comprise a stabilizer having a longitudinally cut side wall defining a series of vanes that are folded forward in the pre-launched configuration. Other aspects combine a payload cup nested within the forward folding stabilizer. Still other aspects integrate the payload portion and the stabilizer portion into a single piece that constitutes a stabilized payload cup. The disclosed cartridges can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.

An apparatus (10) for initiating and dispensing an incendiary comprises a feed mechanism (12) for advancing a line of series connected incendiaries to a dispensing location D; an injection device (14); and a cutter (16). The injection device (14) injects a substance such as glycol into the incendiary as it is moved toward, but prior to reaching, the dispensing location D. The glycol reacts exothermically with another substance such as potassium permanganate in the incendiary. The cutter (16) cuts the incendiary into which the glycol has been injected from the line of series connected incendiary. After the incendiary has been injected with the glycol and cut by the cutter (16) from the line, the feed mechanism (12) advances the incendiary to the dispensing location D where it is dispensed by the action of gravity from the apparatus (10).

A pyrotechnic display device configured to ignite solid pyrotechnic compositions or aerial shells within a launch tube prior to propelling them on a desired arc. A smokeless pyrotechnic propelling charge is disposed within the launch tube below the solid pyrotechnic compositions, and separated therefrom. An ignition source is disposed in operative relationship to the pyrotechnic compositions or aerial shells, which are ignited prior to ignition of the smokeless pyrotechnic propelling charge.

A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.

A system and method are disclosed for controlling the launch and burst of pyrotechnic projectiles in a pyrotechnic, or “fireworks”, display.

The invention relates to a flame stable burner, characterized in that it comprises a circle or rectangle cup body, a rectangle tube set in the cup body and a taper ring body set at the middle-upper part of the tube; the top edge of said tube is higher than the top edge of said cup body; a distance is stayed between the bottom edge of said tube and the bottom face of said cup body; multiple air inlets are set at the bottom face of said cup body; a fuel nozzle connected with the fuel air source passes through the center of bottom face of said cup body; axes of said cup body, said tube, said ring body and the nozzle are the same. The invention is provided with reasonable design and has a very good path for mutually burning internal and external flame. The path can make external flame burn internal flame when it is burned at the first time and make internal flame burn external flame blown out so that stable burning in the invention can be insured effectively and it is not quenching. The invention can be used in torch in Olympic game or other sports meeting, celebration fire altars and picnic fire.

A "crash-bang" shotgun cartridge assembly has a projectile consisting of a weighty and frangible ballast on its leading edge, a flash-bang charge, and, in the rear, a delay fuse which is lit by the detonation of the propellant charge in the cartridge. The weight of the ballast insures greater stability in flight, and accuracy in targeting, thus extending the range of the crash-bang cartridge. In addition, the weighty and frangible ballast disintegrates into low mass, low energy (and therefore less-lethal) fragments when the flash charge detonates.
