A launchable grenade system is backwards compatible with conventional launch platforms and is capable of launching a variety of payloads at greater range and increased launch velocity, and with significantly improved targeting accuracy. The grenade is pre-packaged in a disposable launch canister that effectively confines launch ejection gases behind the projectile until it exits the canister. Additional enhancements in one or more embodiments, include collapsible aerodynamic stabilizers that are folded inside the launch canister prior to firing and deploy in flight to improve projectile stability and ballistic performance; electronic fuzing for improved repeatability and targeting precision, next-generation digital capabilities that include electronic device identification, failsafe and device monitoring; and momentum arresting forward expulsion of the payload to reduce blunt trauma hazard from projectile hardware and to provide for short distance targeting at significantly greater speed.

Launchable grenade system

A rifle muzzle launched projectile having a launch tube defining an interior cavity, and having an opening at one end with an inner diameter sized to fit over the end of a rifle muzzle; a bullet trap located in the launch tube cavity; and a payload assembly mounted on the launch tube. The payload assembly is further configured for safely releasing a payload in a controlled manner. The payload assembly also includes a casing for retaining an aerosol composition; a propellant located in the casing; a primer for igniting the propellant; and a frangible portion of the casing in contact with the aerosol composition.

Rifle-launched non-lethal cargo dispenser

Disclosed is an aerosol generating device comprising a cartridge containing a propellant. When ignited, propellant gases expand through a diffuser, then through and into a clearing pad and then through and into a filler area, thereby de-agglomerating and fluidizing the filler and increasing pressure until a frangible end seal on the retainer end of the cartridge ruptures and releases the filler as an aerosol cloud. Methods for disseminating an aerosol and for using the device are also disclosed.

Propellant-based aerosol generation devices and method

A particulate aerosol dissemination device comprising a shreddable belt is isclosed. The belt has a plurality of individual cells aligned along the belt length and which extend across the belt width. The cells are separated by partitions extending between the cells across the belt width. The cells are capable of holding a solid aerosol filler comprising any one of the following: obscurant or smoke generating materials; pesticides; insecticides; fungicides; riot control agents; fertilizer; and feed. A method for disseminating a solid particle aerosol using the belt and a process for manufacturing the aerosol belt segments is also disclosed.

Solid particle aerosol belt and dissemination method

An aerosol generating device comprising a casing having a base end and a ainer end, with a firing primer mounted through the base end and extending into a propellant zone which contains a propellant. The firing primer is thereby detonationally connected to the propellant. A diffuser plate is mounted inside of the casing on a side of the propellant zone opposite to the firing primer. A filler area inside of the casing is adjacent to the diffuser on an opposite side to the propellant zone. The filler area contains particles of a powder having interstitial void space between the particles. A frangible end seal is attached to the casing within the retainer end, with the frangible end seal being positioned adjacent to the filler area on an opposite side of the diffuser. When activated, propellant gases expand through the diffuser into the fill area deagglomerating and fluidizing the powder particles and increasing pressure until the end seal ruptures and releases an aerosol cloud. A method for disseminating an aerosol using the device is also disclosed.
